An efficient methanol synthesis catalyst comprises the active components of copper, zinc, iron and silicone at the mass ratio of 1.2:1:0.7:(0.1-0.2). A preparation method for the catalyst comprises the following steps: preparing a solution by taking the copper, zinc, iron and silicone as materials according to the ratio; uniformly stirring and evaporating to obtain a saturated solution; performing temperature reduction and crystallization to generate mixture crystals; obtaining the catalyst through filtering, drying and processing the crystals into particles. The catalyst has relatively large and stable specific surface area, shows relatively high methanol space time yield and selectivity, and has relatively high thermal stability and low-temperature activity, and relatively wide operation temperature area.
Description
technical field [0001] The invention relates to a high-efficiency catalyst used for synthesizing methanol and a preparation method thereof, belonging to the technical field of catalysts. technical background [0002] Methanol is an important chemical basic raw material and clean liquid fuel, widely used in organic synthesis, dyes, medicine, pesticides, automobiles, national defense and other fields. With the development of methanol synthesis process, synthesis catalysts are also being continuously researched and improved. The zinc-chromium catalyst in the prior art has a long service life and a wide application range, but its activity is low. Copper-based catalysts are currently the most widely used catalysts for methanol synthesis. The invention is improved on the basis of the copper-based catalyst, and the obtained methanol synthesis catalyst can greatly improve the performance of the copper-based catalyst. Contents of the invention [0003] The object of the presen...
