PROCESS FOR PREPARING HYDROWAX Russian patent published in 2018 - IPC C10G65/12 C10G73/44 B01J21/12 B01J23/888 B01J37/20 B01J29/08 

FIELD: technological processes.

SUBSTANCE: invention relates to a process for preparing a hydrowax comprising steps of: (a) providing a hydrocarbonaceous feedstock which contains more than 4 wt% hydrocarbons boiling in the range of from 550 to 800 °C; (b) hydrotreating the hydrocarbonaceous feedstock with a hydrotreating catalyst in the presence of a hydrogen-containing gas under hydrotreating conditions to obtain a hydrotreated product; (c) hydrocracking at least part of the hydrotreated product as obtained in step (b) with a hydrocracking catalyst in the presence of a hydrogen-containing gas under hydrocracking conditions to obtain a hydrocracked product, which hydrocracking catalyst contains a zeolitic component which is present in an amount of at least 14 wt%, based on the total weight of the hydrocracking catalyst, and volume ratio of the hydrotreating catalyst as used in step (b) and the hydrocracking catalyst is more than 1; and (d) recovering hydrowax from the hydrocracked product as obtained in step (c).

EFFECT: object of the present invention is to develop a method in which, given the quality of the raw materials and the level of conversion, a higher ratio between heavy hydrowax and light hydrowax is obtained.
