TOMS Triglycerides Of Modified Structure

Sandy forwarded to me your recent mail to him concerning our TBK-BD fuel (these days called "TOMS", i.e. Triglycerides Of Modified Structure). To see its potentials, I am attaching to your kind attention some further material. Sweden being in the vanguard of promoting renewables, you may be in a position to do this with respect to our fuel, to the mutual benefits of all involved. Please remember: there is bio-ethyl acetate manufacture going on in Sweden ( SEKAB Biofuels & Chemicals AB is capable of producing entirely fossil-free ethyl acetate http://www.sekab.com/chemistry/ethyl-acetate ) , so our fuel could be 100% renewable via using this reagent (as against fossil-derived methanol in the FAME process).

Please indicate what volumes of TOMS sample you want and to what address. We never used algal oil but mostly rapeseed oil and sunflower oil feedstocks. However, it makes very little difference what feedstock oil/fat one uses for the partial interesterification with (m)ethyl acetate, as the differences in fatty acid compositions of various triglycerides can be well offset via choosing the right reaction parameters, to attain the desired product properties (mainly it is all about viscosity and cold properties).

Please remember that ours is a most versatile "designer fuel" in the sense, that varying the percentage of long --> short chain exchanges on the glycerol backbone, you can get 5 cSt --> 30 cSt viscosity fuels, i.e. both D2 and D4 petrodiesel replacers, heating oils, etc.

Tomorrow I will arrange for your 10-litre TOMS sample, made last spring -- but stored properly -- from rapeseed oil, with a viscosity of 6 - 6.5 cSt at 40°C. This could well substitute/blended with D2 petrodiesel.

Of the "heavy grade" replacer (> 20 cSt) we only produced some years back, during our trial batches, so no samples remain.

But the "real thing" was to attain the 5 - 6 cSt viscosities of EU/US FAME standards, that we managed to do at last.

So please go ahead with this novel fuel and try to get the bio-ethyl acetate manufacturer involved, so that we can come forward with a 100% renewable diesel replacer.
