Abstract

The present invention discloses a fluidized bed reactor and a reaction system, wherein the fluidized bed reactor comprises a reactor main body (1) having an inlet (11) and an outlet (12), and the reactor main body (1) comprises A reaction section (13) is provided with a catalyst bed, the catalyst bed can be in a fluidized state under the action of the fluid injected from the inlet (11); the fluidized bed reactor further comprises a gas-liquid inlet (21) ) and a gas-liquid outlet (22) and a bubble generator (2) capable of mixing the incoming gas and liquid and breaking the generated bubbles, the gas-liquid outlet (22) of the bubble generator (2) Connected to the inlet (11) of the reactor body (1). The fluidized bed reactor and the reaction system provided by the invention are simple in structure and easy to operate, and the mixing degree between the gas-liquid reaction material and the catalyst is enhanced, the gas-liquid distribution is uniform, and the interphase mass transfer efficiency is greatly improved.

Description

technical field [0001] The invention relates to the petrochemical field, in particular to a fluidized bed reactor and a reaction system. Background technique [0002] Steam cracking of petroleum hydrocarbons is the most important method for preparing polyolefin monomers such as propylene. The alkynes and diolefins produced in the propylene production process are harmful impurities that affect the propylene polymerization reaction, they will inhibit the activity of the propylene polymerization catalyst, increase the consumption of the catalyst, and reduce the properties of the propylene polymer product, so they must be removed. In industry, catalytic selective hydrogenation and solvent absorption are usually used to remove alkynes and diolefins in cracked gas. The catalytic selective hydrogenation process is simple, the propylene selectivity is high, the by-products are few, and there is no environmental pollution. It is the preferred method for green chemical processes and ...
