Abstract

The invention discloses a radial flow-type fixed bed residual oil hydrotreating reactor. The reactor of the present invention mainly comprises members of a housing, a central shaft oil inlet pipe, and a bottom hydrogen distribution disc; in a residual oil hydrogenation reaction process, raw oil mainly flows in a reaction diameter direction in a catalyst bed layer, and reaction supplemented hydrogen flows from bottom to top. The residual oil hydrogenation device of the invention has good operation flexibility, can realize synchronous inactivation of various catalysts, effectively prolongs the running period of the device, and makes full use of the active resources of residual oil hydrogenation catalysts.

Description

technical field [0001] The invention belongs to the technical equipment field of residual oil hydrogenation, in particular to a radial-flow fixed bed residual oil hydrogenation treatment reactor. Background technique [0002] Hydrogenation of residual oil is one of the main technical approaches to lighten heavy oil. At present, hydrogenation reaction technologies such as fixed bed, moving bed, ebullating bed, and suspension bed have been developed for residual oil hydrogenation. Among them, fixed-bed hydrogenation technology has developed rapidly with the main technical advantage of simple and stable reaction process operation, and has become the most mature mainstream technology for residual oil hydrogenation. More and more refineries choose fixed-bed residual oil hydrogenation and residual oil catalytic cracking The combined process achieves the purpose of producing high-quality gasoline, kerosene, and diesel in a large amount, and the economic and social benefits are rem...
