Re: [Biofuel] Biox process way Iso-propanol
Help, I don't see any major industry figures in those links. Are those the right ones? Unless it is the link "http://www.lipid.co.uk/infores/topics/methests/"; which I cannot open, I don't see them. Ah! I googled for it and they moved it to : http://www.lipidlibrary.co.uk/topics/methests/ I don't see anything about MTBE as a cosolvent on that page though so I don't understand "Also, the so called "Boocock process" was described by William Christie in a Lipids Technology article in 1990" that leads up to that link (unless I found a different link by the guy with the sample title) Thanks Andy On Sat, 15 Jan 2005 04:56:21 +0900, Keith Addison <[EMAIL PROTECTED]> wrote: > Yes, Bob, that's the cosmetic version.

Re: [Biofuel] Biox process way Iso-propanol
The BIOX process, a new biodiesel process developed by the University of Toronto, has successfully demonstrated, in a laboratory setting, that biodiesel fuel (produced from recycled vegetable oils, agricultural seed oils or waste animal fats and greases) may soon become a viable, cost-competitive alternative to petroleum diesel. Professor David Boocock of the University of Toronto, and developer of the BIOX Process, has examined the process of base-catalyzed transesterification (specifically transmethylation) of vegetable oils to produce biodiesel methyl esters. The kinetic data for this reaction has been previously misinterpreted. At the University of Toronto he has shown that the methanolysis is slow because the initial reaction mixture consists of two phases, and the reaction is, therefore, mass transfer limited. The problem has been solved by the selection of inert co-solvents that generate an oil-rich one-phase system. This reaction is 95% complete in ten minutes at ambient temperatures, whereas previous processes required hours. Continuous processes are now feasible. The acid catalyzed process, which is required when the substrate contains fatty acids, is complete in minutes rather than the usual several hours.

I think it is simply using MTBE or similar to create a single phase so the reaction takes place faster.

I think VERY little isopropoxide would be produced, and possibly KOH wouldn't even be soluble (this would be easy to check, of course, I'm just being an armchair commentator here :-)). Even if you could get the alkoxide to form, I bet the glycerol would be too soluble to ever drop out.

They use (somewhat iffy) co-solvents and huge amounts of methanol, which makes their cost claims hard to believe. They do say they recover all excesses and so on, but recovering the co-solvents especially would take a LOT of energy, so again their cost claims are hard to believe. And there are quality issues. There are lots of issues. If you check the archive link I gave and other archive material you'll see what the difference is.

Re: [biofuel] Biox process, still more details
As a side note, more Ontario farmers are growing Canola than in the past, and this is winter Canola. There are benefits to that in terms of crop rotations, erosion control and yields. Industrial rapeseed (as opposed to Canola) could be grown by those concerned about Canola/GM influences, and would be the choice for organic growers. The same could be done in much of the traditional "soy belt" in the US midwest, AFAIK, so that there would be soy oil as well as rapeseed oil available, to the benefit of bio-based alternative fuel users as well as farmers.

Re: [biofuel] Biox process, still more details
Another Fuel From The Farm Biodiesel gets a long-needed boost from a tax exemption, improved technologies and the ever-rising cost of petroleum. Source: Toronto Star [Aug 13, 2002] Walking through his 31-acre soybean field near Woodstock, Liam McCreery broke off a sample pod from this year's crop. By early October, the broad-leaf plants will yield white pea-size beans by the tonne. But like Rudolf Diesel, inventor of the diesel engine, McCreery, head of the Ontario Soybean Growers, also has a shrewd eye on the longer-term. "We harvest solar energy," the 38-year-old farmer says, drawing attention to the fact that plant sources such as canola or soybean combine sunlight with carbon dioxide and soil nutrients to grow. It's long been known that vegetable oil, and oil made from waste animal fats, can be used in diesel engines. When German inventor Rudolf Diesel himself proposed it, he was hoping to make a local source of inexpensive fuel available to communities and also noted that burning vegetable oil cut pollution from the workhorse engine he invented. Biodiesel emits no sulphur, reduces black, lung-clogging particle matter by 80 per cent, and produces 60 per cent less carbon monoxide than petroleum diesel. Importantly, the carbon dioxide produced from the combustion of soybean oil as biodiesel is claimed back from the atmosphere by the next crop. Biodiesel can directly replace petroleum diesel fuel or be blended in any ratio. And it is compatible with any standard diesel engine. In fact, the slippery quality of biodiesel fuel has been found to lubricate engines, prolonging life and boosting performance. Those virtues aside, high production costs and poor supply infrastructure have kept the fuel out of the mainstream for decades. But now, a new tax break on biodiesel, rising fossil-fuel prices, and breakthroughs in production and distribution may give the technology a boost. With a big push on towards greener hydro, the truck fleets of Toronto Hydro are powering along this summer on biodiesel imported from the United States. So far, the biodiesel being tested shows a significant reduction in harmful exhaust emissions, Hydro reports. Even a B20 blend (20 per cent vegetable oil and 80 per cent diesel mixture), notably cuts down on pollutants. Also this summer, more than 100 Montreal city buses are running on a diesel mixture of waste animal fat and old restaurant grease. Unbeknownst to many, Janet Ecker's debut as the new Ontario finance minister created a stir across the biodiesel community. In the June budget, a tax exemption of 14.3 cents per litre provincial fuel tax on biodiesel was introduced. Ethanol has enjoyed a tax break for years. Striving for a cleaner environment, a provincial committee has also recommended that all diesel sold in Ontario must either be biodiesel, contain ethanol, or be a combination thereof by July 1, 2006. When Tim Haig, president and chief executive officer of Biox Corp., heard about the tax exemption, he reportedly offered to give Ecker, "a big, sloppy kiss." Biox Corp. is a pilot biodiesel project in Oakville which stands to benefit from the policy. The small processing facility is producing one million litres of biodiesel from oil derived from soybeans and waste animal fat. Biox expects to open its doors commercially early next year, with a full-scale 60-million litre capacity. The Biox process, for which a patent is pending, is based on a discovery by David Boocock, a professor at the University of Toronto. About eight years ago, Boocock, now 60 and former chair of the chemical engineering and applied chemistry department, discovered a process that eliminates one of the chemical steps traditionally needed to create biodiesel. "We believe that, given the choice, everyone would choose green if the cost was the same" Tim Haig President and chief executive officer Biox Corp. The Biox process is expected to cut costs considerably. At the high-tech pilot plant, located at an old trucking depot, compact equipment consisting of coils and chemical reactors convert raw vegetable seed oil or waste animal fat into litres of golden-colour biodiesel. From start to finish, the process takes about 40 minutes. A competitor in Europe takes a litre of oil extracted from vegetable seed and turns it into a litre of biodiesel for about 25 cents. The Biox process is designed for producing the same litre of biodiesel for about 7 cents a litre (Canadian dollars). One business plan is for the company to set up franchises around the world which would lease the equipment to a range organizations, from oil companies to rendering plants or anyone else who wants to produce biodiesel and sell it. The equipment is designed to be user-friendly; other than for maintenance of the machines, no specialized technicians are required. It means that, typically transport trucks can dock at the plant and pipe in the raw material, and truck
