Converting Cooking Oil into Biodiesel

Are you looking for a recipe or the general concept? I have found both searching the internet (in the past), but if you like, I've saved soft-copies that I can send you. I probably shouldn't post them as I don't remember where I got them and couldn't give the proper sitation credit.

In the meantime, my classmate engineered this solution and sold it to Home Biodiesel. Now you can purchase a biodiesel fuel converter from them and start making your own biodiesel without researching all the methods and dealing with the hobbyshop chemical mixing. http://www.homebiodiesel.com/

Hi Thor,

Thanks you for your input, I am looking for the recipe and what and how to.

I have seen such concept at 'Fast Track" and I think it is a grat idea to save some fuel cost of my truck.

thanks.

There is a large amount of data on the process elsewhere on the 'web.

Jeremy Clarkson demonstrated this on Top Gear about 18 months ago. He introduced an elderly Volvo 740 that was running on filtered used cooking oil with a couple of percent of white spirit added, and on a private test track it ran fine all day despite smelling like an old chip shop, allegedly!

Elastomeric components in engines have to be selected carefully to withstand attack from the different organics in biofuels as compared to petroleum-based fuels. Vehicle manuals are becoming more detailed in the area of compatibility over time. The different waxing characteristics of the fuels are significant in considering the cliamte in which they are used.

And in the UK, it is lawful to use home-brew liquid fuels on the public roads once the excise duty due on the fuel used is paid to HM Revenue and Customs; ordinarily this tax is collected via transactions at roadside filling stations.

There are lots of methods,Here's a good home brewers forum. most newer diesels are biodiesel compatable, here's a good source [ NBB ] of general use info. Be aware that the chemicals & heat involved require proper handeling & safety precautions. Palm is useful in warmer climates due to it's higher cloud point.

I heard some people in Hawaii are doing this in their backyards.

My cousin from EU drives German new SUV which has note : "do not use biodiesel". It should be some limitations in the usage of this fuel. I guess Oil Co are not very friendly to this concept.

There is a FANTASTIC website called Journey to Forever, so comprehensive that you may spend hours just researching all the general background and technical aspects of the procedure via side links they offer. It is a great site to check out for the newcomer to the biofuel wave. Good luck!

They carry a complete kit and instructions.

Saw it tested on Truckstv.com

Actually it's quite simple but time consuming.

Kinda messy and you have to figure out what to do with the by-products: glycerin and the like.

If you want to make enough to fuel a vehicle on a regular basis, you have a fair amount of work ahead of you.

Here is one of the easiest "How To's" makingbiodiesel

The basics.

Filter the used oil to remove solids. Old Jean Pants work great.

Add 15% by volume Methanol

Add 1lb of Caustic Soda, Lye (I typically use red deviel Lie it works fine) per 10 gallons of Oil Methanol mixture.

Excess Lie will only create more soap yielding less Glycerol

Mix continuosly for 3 hours ( I have rigged an old bakers mixer to fit on my 50 gallon plastic drum.)

Let stand untill stratification completes.

Skim the top layer of crud out Glycerol

pump out the BD and your done. After pumping more parcipitat soap stock will come out of soution.

* I wash my oil first by placing small voulmes in metal drums and w/ High Pressure water spray the oil down then heat the drum to remove the water and refilter with the jeans.

I have been running my Ford F350 on this for over two years I had to replace the fuel filter and add a heater to the fuel tank but to truck runs great a little less efficent but a hole lot cheaper.

google biodiesel board for top of the line information on producing biod.

PS it work in you home heater with some minor adjustments to the injectors and 90% real hydrocarbon diesel
