Additives shmadditives... But yeah, okay, it's a problem if you live in the frozen zone. Someone's been trying to sell me on an additive to reduce NOx. Apparently it does indeed reduce NOx, and simultaneously CO, but otoh I think NOx is an overblown problem, I'm always a bit suspicious when people chuck the NOx objection at biodiesel. Better to debunk the thing rather - "solving" it via an additive lends it too much credence: ie, biodiesel ain't no use on its own unless you use an additive. Anyway, if anyone's interested, it's this: "There still remains a problem with biodiesel and one that we can now say with some confidence that a solution has been found. By its nature - containing more BTUs - biodiesel burns hotter. This produces NOx emissions - a leading contributor of smog (you will notice that most NOx studies done on biodiesel compare biodiesel to petrodiesel rather than discuss the actual NOx emitted). To reduce these emissions the engine has to be modified. Unfortunately, when the engine is leaned out this causes the carbon monoxide (CO) emissions to increase. It was the government's ill advised use of MTBE that was supposed to reduce the CO emissions. This means any increases of CO emissions are just not acceptable. This takes us back to the NOx. The technology used in the St. Mary's test is in fact the same technology used in the RxP fuel additives for gasoline and diesel now sold nationwide in stores like AutoZone and Wal-Mart. A graduate student, Richard Hiatt, from the University of Arizona contacted RxP and worked with Dean Johnson, the inventor of the technology, to come up with a biodiesel blend. Adding this technology to an already great product - biodiesel - will not alter the fuel's other good qualities or add to the end-user price. It will only end the debate over NOx emissions and help get biodiesel in more and more fuel tanks across our nation.

Cox Staff writer Chris Sellars, a sales representative with Supreme Oil Co., and Bill Chihak, chief engineer at St. Mary Medical Center, stand in front of the boilers in the St. Mary basement. (Leo Hetzel / Press-Telegram)Long Beach fuel salesman Chris Sellars could hardly get a hospital to return his phone calls a few months ago. Now he's the one receiving messages from them. The product he wanted to tell them about was soybean biodiesel. Mix it with a special additive, he would say, and it'll fuel a hospital boiler for less than the cost of natural gas. Just one hospital, St. Mary Medical Center in Long Beach, took him up on it. Three months later, Sellars and the hospital's boiler operators were burning a special biodiesel mixture that met the clean-air standards of the Southern California Air Quality Management District. By late May, soy was fueling all of St. Mary's laundry, sterilization and heating operations. Suddenly, Sellars' product is sparking hope amid the state's energy crisis. Just one hospital, St. Mary Medical Center in Long Beach, took him up on it. Three months later, Sellars and the hospital's boiler operators were burning a special biodiesel mixture that met the clean-air standards of the Southern California Air Quality Management District. By late May, soy was fueling all of St. Mary's laundry, sterilization and heating operations. Suddenly, Sellars' product is sparking hope amid the state's energy crisis. "We've had dozens of hospitals call us," he continued. "We've had the city of Santa Monica call us. We've had museums call us." Word of the fuel's success is spreading fast, which is great for Supreme Oil, the Phoenix-based company for which Sellars works. It's also good publicity for the hospital, the Massachusetts fuel supplier and a Florida company that invented a special additive that makes the biodiesel burn more cleanly. More testing needs to be done to settle some doubts, but the people at St. Mary say they're hard-pressed to find anything wrong with their new biodiesel. No other hospital in the nation uses anything like it. "This is just an incredible finding for us," said the hospital's facilities director, Mike Mathis. "We just kind of stumbled upon this." Biodiesel isn't for everyone, at least not yet. It is particularly suited for hospitals only because their huge boiler systems typically run on either gas or liquid fuel, and because their backup power generators can hold large amounts of liquid fuel. Another reason biodiesel looks good these days is the high price of natural gas. Even Sellars admits that biodiesel didn't make economic sense a year ago, before natural gas prices skyrocketed in California. Though big in Europe, use of biodiesel in the United States has been limited mainly to vehicle fleets, where it is often mixed with regular diesel. The biodiesel industry hopes Sellars' work will open up a whole new market. "This is a first step in expanding the use of the fuel," said Jenna Higgins, spokeswoman for the National Biodiesel Board, a Jefferson City, Mo., nonprofit trade association. While several additives are being tested for their ability to reduce smog-causing emissions, she said, "this is the first one we know of that's very successful and that's being used immediately." World Energy, the Boston company that manufactures the biodiesel Sellar sells, is performing its own tests on Sellars' formula. The goal is to find broader uses for the nontoxic fuel. But World Energy's western region director, Graham Noyes, said the company doesn't want to get ahead of itself. "I think we need some more testing to confirm that we can do better than natural gas," Noyes said. A key question to answer, he said, is how effective the additive is at reducing biodiesel's nitrogen oxide emissions, which contribute to smog. The Los Angeles-based Coalition for Clean Air agrees that the biodiesel industry must provide a clear indication of how much nitrogen oxide Sellars' mixture produces. And until that happens, coalition policy director Todd Campbell said he remains skeptical of biodiesel as a viable fuel alternative. "Just meeting the (air quality) requirements doesn't mean it's clean," Campbell said, pointing out that emissions-reducing additives usually come with their own drawbacks. "I think it's premature to say biodiesel's our answer and go forward until we know much more about this field," he said. Sellars insists that the key lies in mixing the biodiesel with RxP, the special additive for which Supreme Oil has an exclusive nationwide distribution contract in biodiesel applications. "(RxP) does unbelievable things to diesel fuel," he siad. "It makes it so much cleaner." RxP Products, the St. Petersburg, Fla., company that manufactures the additive using a complex process it calls "radiant containment," has been selling the solution for 11 years. Its customers mostly use it in locomotive and ship engines. Company President Don Woodward said he's pleased, if not a bit surprised, to hear of a new market for the additive. "We're just glad to be part of the party," Woodward said. "We're glad that we can help out." Sellars shares their sense of having played a small role in what could be a hopeful alternative energy solution. "I just put two and two together," he said, "and came up with kind of a unique use for biodiesel." Hey Keith In order for St. Mary's Hospital in Long Beach to be able to use biodiesel the NOx readings had to be below 40 ppm. Biodiesel alone cannot achieve that low number without increasing the CO readings. Already twelve other hospitals in the southern California area have expressed an interest in switching from natural gas to biodiesel as a result of those tests. By the way, don't believe the line that natural gas is a clean burning fuel. In many cases it is worse than gasoline. At any rate, I'm like you and would like to see more and more biodiesel used. Totally replacing petrodiesel however, will take some doing. We use about 27 billion barrels per year. Right now only about 500 million gallons of biodiesel can be produced - and that is getting up to full production. The U.S. has the capacity to produce around 200 million gallons now. That means the best we can hope to achieve at full production is B2. I received an e-mail from Australia about NOx in biodiesel that I would like for you to see: Australia's research organization CSIRO, is currently carrying out a desk top life cycle analysis of alternative fuels. About the only negative associated with biodiesel is the increased NOx compared to ULS diesel. Therefore I am keen to learn more about this additive that will reduce NOx. Believe me the rest of the world is looking for a way to reduce NOx emissions from biodiesel just like we are. Thanks Don Woodward http://www.calstart.org/newsSearch/selDis.html?cmd=98083902 CALSTART -- News Notes 06/27/2001 - Biodiesel Blending Technology Lowers CO, NOx St. Petersburg, Florida - A new additive shows promise for reducing carbon monoxide (CO) and oxides of nitrogen (NOx) in biodiesel fuel. Biodiesel is generally cleaner-burning than most petroleum based fuels, except in NOx emissions. A release from RxP Products, Inc. (RxP) describes tests based on California South Coast Air Quality Management District (SCAQMD) standards, in which a biodiesel blend with the new additive produced CO readings 74 percent below the SCAQMD limit of 400 parts per million (ppm), and 30 percent below SCAQMD's limit of 40 ppm for NOx. Not only does the blend surpass results of conventional diesel, it also outperforms early tests on natural gas. RxP claims the additive blending will not significantly impact pricing of biodiesel. Arizona-based Supreme Oil has been selected to market the additive, which will be distributed through retail and auto-specialty stores. http://ens.lycos.com/e-wire/June01/26June0101.html RxP Products Announces Combustion Technology Reduces Oxides Of Nitrogen Emissions In Biodiesel Supreme Oil Chosen to Market Technology ST. PETERSBURG, FL, Jun. 26 -/E-Wire/PR Newswire/-- RxP Products, Inc. (http://www.rxp.com) President Don Woodward announced today that Arizona-based Supreme Oil has been chosen to market technology used to reduce carbon monoxide (CO) and oxides of nitrogen (NOx) emissions from biodiesel. Tests conducted June 13, 2001 on a boiler at St. Mary's Medical Center in Long Beach by World Environmental, a laboratory approved by the South Coast Air Quality Management District, showed a significant decrease in CO and NOx emissions when biodiesel treated with an additive supplied by RxP was used. "The allowable limits were 40 parts per million (ppm) of NOx and 400 ppm of CO," said Chris Sellars, a representative from Supreme Oil's Long Beach, California office who was present for the tests. "The CO readings were seventy-four percent (74%) below the requirements and the NOx readings were thirty percent (30%) under," said Sellars. "This boidiesel blend also surpassed earlier results on natural gas." "We assume many people from the biodiesel industry will be interested in this technology," says Woodward. "Although biodiesel is a much cleaner burning fuel than petrodiesel, sales of this new alternative fuel have been hampered by the NOx problem." Woodward maintains the addition of this technology to biodiesel will not significantly impact the selling price of biodiesel. "We presently sell additives for gasoline and diesel engines through leading retailers like Wal-Mart and AutoZone Auto Parts Stores," says Woodward. "Our technology has been field-tested by hundreds of thousands of real users over millions of miles of normal driving conditions. We also supply products used in locomotive and marine engines. Our technology works in all hydrocarbon combustion." "We will have our skeptics, and should," says Woodward, "and we expect testing to be an ongoing and day-to-day activity in this field of study. But to my knowledge, we have the only technology around that will reduce NOx and CO emissions in biodiesel. Others are welcomed to try."
