Multiphase reactors are reactors that utilize interfacial reactions between different phases to react the reactants on a solid surface or a liquid surface.
I. Principle of multiphase reactor
Multiphase reactors are reactors that utilize interfacial reactions between different phases to react the reactants on a solid surface or a liquid surface. Common solid-liquid phase multiphase reactors include suspended bed reactors, fluidized bed reactors and fixed bed reactors.
The principles of multiphase reactors can be summarized as follows:
1. Enhanced transfer of reaction materials: compared with single-phase reactors, multiphase reactors have more adequate transfer between reaction materials and catalysts, and higher efficiency of catalytic reaction.
2. Easy separation of catalyst: multiphase reactor can reduce the difficulty of solid-liquid separation between catalyst and reactants, and because the catalyst is in a solid state during the reaction, it is easier to separate and recover the catalyst.
3. Improvement of reaction selectivity: Compared with single-phase reactor, multiphase reactor can control the reaction selectivity more effectively by utilizing the characteristics of interfacial reaction.
II. Application of multiphase reactors
Multiphase reactors can be used for a variety of chemical reactions such as common oxidations, hydrogenations, dehydrogenations and alkylations. Below are some application scenarios for multiphase reactors:
1. Catalyst preparation: Multiphase reactors can be used to prepare catalysts with high catalytic efficiency and selectivity.
2. Chemical production: Multiphase reactors can be used to produce various chemicals, such as advanced alkylbenzene, chlorinated polyethylene, nanoparticles and so on.
3. environmental protection: multiphase reactors can be used in waste water treatment and air purification and other environmental protection fields.
4. Petrochemistry: multiphase reactor can be used for catalytic cracking reaction, catalytic hydrogenation and other chemical reactions, using the solid-liquid interface reaction characteristics, improve the reaction conversion rate and selectivity, so as to improve the yield and quality of petrochemical products.
Summarize: multiphase reactor is an important chemical reaction equipment, can effectively improve the reaction efficiency and selectivity, widely used, for the promotion of chemical production, environmental protection and other fields play an important role.
