Re: [Biofuel] FFA decolorization
Hi Ross Hi all, Keith,the quality is not a question,according to my NIR the BD is 99.2% esters - the foolproof method - acid stage and 2 alkaline stages with glycerin removal between , Good going! Then it really seems a pity to bother about the colour. By the way, where do you get the 60% FFA oil from, if you don't mind my asking? What's it been used for to have so much FFA? but I am supplying a close circle of friends with fuel and the people asking me What is that black sh.t you are producing? :-) Friends should be more friendly. Maybe you need a suitable slogan or a brandname or something, like black is beautiful - but, strange to tell, in the English language black usually means trouble, it's white that means all the good things, now ain't that a surprise (not!). I mean they don't make black Kleenex. (Or do they?) Anyway you'd need it in Bulgarian, maybe it's not such a racist language as English. Thanks,Mr Montenegro,the activated carbon is my last mean,I somehow kept the hope that I solve the problem with some bleaching agent A bleach might cause pH problems though. The carbon should work, though I'm surprised the bentonite didn't. All best Keith since boiling the BD sounds no good to me/polymerization!/ and filtering is OK with 5 micron in the end of the line.

Re: [Biofuel] FFA decolorization
If the coloured particles (maybe with so high percent of FFA, this oil has been used for many cicles of heating or a strong treatment, and probably it has a high decomposition ratio) are quite small, bentonite has not capacity to recover from the media. The carbon is better for this purposes.

[Biofuel] FFA decolorization
Hi All, I have a lot of high acidic /~60%FFA/ oil and had no problem to esterify it, but the BD is the same dark color as the source FFA`s and I am desperately trying to bleach it without any success.I`v already tested bentonite - no result.Has anyone any idea how to lighten the BD?

Re: [Biofuel] FFA decolorization
A little bit of coloured sustances, can make a very high coloured solution, so if the reaction goes correctly, it must not be a problem. Try to bleach it with activated charcoal, heating close to boiling point and adding then. The problem is that you will need to filter it quite well to remove all the particles before using. All the best. 2007/9/26, Rumen Slavov [EMAIL PROTECTED]: Hi All, I have a lot of high acidic /~60%FFA/ oil and had no problem to esterify it, but the BD is the same dark color as the source FFA`s and I am desperately trying to bleach it without any success.I`v already tested bentonite - no result.Has anyone any idea how to lighten the BD?
