            WYA-2516 & 2517 Carrier series

            1. Chemical formula: Al2O3·nH2

            2. Properties and uses:

            This series of products is γ-form aluminum, which is used as catalyst carrier for the production of ethylene form ethanol. It has the advantages of stable specific surface area, suitable pore structure, high crushing strength, low content of impurities, etc. The series of products can effectively solve the problem of high reaction temperature, low ethanol conversion and ethylene selectivity, and short catalyst life. It can be processed into different shapes and specifications of the catalyst carrier according to the requirements of users.
