HYDROCRACKING METHOD USING REACTORS OF PERIODIC ACTION AND RAW MATERIAL CONTAINING 200 PPM WT 2% OF MASSES OF ASPHALTENES Russian patent published in 2014 - IPC C10G65/12 C10G45/02 C10G47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to a hydrocracking method of hydrocarbon raw material containing 200 ppm - wt 2% of asphaltenes and/or more than 10 ppm wt of metals. The method involves hydrodemetallisation at least in two reaction zones of periodic action, which contain a hydrodemetallisation catalyst and possibly hydrodenitration; then, hydraulic cleaning to reduce content of organic nitrogen with further hydrocracking in a fixed bed and by a distillation stage.

EFFECT: invention provides a possibility of direct treatment of raw material types containing the amounts considerably exceeding known specifications; those raw material types can be treated individually or in a mixture, thus maintaining durability of a traditional cycle.
