BAJJU DIJZIL

[buzz]

Just thought I'd open a thread as there does seem to be quite an interest among us about it.

I would also first advice making a small amount just to get the "feel"
I personally bought three litres of vegie oil from the supermarket and made a small batch.


Making it is pretty simple but its not realy enough, it usually would need to go thru a process known as washing.

This process neutralises the ph of the fuel and removes any soaps or remaining methanol.

What I inetend doing after making the biodiesel is when I have collected a sufficient ammount of biodiesel, say around 50litres, I will add the same ammount of water (the methyl-esters will float on the water) then using a suitable air pump and air stone air the liquids.
However the PH of the water should be such as to neutralise that of the biodiesel.

EG if the Biodiesel has a PH value of say 9, then the water should have a value of 5, or viseversa, so during bubbling the resultant PH values should end at 7.

Neutral is 7. IE Value of biodiesel PH + value of water PH=14

The bubbling should be left for about 8hrs. It is probably the longest part of the process but in todays modern engines I think is well worth doing.

Journey to forever.... This is a very infromative site for biodiesel.


This is what I tried using the supermarket vegie oil.

am interested, just not really convinced so far, dunno y am sort of afraid of it, hence y am stickin to diesel hehe

[nighthawk]

I'm very interested. Won't dare with Edible Oil's biodiesel though. I need quality control!

So I'll be running on Buzzodiesel whenever the samples are ready

[landymaniac]

I will have a try too but first i have to change mu distribution pump's rubber because of new chemicals. Hope that i will fing rubber that supposrts biodiesel. i had problems with my 2.3 with adible's oil biodiesel

[joe019]

Can you specify more about this?

Great Idea buzz for creating this thread here!!!

About neutralizing the PH of the product, I guess that is not that difficult. I think you can take a sample , a strip of Litmus paper and try to approximate the amount of Acid/Alkali required......

Buzz When you made your bio batch, out of the whole cocktail, what percentage of biodiesel did you extract?

I was promised some 20 litres of used veg oil, and would lilke to try it out.

Hi Joe,

I got quite a high percentage back, I have read in some forums that some even get over 100% (thats because they probably used some of the glyceryne too). I think it is safe to say you get a over 80% return from the WVO and that's being quite conservative.

Yes Re the PH value. I have bought a universal ph testing strip and of course will take a sample and neutralise it with Acetic Acid during the washing process.

I also think it is more worthwhile to titrate before going through the process instead of converting samples and determining the amounts of caustic soda and methanol.
Titration may be a bit fiddly but the result determines the exact amount of cautic soda:methanol:WVO proportions.

problems I had

total loss lift pump--it was internally polished
starting problems
extremely white smoking
cracked distribution pump seals


But someday I go to the diesel specialist and check if there are washers and fuel pipes for the 2.3 diesel engie that are compatible with biodiesel

Basically Landymaniac, pipes are no problem you can use ordinary plastic ones the problem arises with the use of rubber pipes, the biodiesel is a solvent and apart from cleaning as you described it's said to decompose rubber.

The seals are the main worry, however, it could all be a result of poor biodiesel quality.

[landymaniac]

all my fuel pipes are rubber and the cost quite a lot

kif hawwatuni qahbec ....


i'd like to try bajjudijzil if i save money but me gonna buy it off you guys if you start producing !!

le le bis serjeta issa .... anybody thinking of producing it on a large scale ? if you have a good amount of 'clients' willing to buy it i guess it will benefit both sides

[buzz]

Thing about producing to sell is getting into paying duty and price increase, it is cheaper to make and use your own as I believe to sell you will have to be charges some form of tax. Also to go inot producing for a 'clientele will require a lot more time and money which I don't have.

When I start making and using my own I will post and let you all know my results and maybe encourage other's to make their own.

The process is as difficult or as easy as you want to make it.

Buying it from edible oil doesn't realy have much benefit, the opening times are unreasonable and the price difference is ridiculous.
The only real good time to use it otherwise is before going to do a VRT test to drastically reduce emmisions!!

[joe019]

Did you do the bio cocktail yourself or what?

For all those interested in making BioDiesel, I got some 30 litres of used veg oil. I intend doing some tests with it. I won't be using all that and there is more used veg oil to come... so if you need some I'll be glad to supply you some used veggie to try making bio yourselves....

DO NOT EVER ADD ANYTHING ACIDIC TO BIODIESEL!!!!!!!

This causes the soaps to break down into free fatty acids which will ruin fuel pumps, injectors etc etc. There are no components in a diesel engine that can be damaged by alkali fuel.

Use tap water for washing fuel (not rain water if you can avoid it).

Incidentally, the concept of pH in biodiesel is meaningless. pH refers to the concentration H+ ions in an aqueous solution only - not a level of acidity in an ester. To measure this you must do a titration against a solution of known pH.

Be very wary of a lot of hte material on the Journey to Forever website. While there is alot of useful information, there is also a lot of baloney, and to the uninitiated the two are hard to tell apart.
