Fixed bed evaluation device

1. Basic configuration requirements

Fixed bed evaluation deviceIt consists of a gas feeding unit, a liquid-phase feeding unit, a reaction unit, and a product separation and collection unit. Two gases are metered by a mass flow controller and enter the gas mixer for online mixing before entering the reaction unit; After being metered by a metering pump, the liquid is mixed with gas and enters the reaction unit; The reactor adopts a fixed bed reactor, and the reaction temperature is controlled by an isothermal heating furnace; The product coming out of the reaction unit enters the condenser for condensation, and then undergoes gas-liquid phase separation in the gas-liquid separation tank. The liquid-phase product is discharged from the bottom of the gas-liquid separation tank, while the non cooled gas enters the back pressure valve to regulate the pressure and is discharged.
