Abstract

A radial reactor and a process method for chemical chain reaction, the reactor includes an inner cylinder, a middle cylinder and an outer cylinder, a plurality of openings are uniformly distributed on the walls of the inner cylinder and the middle cylinder, and the wall of the outer cylinder is a closed entity; The reactor has at least two reaction zones, a closed zone is arranged between each reaction zone, and an inlet and an outlet are arranged on the outer cylinder wall of each reaction zone. The above-mentioned reactor is used for the chemical chain reaction, and the oxygen carrier is densely piled between the inner cylinder and the wall of the middle cylinder, and the reaction gas in each reaction stage is fed from the lower inlet of each reaction zone, and radially counterflows with the oxygen carrier. contact reaction. Using the chemical chain reaction process of this reactor, it has the advantages of uniform distribution of raw material gas and small bed pressure drop; combining multiple or two reactors into one body reduces the gas-solid separation device and realizes valveless operation. It not only solves the separation of gas and solid, but also solves the problems of short valve life under high temperature and easy wear of oxygen carrier in the valve.

Description

technical field [0001] The invention relates to a radial reactor and a process method using the radial reactor for chemical chain reaction, which belongs to the technology in the field of chemical chain hydrogen production. Background technique [0002] Hydrogen is an important process raw material for refineries. It is widely used in gasoline, diesel, residual oil hydrogenation and other processes to adjust the hydrogen-carbon ratio of products and desulfurization and denitrogenation. From a global perspective, crude oil is becoming more and more heavy and inferior. For large-scale refineries, the hydrocracking and hydrotreating process routes in the processing of heavy and inferior crude oil are beneficial to "eat dry squeezed raw materials." The efficiency is better than that of the coking route. With the continuous acceleration of oil product quality upgrading, the demand for hydrogen in refineries is increasing rapidly. [0003] Hydrogen production from natural gas has...
