METHOD hydrotreating in an acidic environment FOR DIESEL FUEL

摘要

FIELD: chemistry.;SUBSTANCE: method involves hydrotreatment of material with the boiling point interval of diesel fuel containing at least 500 ppmv of sulphur under conditions which are effective for hydrotreatment and dewaxing of at least part of the hydrotreated material in the presence of a dewaxing catalyst under conditions which are effective for catalytic dewaxing. The dewaxing catalyst includes a molecular sieve having the ratio SiO₂:Al₂O₃ equal to less than 100, and metal oxide binder, and the dewaxing catalyst has the ratio of surface area of zeolite to external surface area of 80:100.;EFFECT: method enables to obtain diesel fuel with improved properties, particularly low clouding point, using a catalyst with high catalytic activity.;15 cl, 6 dwg, 2 tbl, 8 ex
