When the activated alumina carrier is produced, the effects of the products produced by different technologies are also different. In order to improve the use effect of the activated alumina carrier, you can operate from the following items:
1. The strength is very important to the actual use of the product, so it can improve the strength of use. Whether it is installed in a reaction tank or an absorption tower, the poor strength of the carrier will powder the catalyst, block the reaction pipeline, and reduce the efficiency of carrier recycling. .
2. The large pore volume carrier in catalyst has higher catalytic activity, selectivity and conversion rate than the small pore volume activated alumina carrier product.
3. To maintain a reasonable distribution of pore volume, the catalytic reaction is mainly realized through the developed inner surface of the carrier, that is, the reaction is carried out on the small pore wall of the activated alumina carrier, and the catalytic reaction must be completed.
1. Firstly, the molecules of the raw material gas must easily enter the mesopores from the large pores and then into the small pores. After the reaction proceeds, the molecules of the product move from the small pores and mesopores to the large pores.
2. The particles that diffuse from the macropores to the catalyst become products, so the larger the pore volume, the better the product. An activated alumina carrier with reasonable micropore distribution should be developed to improve its selectivity and conversion rate in the catalytic process.
Therefore, while the activated alumina support pursues large pore volume, attention should be paid to improving the mechanical strength of the support and the reasonable distribution of pore volume, so as to better improve the performance of the product.
