Coal Diesel?

Anyone heard any of this???

Coal turned into a gasious state, then liquified, comes out clear, and burns cleaner than Bio, or regular diesel, with better performance or so they claim...

Wonder if this is somthing that van be made at home, if they were making it in the hitler era in industry, no reason I can't do it in my garage.

If it's the current process for synthesizing #2, it is most likely *not* a home process.

I believe the process involves superheating the carbon/hydrogen source with steam under very high pressure. This causes the molecules to separate into their component atoms (or ions). Maintaining the high temp/high pressure conditions, the mixture is passed over/through a catalyst to form new molecules. Holding the mix at one temp will produce #2 oil; holding it at some other temp will produce gasoline.

As I understand, this process works real well with natural gas; some of the large oil companies are building gas-to-liquid (GTL) plants in the middle-east, where there is a superabundance of natural gas and no way to ship it cheaply. Liquid fuel is much cheaper, easier and safer to ship.

Do a web search for "gas to liquid" fuel. You'll find quite a bit of eye-opening information. Very good lubricity, 70 cetane, no nitrogen or sulphur in the fuel, and no aromatics are a few of the details.... http://www.energy.ca.gov/afvs/vehicl...heets/gtl.html is a good place to start.

There are plans in the works for coal to diesel plant in my area, whether it happens or not depends on the price of fuel, an article I read about it awhile back stated that it would be $3 a gallon to be feasible, at least that is what I seem to remember.

Dosent sound like the best idea to me. Still burning fossil fuels, those still arent renewable fuels the last I heard. I wont support that, but I will support Bio-D and Ethanol.

When I have the cash to play with, I'll convert a TDI to run on ethanol. And I'll print a bumper sticker for it: "We Run On Ethanol"

Yeah, Fischer-Tropsch has been around since the 1920s. Actually, what F-T does is make a feedstock usable in most refineries for both gasoline and diesel.

Back in the late 70s the DOE funded a pilot plant at Catlettsburg, KY for an improved F-T process called H-Coal. H-Coal did indeed produce more feedstock per ton of coal and it refined quite nicely into synthetic gasoline and diesel at the adjacent refinery.

H-Coal worked as advertised but it had some downsides. The process generates a waste product that is called “char.” Char is mostly ash and the unreacted carbon from the coal. Char could, I suppose, be burned in a fluidized bed boiler but it is very high in ash and sulfur and hard to ignite. I doubt any other type of combustor could burn this stuff soothe DOE, back then simply landfilled the stuff. Figure 800 to 900 pounds of char per ton of coal reacted. The show-stopper is cost. H-Coal would have been competitive if gasoline had been selling for $3/gallon (1980 dollars). What would a 1980 dollar be worth today? Are we talking $5/gallon?

Another show-stopper are the federal New Source Review regs – 40 CFR 52.21. These are the regs that have prevented any new refineries from being built since Jerry Ford was President. (Actually a small refinery was permitted last year but that is the first since 1976.) The body of regs surrounding refineries and chemical plants is so daunting I doubt one would ever be built in the US.

I don’t look for synfuels to pull our fat from the fire unless there is some serious rationalization of environmental regulations.
