Hydroformylation method, reaction device and reaction system using same

Abstract

The invention discloses a hydroformylation method, a reaction device and a reaction system using the same. The reaction device comprises a horizontal reactor, chamber body outlets, distribution platesand circulating pipes, wherein the interior of the reactor is partitioned into multiple chamber bodies by one or more partition plates; the upper fluid of each chamber body is communicated with eachother; each chamber body comprises a reversed self-aspirated injector mounted at the top of each chamber body; each reversed self-aspirated injector comprises a nozzle, a gas suction section, a mixingsection and a diffusion section, wherein the gas suction section, the mixing section and the diffusion section are connected with a fluid, the nozzle is formed in the gas suction section, the gas suction section is communicated with a raw material gas source fluid and communicated with the fluid above the liquid phase line of each chamber body; the chamber body outlets are formed in the lower parts of the chamber bodies and used for discharging reaction mixtures; the distribution plates are mounted in the chamber bodies and used for changing raw material gas flowing between the reversed self-aspirated injectors and the chamber body outlets; the circulating pipes are used for recovering the reaction mixtures from the chamber body outlets and then supplying the reaction mixtures to the nozzles of the reversed self-aspirated injectors; and the reactor further comprises a liquid loop pipeline used for enabling partial solution, containing a catalyst, output by the last chamber body to becirculated into the first chamber body.

Description

technical field [0001] The present invention relates to a hydroformylation reaction device and a reaction system using the device. Specifically, it relates to a reaction device for preparing aldehyde by carbonylation of olefin and synthesis gas. By adopting the method and the reaction system of the invention, the reaction efficiency can be improved, equipment investment can be reduced, and the economic benefit is high. Background technique [0002] Olefin carbonyl reaction is an important organic synthesis reaction, which plays a pivotal role in modern industry. The product aldehyde is a very useful chemical intermediate, which can synthesize a variety of important chemical and chemical products. It is the largest homogeneous catalytic reaction process in production scale so far. [Trzeciak, A.M.; Ziólkowski, J.J. Coord. Chem. Rev. 1999, 190-192, 883-900.]. [0003] The main methods for producing aldehydes from olefin carbonyls include low-pressure rhodium-catalyzed carbon...
