Abstract

The invention relates to a copper-based catalyst for synthesis of methanol in a slurry bed. The catalyst is characterized in that it is composed of active component CuO, ZnO and a carrier. Specifically, the catalyst consists of 30.0-70.0wt% of CuO, 10.0-50.0wt% of ZnO, and 5.0-20.0wt% of the carrier. The catalyst provided in the invention has the advantages of high activity, good stability and long life.

Description

technical field [0001] The invention belongs to a catalyst, a preparation method and an application, and in particular relates to a slurry bed synthesis gas methanol copper-based catalyst, a preparation method and an application. Background technique [0002] Coal gasification to methanol is one of the effective ways for efficient and clean utilization of coal. The traditional industrial production of methanol adopts a fixed-bed reaction process, which has disadvantages such as difficult temperature control, large gas circulation ratio, low single-pass conversion rate, and poor economic efficiency. Chemical Systems Inc. of the United States proposed the gas-liquid-solid three-phase slurry bed methanol synthesis process (LPMeOH) in 1975, which has the advantages of uniform reaction temperature and easy control, high single-pass conversion rate of CO, high energy utilization rate and low cost. It is especially suitable for synthesizing methanol from CO-rich coal gasification ...
