Hydrogenation Reactor with Surge Assemblies

Abstract

The invention discloses a hydrogenation reactor with a buffer component. The hydrogenation reactor of the present invention includes a material inlet pipe, an inlet diffuser, an upper head of the reactor, a flow-reducing equalizer plate, a catalyst bed, a catalyst support grid, a reactor cylinder, a lower head of the reactor, and an outlet collecting device, material outlet pipe and unloading pipe. The impact reduction and equalizing plate is set in the idle space of the upper head of the reactor or at the upper end of the reactor cylinder; the impact reducing and equalizing plate includes the impact reducing tray and several impact reducing trays. Distributor, the distributor includes a grid, a material drop tube and a connecting rod, the grid is arranged above the material drop tube, and the grid and the material drop tube are connected through a connecting rod. The hydrogenation reactor of the present invention is suitable for the hydrogenation reaction process, especially the hydrofinishing or hydrocracking process with relatively large reactor scale.

Description

technical field [0001] The invention relates to a hydrogenation reactor with an impact reduction component, which belongs to the field of chemical equipment. The hydrogenation reactor of the present invention is suitable for the hydrogenation reaction process, especially the hydrofinishing or hydrocracking process with relatively large reactor scale. 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...

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
