Abstract

The invention discloses a simulated moving bed reaction and regeneration device for solid acid alkylation and a raw material reaction and catalyst regeneration method. The device comprises a raw material and product zone, a regeneration material zone, a rotary valve and a counter-current simulated moving bed reactor. Under control of the rotary valve, a raw material in the raw material and product zone is introduced into the counter-current simulated moving bed reactor for an alkylation reaction, a product produced in the counter-current simulated moving bed reactor returns to the raw material and product zone, a catalyst regeneration medium in the regeneration material zone is introduced into the counter-current simulated moving bed reactor for catalyst regeneration, and a material produced after catalyst regeneration in the counter-current simulated moving bed reactor returns to the material regeneration zone. By means of the device and the method, the continuous and stable operation of the solid acid alkylation reaction, product extraction, moderate catalyst generation and deep catalyst generation is achieved, the operation cycle and the service life of the device are prolonged, and the operation economy of the device is greatly improved.

Description

technical field [0001] The invention relates to a device and method for solid acid alkylation, in particular to a simulated moving bed reaction and regeneration device for solid acid alkylation and a raw material for solid acid alkylation Methods of Reaction and Catalyst Regeneration. Background technique [0002] At present, one of the most important tasks of the oil refining industry is to provide transportation fuel. As an important transportation fuel, gasoline is widely used in transportation and other industries. According to statistics, by 2030, the global gasoline demand will increase by 22%. Therefore, with the increase of gasoline consumption and the increasingly stringent environmental protection standards, how to solve the problem of clean gasoline production has gradually become a hot research and discussion topic. [0003] Under the action of strong acid, isoparaffins (mainly isobutane) and olefins (C 3 -C 5 Alkenes) as raw materials to generate alkylate te...
