METHOD FOR PREPARING A CATALYST AND METHOD FOR OBTAINING DIESEL FUEL USING THIS CATALYST Russian patent published in 2019 - IPC B01J37/10 B01J29/40 B01J29/87 C10G11/05

Abstract RU 2681949 C1

FIELD: technological processes.

SUBSTANCE: invention relates to a method for producing diesel fuel with low pour point, namely winter and / or arctic diesel fuel from summer diesel fuel. Method for preparing catalyst for producing diesel fuel in the process of dewaxing diesel fractions on the basis of zeolite of aluminosilicate or gallium-aluminosilicate composition, selected from the ZSM-5, ZSM-11 series, or their mixture, pretreated with solutions of organic or inorganic acids and granulated with aluminum oxide as a binder, said porous catalyst is treated with superheated steam at a temperature above 650 °C for at least 5 hours. A method for producing diesel fuel in the process of dewaxing diesel fractions with a pour point of at least minus 5 °C at a temperature of at least 280 °C is described, a catalyst prepared as described above is used as a catalyst.

EFFECT: increase in the output of diesel fraction with low pour point from summer diesel fuel with pour point of not less than minus 5 °C and increase in duration of catalyst regeneration mileage.
