It is my understanding that when gasoline spoils it is because the short chain molocules re-join to form a long chain polymer. Now with being as I understand the bad gas therory. Is it feasible to think that under certian temps and pressures the long chain polymers can be re-cracked and good fuel be obtained from bad? Now I am not a petro-chemist but input would be great.


any one want to invest in an idea?

I think old gas "spoils" because the lighter more volatile elements evaporate, and what is left doesn't burn well and can clog things up with varnish. But so what? How much old gas is out there available to do something with? You could probably mix it with some fuel oil and burn it for a furnace if you wanted to, or put it in a waste oil heater and burn it, (local garages do that around here in the winter).

I am not convinced your correct in the bi-product process, amigo.

Old gas turns into a varnish/ lacquor type substance. I always called it varasol. Great for cleaning greasy engine parts.
It doesn't burn well at all for engine purposes. If you do want to reuse it as a fuel I think you have to cut it at least 4 to 1 with fresh gasoline.4 parts fresh to 1 part old. The older it is the more you need to cut it. It's called reconditioned gasoline and still shouldn't be used in fuel injection cars. Lawn mowers and 2 cycle engines should be ok.

Happy motoring.

I've burned LOTS of bad gas. If you have a car with a tank full of bad gas, it's not a big deal as long as you have a fuel filter near the engine. The last thing you want is a solid chunk of what ever getting into the FI system or the carburetor.

The info I am really looking for is the pressures as well as the temps required to crack the the spoiled fuel into "recycled" automotive fuel. I am of the belief that there is a resource that is untapped. Is it possible to home refine spoiled gas?

--is there a model of a refinery?



--what temp does the hydrocarbon chain crack at?

[BlisteredWhippet]

I don't know about recycling, but bad gas is extremely toxic.

I'm the irrational extremist yet you want to start a backyard refinery....

Now THAT is fucking rich.

I gave you plenty of solutions:

1. mix it with fresh stuff
2. bring it to a collection center to reblend

Speaking of drug habits, I'm a hell of a lot more worried about the quality of drinking water than your petroleum fix.

Refining is one of those processes that works due to scale.
Your backyard chemistry set will have a negative EROEI.

Wiki Refineries

Gee, that was tough.

I'm thinking that if you can't find stuff like this, maybe you shouldn't own a stuffed animal never mind a chemistry set.

[NABR1337]

well that is great for refining crude. I am wondering about re-refining after spoilage.

--now to adddress your negitivity.

I am not your daddy, I am not the one to project your low self estem issues on to. I do not care if you think you are some sort of internet superhero. The info you do provide gets cloaked in a shoud of negtivity that almost masks any usefullness you post. You seem to think you have my cards marked and have me pegged. Look at my post count. You cannot possible know my agenda from the 5 posts I have made. Like you I want to save the world. Where we divirge is where as you seem to think that you are the only one with answers, i look for colibrations. Now please for the simple sake alllowing the idea that i am forging to transpire, be civil and ....whatever this fourm has a nifty ignor function. Since you seem to think that this thread is a great place to attack authors, do your best cause I won`t see them Haden as for this moment forth you are ignored.(your posts will not appear on my screen)

still curious about the idea of using old gas from salvage yards to re-refine into a low cost recycled fuel.

I thought for sure there would be some-one who could at least say that this has been tried, but proved to be cost prohibitive. I have yet to hear from any one who has any creidible back round on the subject.



--- great ideas have come from home chemistry sets.

[basil_hayden]

Collaboration to solve a problem relies on a problem existing in the first place. You're inventing one, so I guess we're headed in the right direction.

As your location is not in your profile, but you can't spell worth a hoot, I'd say you're in the US. There are laws that apply to the treatment, storage and disposal of petroleum and other hazardous wastes. These laws are meant to prevent folks like you from contaminating my groundwater.

So, I repeat, small quantities can go into your car, and large quantities can be brought to/picked up by a recycler for reblending at a refinery. Why? Because of the economy of scale. Refining crude and re-refining spoiled products takes the same chemistry set.

Gasoline goes bad because the light stuff leaves, not because the light stuff joins to become heavy stuff. To refine, some of the heavy stuff needs to be cracked into the light stuff.

[crossthread]

Naber,, I'm thinking you may, or have access to a "lil" amount of "bad gas", so I'm thinking, junk yard or something of that nature recovering the Gas left in such?

I'd try getting the "old Oil" outta the engines, (long hydrocarbon chains?), blendin with the "bad gas" then "Re-Refining"...

Not everone here is crude and Rude...

HI

Sorry to drag up an old thread, but if the original author is still around, I would like to hear his idea's. With the little info provided, as mentioned, it seems you have access to small amounts of old gas, or you see recycling opportunities at scrap yards?

There is a scrap yard that I go to and I know that all the fluids are drained from the cars and recycled. The gas is the divvied up between the employees. On Fridays you can see them all walking out with their five gallon gas cans.

I know the owner is a real cheap-@ss, I bet it comes off their pay!
