Abstract
A cold-wall reactor for suspension-bed hydrogenation includes a reactor body including a reaction product outlet, cold hydrogen gas inlet and feed inlet. The reactor body includes a housing, surfacing layer and thermal insulation liner. An inner lining cylinder is fixedly arranged inside the reactor body with an outlet connected with the reaction product outlet. A side wall of the inner lining cylinder and an inner side wall of the reactor body define a cavity serving as a first circulation channel. A second circulation channel is arranged on the inner lining cylinder side wall. The inner lining cylinder communicates with the first circulation channel through the second circulation channel. In suspension-bed hydrogenation, material temperature is more uniform, reaction efficiency is improved, materials coking is reduced, thermal insulation liner issues are prevented, and the temperature of the outer wall of the reactor body is lower than the temperature of the medium.
