Abstract

This method for producing a hydroisomerization catalyst is characterized by comprising: a first step, wherein a catalyst to be processed is prepared, said catalyst having a carrier, which contains a zeolite having a 10-membered ring one-dimensional porous structure, and at least one type of metal, which is carried by the carrier, selected from a group comprising a metal belonging to groups 8-10 in the periodic table, molybdenum and tungsten; and a second step, wherein the hydroisomerization catalyst, which has 0.4 to 2.5 mass% of carbon contained in a catalyst, is obtained by conducting a coking process on the catalyst to be processed using a carbon-containing compound.

Description

technical field [0001] The present invention relates to a hydroisomerization catalyst and a method for producing the same. Moreover, this invention relates to the manufacturing method of the lubricating oil base oil using a hydroisomerization catalyst. Background technique [0002] Among petroleum products, for example, lubricating oil, light oil, jet fuel, and the like are products that place emphasis on fluidity at low temperatures. Therefore, for base oils used in these products, it is desirable to completely or partially remove wax components such as normal paraffins and slightly branched isoparaffins, which are the cause of low-temperature fluidity reduction, or to convert them to other than wax components. ingredients. In recent years, hydrocarbons obtained by the Fischer-Tropsch synthesis method (hereinafter referred to as "FT synthetic oil") have attracted attention as raw material oils for the production of lubricating oils and fuels because they do not contain en...
