This product has been developed for many years and now has a series of products with bulk density ranging from 0.3---0.7g/cm 3 and pore volume ranging from 0.5---1.5 ml/g. According to the different needs of users, we can produce the required Alumina carrier, new and old users are welcome to jointly develop. Different catalysts have requirements for the required carriers which are characteristics of the catalyst industry. Our company has mastered the means to control the physical and chemical properties of carriers, changes process conditions according to user needs, and develops or trial-produces low-sodium alumina carriers of different pore sizes and different particle sizes for users. We hope that with the support of new and old users, our company will have more varieties of activated alumina appear on the market.
