Catalyst performance evaluation device and catalyst performance evaluation method

Abstract

The invention provides a catalyst performance evaluation device and a catalyst performance evaluation method. The catalyst performance evaluation device comprises a reaction system, a product separating and collecting system and a liquid supplementing tank, wherein the product separating and collecting system is located at the downstream part the reaction system; the liquid supplementing tank is used for supplementing a solvent to the reaction system. With the adoption of the liquid supplementing tank structure arranged in the catalyst performance evaluation device, a catalyst required by a gas-phase reaction can keep a slurry state with certain concentration in a reactor, so that the catalyst required by the gas-phase reaction is accurately evaluated; with the arrangement of the liquid supplementing tank, the problem of catalyst loss caused by the fact that the catalyst splashes and is bonded on the inner wall of a reaction kettle and cannot be remained in the slurry when the catalyst is stirred at the high temperature is solved to a certain extent. Therefore, with the arrangement of the liquid supplementing tank, the catalyst activity is sufficiently exerted, unnecessary loss of the catalyst is avoided, and a finally measured result about influence of the catalyst on the reaction efficiency is more accurate.
