METHOD FOR PRODUCING BIODIESEL FUEL FROM SILES OF RESERVOIRS AND / OR SEDIMENTS OF SEWER TREATMENT FACILITIES

摘要

A method for producing biodiesel fuel from sludge and / or sludge of treatment facilities, including preliminary processing of raw materials, extraction of the lipid fraction, transesterification of the lipid fraction, separation of the obtained fractions and dehydration of biodiesel, characterized in that sludge of reservoirs and / or sludge of treatment facilities are used as raw materials, disintegration of raw material cells is carried out mechanically, for lipid extraction using the Folch method, which includes lipid extraction with a chloroform-methanol mixture 2: 1 by volume, followed by washing the extract with a 0.88% KCl solution and, after stratification and removal of the upper phase, with a 0.88 mixture % solution of KCl-methanol 1: 1, by volume, the finished lipid extract is dried by passing through a layer of anhydrous NaSO, then the transesterification of the dry extract with methanol in a molar ratio of 1: 9 in the presence of an acid catalyst in a methanol / catalyst ratio of 50: 1, by volume , biodiesel is extracted from the reaction mixture with hexane, the biodiesel extract is dried, passing through a layer of anhydrous NaSO.
