METHOD FOR DEWAXING AND DEAROMATIZATION OF HYDROCARBON IN SUSPENSION REACTOR Russian patent published in 2021 - IPC C10G45/46 C10G45/60 B01J8/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing hydrocarbon fluid and includes a stage of catalytic hydrogenation of a hydrocarbon fraction in the joint presence of a dearomatization catalyst and a dewaxing catalyst in a single suspension reactor. The amount of the dearomatization catalyst is from 0.1 to 6 wt.% relatively to the weight of the hydrocarbon fraction, and the amount of the dewaxing catalyst is from 0.1 to 6 wt.% relatively to the weight of the hydrocarbon fraction, where the hydrocarbon fraction has a sulfur content below 15 pt./m, where the reaction temperature is in the range from 180 to 325°C.

EFFECT: improved properties of low-temperature fluidity and a low content of aromatic compounds, it requires lower costs, in particular, has an increased degree of transformation.
