Pore volume and specific surface area are the main goals when describing the activity characteristics of activated alumina. In general, it is thought that the activity is high when these two factors are high. The activities has attracted more people's attention. To ensure and enhance the activity of activated alumina, the preparation of materials, the quantity of materials during molding, the choice of additives, the molding process, drying, and activation roasting processes are typically all closely regulated.
The support of a catalyst has a major bearing on its selectivity. Therefore, it is frequently required to discuss the selectivity of catalysts supported by activated alumina while discussing the activity of activated alumina. because the support directly affects the activity and selectivity of the catalyst. The selectivity of a catalyst is directly correlated with the distribution of its pores, and the distribution of the catalyst's pores is correlated with that of the support. As a result, the pore size dispersion of the activated alumina as a carrier must be appropriate.
