What are the selection criteria for nickel catalysts
Classification:
【Summary】At present, there are many nickel catalyst manufacturers in China, most of the small factories have weak technical strength and backward production process, and the quality of nickel catalyst products is greatly affected by human factors. Next, we will tell you the selection criteria for nickel-based catalysts. The quality control method of nickel-based catalyst is the activity test of the product, and there is still a lack of quality control of semi-finished products in the production process. Therefore, nickel catalyst users should choose those production process and equipment to win, product quality is stable, but also have the use of service conditions of the unit production of the best high-efficiency nickel catalyst. Generally, nickel catalysts with high activity, high load bearing, good strength, selectivity and good toxicity resistance should be selected.

The quality control method of nickel-based catalyst is the activity test of the product, and there is still a lack of quality control of semi-finished products in the production process. Therefore, nickel catalyst users should choose those production process and equipment to win, product quality is stable, but also have the use of service conditions of the unit production of the best high-efficiency nickel catalyst. Generally, nickel catalysts with high activity, high load bearing, good strength, selectivity and good toxicity resistance should be selected.
1. For example, if the current methanol synthesis nickel catalyst is selected, the CO conversion rate of other methanol synthesis nickel catalysts can be increased by 4%. When the CO in the fresh gas is 20-94%, the yield can be increased by 2783t/a, the output value can be 5 million yuan/a (calculated by 300 working days a year), and a large amount of steam can be increased at the same time.
2. Select the appropriate nickel catalyst type and model
Usually, the development of a specific type of nickel catalyst has its background and pertinence. Therefore, nickel catalyst users in the selection of nickel catalyst should be based on the specific production process conditions of the unit and the structural requirements of the catalytic reactor to select the nickel catalyst to match the factory operating conditions, otherwise it is easy to cause the deactivation of the nickel catalyst and the early termination of life.
3. Select the appropriate shape and size of the nickel catalyst
The relative volume of hydrodesulfurization activity of Co-Mo hydrofining nickel catalysts with different shapes decreases at different rates with the increase of particle size, so suitable shapes and sizes of hydrofining nickel catalysts should be selected for different raw materials.
