Re: [Biofuel] Dear Bob Allen was Re: There's no proof of globalwarming

[Ken Riznyk]

Sorry jet fuel weighs 5.22 pounds per gallon not 8. 
The carbon coefficient for jet fuel is that it
produces 19.33 million metric tons of CO2 for every
quadrillion btu. 57,000 US gallons, 138,000 btu per
gallon, yields 7.66 billion btu, producing about 152
metric tons per 8000 miles or 15.2 tons per 800 miles.
A full tank would actually weigh 148.77 tons. 800
miles would use 15.1 metric tons of fuel. 
Also just because some newsreader who probably has
zilch science smarts reads some false numbers doesn't
negate the concept of global warming.

Don't forget to subtract the weight of the hydrogen that's burned off 
before you add the weight of the oxygen.

Re: [Biofuel] Dear Bob Allen was Re: There's no proof of globalwarming

[Richard Littrell]

Dear Ray,

I think the problem is that the learned responders to your question
failed to start at the beginning.  The weight of the carbon dioxide is
the sum of the weight of the fuel plus the weight of the oxygen from
the air that combines with the fuel.  The weight of the oxygen is not
figured in the weight of the fuel as it is added literally on the fly
as the jet passes through the air.  You take one pound of fuel and add
the weight of the oxygen you pick up from the air as you fly and you
get three pounds out in the exhaust.   You asked for the time and they
told you how to make a watch.

But very roughly put and depending on the efficiency of combustion, it's
not too difficult to see that one pound of a specific type of fuel going
into a turbine or engine (a long carbon chain) can turn into two or
three plus pounds of CO2 coming out.

Re: [Biofuel] Dear Bob Allen was Re: There's no proof of globalwarming

[Appal Energy]

Ray,

> out... everything i have ever been taught
> says thats not possible

Think of it like three different spherical magnets, one small, one medium and 
one large. All of them weigh differently because they are different sizes, but 
each cubic inch of material weighs the same.

At the start, the medium sphere is joined to the small sphere. (This represents 
the carbon atom and the hydrogen atom.) After the hydrogen is burnt off the 
medium sphere (carbon) is still magnetic and it starts to seek something else 
magnetic to bond to. The most magnetic thing near it (the large oxygen sphere) 
zips in to bond with the medium sphere (carbon).

Now you have a medium and a large sphere bonded together where you once had a 
medium and a small sphere. Since the large oxygen magnet weighs more than the 
small hydrogen magnet you have a pair of magnets that now weighs considerably 
more than the original pair.

Way simple and only partly accurate, but concise enough for a person to get 
their brain around the first or second time they think about it.

Just don't start thinking about how small all these particles are and how many 
hundreds of billions are shifting around every millionth of a second inside a 
space the size of a pea and you shouldn't feel too overwhelmed with the general 
concept of atomic polarities/attractions.

But very roughly put and depending on the efficiency of combustion, it's

Re: [Biofuel] Dear Bob Allen was Re: There's no proof of globalwarming

[Zeke Yewdall]

For heavy fuels of indeterminate chemical composition, I usually use
2.5 to 3 for a rule of thumb for lbs of CO2 produced for each lb of
fuel consumed.  I was actually suprised that this example was about
the same weight of CO2 as fuel.

[Appal Energy]

Ray,

This is a the short version of a long-winded explanation as to why the 
weight of carbon dioxide appears to be so disproportionate after burning 
jet fuel (or any fuel).

Jet fuel is a mixture of long, carbon-chain and carbon-ring molecules, 
including paraffinic, olefinic, naphthenic and aromatic hydrocarbons. So 
there is no overly simple method of calculating how many carbon 
molecules are in liter of fuel (at least not without a sample of it and 
a lab).

However, just for mind candy, take a look at a biodiesel molecule with 
sixteen carbons lined up in a chain. Each has one hydrogen molecule 
attached above and below it (two). One end carbon also has a hydrogen 
attached to the side of it. The other end carbon has a hydroxyl group 
(an oxygen and hydrogen molecule) attached to it. That essentially means 
that there are 33 plus 1 hydrogen atoms, 1 oxygen atom and 16 carbon 
atoms for every biodiesel molecule that ha 16 carbons in its chain. 
(Some have a few more carbons and some have less, depending upon the 
type of fatty acid (oil) they were formed from.)

Hydrogen has a molecular weight of one. Oxygen has a molecular weight of 
sixteen, which means it's sixteen times heavier than hydrogen. Carbon 
has a molecular weight of twelve. For every hydrogen burned off the 
biodiesel (or jet fuel) molecule, at least one oxygen molecule 
re-attaches. If carbon monoxide is produced, then only one oxygen 
attaches. If carbon dioxide is made then two oxygen molecules attach.

So, for simplicity's sake, when two hydrogens are burnt off one carbon 
(C+H+H=14), one or two oxygens take the hydrogen's place (C+O=28) or 
(C+O+O=44). That makes each post combustion molecule with a carbon in it 
two or  three times heavier after combustion than before.

If a person wanted to get more precise, some fuel isn't completely burnt 
in the turbine, meaning that handfuls of hydrogen and carbon molecules 
exit the combustion process partially intact. That means that the 
hydrogen-oxygen exchange isn't exactly one or two to one

But very roughly put and depending on the efficiency of combustion, it's 
not too difficult to see that one pound of a specific type of fuel going 
into a turbine or engine (a long carbon chain) can turn into two or 
three plus pounds of CO2 coming out.

Re: [Biofuel] Dear Bob Allen was Re: There's no proof of globalwarming

[Ray J]

Specs on the current model Boeing 747-400,   57,000 U.S. gallons fuel 
capacity with 8,000 mile range so it gets something like  6-9 gallons a 
mile. so lets say 8 gallons/mile, at around 8 pounds per gallon,= 65 
pounds of fuel per mile...so it uses around 26 tons of fuel in 800 
miles  but they say they put out 28 tons of co2 in the same distance?

thats interesting...
