During the production of activated alumina carrier, the effect of products produced by different technologies is different. In order to improve the use effect of activated alumina carrier, the following operations can be carried out:

1、 The strength index is very important for the actual use of the product, so it can improve the use strength. Whether it is loaded into the reaction tank or absorption tower, the strength difference of the carrier will make the catalyst powdered, block the reaction pipeline, and reduce the recycling efficiency of the carrier.

2、 Compared with the products with small pore volume, the catalysts with large pore volume have higher catalytic activity, selectivity and conversion.

3、 In order to maintain the reasonable distribution of pore volume, the catalytic reaction is mainly realized through the developed inner surface of the support, that is, the reaction is carried out on the small pore wall of the active alumina support, so that the catalytic reaction can be carried out completely.

1. The first step is to make the molecules of the feed gas easy to enter the mesopore from the macropore, and then enter the small hole. After the reaction, the molecules of the product move from the small hole, mesopore to the macropore.

2. Therefore, the larger the pore volume of the product, the better. We should develop the active alumina support with reasonable micropore distribution to improve its selectivity and conversion rate in the catalytic process.

Therefore, in the pursuit of large pore volume, we should pay attention to improve the mechanical strength of the carrier, and pay attention to the reasonable distribution of pore volume, so as to better improve the performance of the product.
