Description: HZ-04A via network support protection agent is a high purity alumina as the main raw material, high temperature firing, it has high strength, high porosity, effective reaction column bearing the weight of the other bed, high porosity can effectively reduce the loss of pressure drop rate, while the bottom stream can effectively inhibit the recoil, the top layer of the catalyst bed up protection.
