REACTOR FOR HYDRAULIC TREATMENT OF HYDROCARBON STOCK Russian patent published in 2013 - IPC C10G45/02 B01J8/02 

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of hydrocarbon stock. Proposed reactor consists of housing with cylindrical shell ring, upper and lower bottoms, axial stock feed pipe arranged at upper or lower bottom, separation zone at reactor upper part, housing lower zone with catalyst basket with stationary bed of pelletised catalyst, reaction product discharge pipe, level and pressure control system and gas discharge pipe atop reactor housing. Reactor accommodates at least one catalyst basket confined by two perforated walls shaped to truncated cone with taper angle of -45° to +45° and dead end walls. Note here that one perforated wall adjoins the shell ring in circle and at least one unit of heat exchange elements is arranged between said perforated walls. Pelletised catalyst is arranged between said heat exchange elements. Extra separation zone and at least one annular or cylindrical bypass to communicate extra and main separation zones are arranged at catalyst basket bottom. In case stock feed pipe is arranged upper bottom, it is provided with vertical pipe extending through catalyst baskets to reactor bottom.

EFFECT: reduced hydraulic resistance, catalyst load and metal input.
