CATALYST OF ISODEWAXING, METHOD OF PRODUCING WAXY DIESEL FUELS AND THE USE THEREOF

摘要

The invention relates to the field of oil refining, namely to the development of an isodewaxing catalyst and a method of producing waxy diesel fuels of winter and arctic grades using the developed catalyst. The isodewaxing catalyst of diesel distillates contains, as an acid component, a mixture of high-silicious zeolites, hydrating transition metals – nickel oxide, molybdenum oxide, and/or tungsten oxide, copper oxide, promotor boron and/or phosphorous oxide, and binder aluminum oxide in the following component ratios, mass% - 45.0-70.0 of zeolite mixture (acid component); 6.5-20 of hydrating transition metals (in the form of oxides); 0.3-1.5 of copper (in the form of oxide); 2.0-4.0 of promotor; up to 100.0 of aluminum oxide; wherein in the process of isodewaxing, the catalyst is used in sulfide form or metallic form.
