Vegetable oils and animal fats transesterification for biodiesel production comprises catalysis by a strong base yielding esters of over ninty nine per cent purity
NOVELTY – The vegetable oils and animal fats transesterification for biodiesel production has catalysis by a modified strong base with spontaneous decanting of glycerine. The esters are over 99 per cent pure, and the catalyst is neutralized and purified after removal of the excess alcohol. The transesterification is based on methyl and ethyl processes. USE – In petroleum chemistry.
Main Application Field
D23 (Oils, fats and waxes – including fatty acids, essential oils, but excluding butter (substitutes) and montan wax (C11B, C).); E17 (Other aliphatics.); H06 (Gaseous and liquid fuels – including pollution control. Chemical aspects of catalytic exhaust systems for cars are included as well as liquid or gaseous fuels of non-petroleum origin e.g. methanol or ethanol-based fuels. Combustion improvement additives for liquid fuels are included (C10L).); J04 (Chemical/physical processes/apparatus – including catalysis, catalysts (excluding specific e.g. enzymatic or polymerisation catalysts), colloid chemistry, laboratory apparatus and methods, testing, controlling, general encapsulation, detection and sampling (excluding clinical testing) (B01J, L).)
