Biodiesel Available In South West London

[joker??]

Sophorolipids?????

Mine's on hand tight, as is my oil filter. Cant be doing with whacking screwdrivers through them and oil everywhere!

[gwh200]

Glad to see you're all still going. It's been sunny outside you know.

Anyway, if Mr Fuel Man (sorry Muj, I couldn't help it) is happy to send a small sample to GWH to put through his poo counter and check out, I am happy to stump up a bit of money for it. I have a natural curiosity sorry. And no, you can't have 200 litres....

oi !!!

i'll have you know that i will be using a sophisticated ir drying scale which can detect changes in mass down to 1/1000th of a gram,and a very expensive glass microfibre filter to capture the insolubles.....

















yeah all right its a poo tester !!

but muj,if we cab get a smple to me somehow and i reckon its good,and if we can agree that its all above board and that...bring it on,you could make a killing.
theres a supplier very close to me,but i would ,under no circumstances use his product.he is a complete fraud,and relies on the fact that no one knows any different,but...and its a rather important but....you came straight to the lions den and escaped with only a few mattf teeth marks

so assuming all will be well with a sample test ,lets all get happy on the cheap stuff

[CaptainBeaky]

Don't know how I managed to miss this one...

Right, First of all, please stop calling me "mr fuel bloke" or "dude"

OK, Mr Rantzen (Ester Rantzen...? )

Also, I DO NOT just filter wvo. I actually chemically reprocess it. I treat it with methanol (for the time being, i am going to be changing over to ethanol soon though) and a catalyst. I'm sorry but i am not will to say which one.

There was some work published recently on catalysis of the transesterification reaction using an organo-tin catalyst, IIRC. If you've come up with a commercial application, then good on you!

Also, I'm not will to say what quantities I use of each other. I believe that, that is fair.

Tut, tut - smoke and mirrors again: any half-competent chemist could work that out without you telling them.

Also, I am not willing to discuss my process as it's our own way of making biodiesel which makes it a good fuel. Please respect that. I would like to be as open and as helpful as possible, without giving everything away. but one this is for sure, no way in hell do I or would I add acetone to my mix.

Fine, don't disclose process details - commercial confidentiality is OK, but please don't use any "you won't understand"/blinding with science arguments on here - they will invariably backfire, which would be a shame given the apparently admirable nature of your current venture.

so is this bio suitable to be used as fuel peter ??? in other words with the information you have on it would you use it ??

[gwh200]

depends on lots dave.its tss concentration for instance,some volatiles created by using cooking oil as cooking oil wont be filtered /processed out,some sort of amino acid marker would show phosphoric/content ,this would be a good marker to show for instance how much water there is in it,also its (correct me here someone) surfactant content,a measure of its sopainess,and therefore its ph and ultimately acid content,whether natural or added through the purification process.



captain beaky sir,its not that easy to detemine quantities of additional oil content when you dont know what your looking for,if its (m)ethanol then easily detectable by looking for its organic /volatile content,and burning in a furnace and weighing etc,but if some "new and commercially secret" ingredient is present,....well finding it and its measure means a whole ramp of analysis,which apart from anything is very time consuming and REALLY expensive.i have been bitten in the ar5e before with bio and want to be 100% sure befor i use it again.

the bottom line is making bio is really not that difficult,but cutting costs is a huge temptation to cut production costs

I'm still on my 50% mix & my Surf is still running just as well.....it will be 100% soon.

If his Biodiesel conforms to EN 14214 as per his website & he is offering this to all of us at 95p a litre, is that not good news?

This chap has been selling biodiesel to some guys in the unit on the industrial estate next to where I work & they are over the moon.

Although i haven't commented on this thread but just look in and catch up on the latest i'm glad there has been someone to say that its good stuff at last that Gemini is supplying

I did mention it once before but I think it might have got lost within a marathan of posts!!

[darkdezigns]

do wot now?lol
ok can i have 2 examples?
100ltrs delivered to brighton?
200ltrs delivered to brighton?

getting bored of asking now

[gemini_bio]

hiya gwh,

can you give me an address to send the sample to please. will 1L be enough?

Break, i'm still geting you a price.

[tintin]

Dear Muj............
I have a very good friend who lives and works just round the corner from you!
If i sent him round to your address would you give him a decently sealed sample he could post to me!!!????
Then i can pass it on to GWH200 who is our " resident chemist". so it can be analyzed to the satisfaction of all!!!!
Alternatively you can text me on 07980343201 and i will give you an address to mail it to!
( friend is at the Colourhouse theatre at Merton Abbey Mills)
Thanks
Alan

I doubt the surfactant content would have much effect on acidity, although I might be wrong. Acid content in WVO is also related to usage - oxidation of loose gycerols for example due to overheating.

"What is it?" analyses are a sod, aren't they?

If Muj is doing what I think he is, then there may well be no added ingredient to find - the catalyst stays in the reaction vessel.
If this product conforms to EN 14214:2003, then there won't be any added bits to find (other than at very low levels), and it should be fine to use as a straight substitute for DERV - this is the international standard for biodiesel.

This page gives all the parameters and specified test methods.

I'm sure if you asked Muj, he would let you have a copy of the EN 14214 analysis report.

[pedantic]

the one, the only, BIO+

OK, I'm being picky - either this is new, revolutionary and better than all competitors, or it conforms to the EN14214 standard, which means it is the same as anyone else's fuel meeting the standard, to within a few decimal places.
Next generation biofuel - OK, but that refers to production method, not end product.
[/pedantic]

Muj - I'm not having a pop at you - we have just seen a lot of snake-oil touted in the past, and some folks have had their fingers burned, hence the (hopefully) healthy scepticism.
If you have succeeded in making the catalysed transesterification work on a commercial scale, then I'm most impressed!

[MattF]

but...and its a rather important but....you came straight to the lions den and escaped with only a few mattf teeth marks

You'll be having people think you keep me chained to the wall soon for protection. (And not in a kinky type way, might I add, before anyone says it).

[MattF]

this would be a good marker to show for instance how much water there is in it,also its (correct me here someone) surfactant content,a measure of its sopainess,and therefore its ph and ultimately acid content,whether natural or added through the purification process.

The main points to check for, literally, should be Ph level, glycerol/fat content and water content. It's obviously gone through the methanol/lye process, which also means it has been water washed, so Ph levels and water content are the main points. I wouldn't think suspended solids should be a problem, with all the processing it will have gone through, but no harm checking. The good old fashioned eye test is another check. Any murkiness or whatever obviously wouldn't be a good sign.

Btw, it is a couple of years or so since I last did all my research on this subject, so I might be a tad hazy on the exact specifics, but I believe the above is about right.
