In order to improve the effect of the activated alumina carrier (AA), the following operations can be performed:
1. The strength index is very important for the actual use. Whether it is loaded into the reaction tank or the absorption tower, the poor strength of AA will cause the catalyst to pulverize, block the reaction pipeline, and reduce the recycling efficiency of the AA.
2. The catalyst made of a large pore volume AA has higher catalytic activity, selectivity and conversion rate than the small pore volume AA.
3. Maintain a reasonable distribution of pore volume. The catalytic reaction is mainly achieved through the developed inner surface of AA, that is, the reaction is carried out on the small pore wall of the AA. The catalytic reaction must be carried out completely.
1. First, make it easy for the molecules of the raw gas to enter the medium pores from the large pores and then the small pores. After the reaction, the molecules of the product move from the small pores and medium pores to the large pores.
2. The product is diffused from the macropores to the catalyst particles, so the larger the pore volume, the better the product. We should develop AA with a reasonable micropore distribution to improve its selectivity and conversion rate in the catalytic process.
Therefore, while pursuing a large pore volume for AA, we should pay attention to improving the mechanical strength of the carrier and paying attention to the reasonable distribution of pore volume, so as to better improve the performance of the product.
