Bioheating
oil is the residue out of the biodiesel distillation. It consists of:
40-80 %wt Methyl ester
1-30 % wt Dimere Methyl ester (depending on polymers from Used
Cooking Oil)
1- 25 % wt Mono,-Di- and Triglycerides
1- 5 % wt Fatty acids
1- 5 % wt Organic components from
feedstock (colour, non
saponifiable)
0.1 – 0.4 % wt Ash
max. 2,000 ppm Sulphur (depending on feedstock)
