Suspension bed hydrogenation reactor with high pressure separator and process

Abstract

The invention provides a suspension bed hydrogenation reactor with a high pressure separator and a method. A tray type oil collector is arranged at the upper middle part of a reactor barrel, the tray type oil collector is provided with at least one chimney-like flow passage, the reactor is divided into an upper area and a lower area by the oil collector, the upper area is a stable separation area, the lower area is a suspension bed hydrogenation reaction area, the upper stable separation area of the reactor is provided with a diluted oil inlet and provided with a discharge hole for diluted oil and reacted liquid-phase material mixture, the top of the reactor is provided with a gas-phase material discharge hole, and the bottom of the reactor is provided with a reaction raw material inlet. The suspension bed hydrogenation reactor is integrated with the high pressure separator to form a whole, and the suspension bed hydrogenated materials are cooled and stabilized by adopting the arene rich diluted oil, so that coking is effectively avoided, and long-period operation of a suspension bed hydrogenation device can be ensured.

Description

technical field [0001] The invention relates to a suspension-bed hydrogenation reactor and a process, in particular to a suspension-bed hydrogenation reactor and a process for hydrocracking heavy raw materials. Background technique [0002] Due to the increasing shortage of petroleum resources and the increasingly serious trend of heavy oil, it has become an important task for oil refiners to obtain the largest amount of light oil products, so people are increasingly researching heavy oil processing. [0003] Suspension bed hydrogenation process of residual oil is one of the ideal methods for lightening residual oil. The process is generally as follows: the dispersed catalyst is uniformly mixed with the raw material oil to obtain the mixed raw material, and then the mixed raw material enters the empty cylinder reactor together with a large amount of hydrogen (the reactor can also have simple internal components, such as thermocouple tubes and distribution plates etc.), and ...
