FIELD: chemistry.SUBSTANCE: invention relates to a catalyst for producing synthetic base oil from oligomerisation of hexane-1, having a catalytically active component in form of chromium which is deposited on a support, wherein the support used is silica gel with particle size of 2.2-4.0 mm, pore size of not less than 100 and specific surface area of not less than 300 m/g, wherein the content of chromium is in the range of 1-3 wt %. The invention also relates to a method of preparing the catalyst, which comprises depositing chromium on silica gel by impregnation with an organic solution of a chromium salt, drying the catalyst at room temperature for 2-3 hours, activating with air at temperature of 500-600°C for 3-5 hours and reducing the catalyst at temperature of 300-350°C in a carbon monoxide current for not less than 2 hours.EFFECT: obtaining a catalyst with high catalytic activity and longer service life, which considerably improves the quality of the obtained synthetic base oil.2 cl, 1 tbl, 8 ex |
