Hi

A friend asked if drip gasoline might be used instead of methanol alcohol ?

I quickly replied no. Now I am wondering.

Some one know if this would if this would be worth trying a small amount in a soda bottle ?

Petroleum Condensate [a.k.a. drip gas] is an entirely different chemical than methanol and will not catalyze the biodiesel forming reaction.

However it can be mixed with clear dry clean VO fuel and burned directly in diesel engines without converting the VO to biodiesel.

Could you suggest a vegatable oil ratio to drip gas ?

John, I have never heard of petroleum condensate, can you tell us what it is and what it is used for?

"Casinghead gasoline," "absorption gasoline," "condensation gasoline," "drip gasoline," and "natural gasoline" mean a low-octane, high-volatility, liquid hydrocarbon by-product of crude oil extraction and pumping, coal gasification, or shipping of natural gas through a pipeline. When a natural gas reserve contains substantial amounts of ethane and the higher paraffinic compounds, these are usually extracted at the production site and produced as natural gas liquids (NGL). The NGLs can be separated into fractions, ranging from the heaviest condensates (butanes, pentanes, and hexanes) through LPG (essentially propane and butane) to ethane.

not in general-

Type of VO
Operating temperature
Vehicle engine

all influence the percentages of blend components.

MBenz recommends 1% RUG in #2 diesel for every degree C below freezing. That's a good general starting point for experimentation.

Most newer diesel engine manufacturers forbid the use of gasoline in any amount.

Older diesels like the "bulletproof" five cylinder mechanically injected mercedes benz would burn almost anything that was pretty close to diesel, if you could pump it through the fuel line. That is a slight exaggeration, but illustrates the point well that not all vehicles do equally well on all blends.

Finest regards,

I've never considered gasoline as a good solvent for VO blends. The fresh stuff has volatiles that are not good for diesel engines, and the stale stuff has an ugly odor that sticks to everything it comes in contact with.

Hi John G.

We all know you don't believe in biodiesel.

But you do know enough about it to know full well that the methanol is not the catalyst, lye is. Three methanol or ethanol molecules replaces the glycerol molecule connected to the Fatty Acid chains. Other alcohols work but not nearly as well.

The caustic [NaOH, KOH] is a reagent consumed in the process, the alcohol [methanol, ethanol] is a catalyst that can be recovered after the process is complete.

Catalyst: A substance that modifies and increases the rate of a reaction without being consumed in the process.

A Reactant or Reagent is a substance consumed during a chemical reaction.

Solvents and catalysts, although they are involved in the reaction, are usually not referred to as reactants.

Of course I believe in biodiesel, know how to make it, but have moved beyond just biodiesel.

I think the winter blahs have gotten to you.

The caustic does not become part of the finished biodiesel whereas the methanol does. The excess methanol can be recovered.

Very Good.
Now why do you get it confused which is which?

What are you using, Cold Fusion?

I thought you just used raw vegetable oil. Unprocessed. Sometimes used raw vegetable oil.

I think you are misleading newbys.

If you have something personal to discuss send a PM. Your opinion of other members is irrelevant, and insignificant.

Hello John

The NaOH/KOH is a catalyst in the reaction converting Oil into biodiesel.
The NaOH/KOH is a reagent in the side reaction that is converting ffa's, WVO, and biodiesel into soap and is consumed in this side reaction.

The methanol is only a reagent in the reaction making biodiesel.
The FA's are broken off the glycerol molecule and a methanol molecule is attached to the FA.
An excess of methanol is used in the reaction to insure high conversion.
The excess methanol used in the reaction is recoverable at the end of the reaction.
The resulting molecule is often called a Methylester.
