Abstract

The invention relates to a homogeneous three-phase reactor for jet aeration. A three-phase homogenizing plate for jet aeration is arranged at the bottom of a reactor shell or inside a slurry inlet channel; a micro-pore penetrating through the three-phase homogenizing plate for jet aeration is formed in the three-phase homogenizing plate for jet aeration, so that a three-phase mixture of an oil product, hydrogen and a catalyst flows through the micro-pore, and air bubbles of the gas and liquid drops of the liquid become fine and even. Thus, diffusion and full contact of gas, liquid and solid three-phase substances are facilitated by fine and homogenized air bubbles and liquid drops. The homogeneous three-phase reactor for jet aeration disclosed by the invention can achieve full and even mixing of the oil product, the hydrogen and the catalyst, thus a full touch opportunity is created for reaction of the oil product and the hydrogen on the surface of the catalyst, so that reaction is complete and the reaction efficiency is high.

Description

technical field [0001] The invention relates to a jet aeration three-phase homogeneous reactor, which belongs to the technical field of hydrogenation catalysis. Background technique [0002] Many high-temperature hydrogenation chemical reactions in petroleum industry production need to be synthesized by heterogeneous catalytic reactions. The existing heterogeneous catalytic reactors can be divided into two categories according to the state of the solid catalyst: reactors in a static state and reactors in a flowing state. Among them, the reactor in which the catalyst is in a static state includes a fixed bed reactor, and the reactor in which the catalyst is in a flowing state includes a fluidized bed reactor, a moving bed reactor, and a slurry bed reactor. [0003] At present, most of the slurry bed reactors used in the field of high pressure hydrogenation of heavy oil are slurry bed reactors, and the slurry bed reactors that can be used in the field of high pressure hydroge...
