Abstract

The invention discloses a fluidized bed reactor and a reaction system. The fluidized bed reactor comprises a reactor main body (1) with an inlet (11) and an outlet (12), the reactor main body (1) comprises a reaction section (13) provided with a catalyst bed, and the catalyst bed can be in a fluidized state under the action of fluid injected from the inlet (11); the fluidized bed reactor further comprises a bubble generator (2), and the bubble generator is provided with a gas-liquid inlet (21) and a gas-liquid outlet (22) and can be used for mixing incoming gas and liquid and crushing generated bubbles, and the gas-liquid outlet (22) of the bubble generator (2) is connected with the inlet (11) of the reactor main body (1). The fluidized bed reactor and the reaction system provided by the invention are simple in structure and easy to operate, 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 field of petrochemical industry, 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 dienes 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 dienes in cracked gas. The catalytic selective hydrogenation method has simple process flow, high propylene selectivity, less by-products, and no environmental pollution. It is the preferred method of green chemical technology and its ...
