Producing biokerosene by integrated process involves processing raw material containing glycerides with lower alcohol in presence of homogeneous or heterogeneous catalyst, and performing transesterification of obtained material
NOVELTY – Biokerosene production involves processing raw material containing glycerides with lower alcohol containing 1-5 carbons atom in presence of homogeneous or heterogeneous catalyst at certain atmospheric pressure. Transesterification of obtained material is carried out at more than 150 degrees C temperature and certain atmospheric pressure. Transesterified product is purified in presence of high vacuum at 0.001-5 mmHg pressure to obtain residue having heavy ester (more than 16 carbon atoms). USE – Method for producing biokerosene by integrated process (claimed). ADVANTAGE – The method enables to produce biokerosene with high purity and yield. DETAILED DESCRIPTION – Biokerosene production involves processing raw material containing glycerides with lower alcohol containing 1-5 carbons atom in presence of homogeneous or heterogeneous catalyst at certain atmospheric pressure. Transesterification of obtained material is carried out at more than 150 degrees C temperature and certain atmospheric pressure. Transesterified product is purified in presence of high vacuum at 0.001-5 mmHg pressure to obtain residue having heavy ester (more than 16 carbon atoms). Decarbonylation if residue is carried out in a fixed or fluidized bed reactor in presence of a catalyst i.e. zeolite at 150-800 degrees C to obtain a mixture of hydrocarbons and oxygenated compounds. Hydrocarbons and oxygenated compounds are separated from mixture of hydrocarbons and oxygenated compounds. The oxygenated compounds are decarboxylated or hydrogenated, and then purified at certain atmospheric pressure to obtain the finished product i.e. biokerosene. DESCRIPTION OF DRAWING(S) – The drawing shows a flowchart of the biokerosene production method. (Drawing includes non-English language text).
Main Application Field
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).)
