A hydrogenation reactor having an impact reducing element

Abstract

The invention discloses a hydrogenation reactor with an impact reducing element. The fixed bed hydrogenation reactor comprises a material inlet pipe, an inlet diffuser, a reactor upper head, an impactreducing flow equalizing disc, a catalyst bed layer, a catalyst support grid, a reactor cylinder, a reactor lower head, an outlet collector, a material outlet pipe and a catalyst discharge pipe. Theimpact reducing flow equalizing disc is arranged in an idle space of the reactor upper head or above the top end of the reactor cylinder and a top distribution disc; the impact reducing flow equalizing disc is provided with a plurality of distributors and each distributor comprises a flow equalizing disc, a downcomer and a connecting rod, and the flow equalizing discs are connected with the downcomers through the connecting rods. The hydrogenation reactor disclosed by the invention is suitable for hydrofining or hydrocracking treatment processes of oil products.

Description

technical field [0001] The invention relates to a hydrogenation reactor with a shock reducing element, which belongs to the field of chemical equipment, in particular to a hydrogenation reactor suitable for oil hydrofinishing or hydrocracking treatment. Background technique [0002] In recent years, with the rapid economic development and the enhancement of environmental protection awareness, the quality and environmental protection requirements of petrochemical products are getting higher and higher. As a technical means of producing clean fuels, hydrogenation technology is playing an increasingly important role in the oil refining industry. In the hydrogenation unit, like the hydrogenation catalyst technology and the hydrogenation process technology, the hydrogenation reactor technology is an important part of the reactor system, and the three constitute the three factors of the reactor performance. In the hydrogenation unit, the hydrogenation reactor, which is the key eq...

AI Technical Summary

Problems solved by technology

Since the hydrogenation process is an exothermic reaction, the feedstock oil is unevenly distributed on the radial section of the catalyst bed, which will lead to different reaction degrees and radial temperature differences, and even local overheating, which will damage the performance of the catalyst and greatly reduce the catalyst performance. life cycle
