By dilute sulphuric acid and sodium silicate solution through a step by step response and polycondensation generated through the granulation unit injection gel particles, the gel particles and then through acid soaking, washing, aging, secondary acid soaking, dry, get macroporous spherical silica gel products.
Drying process is second acid bubbles of the gel out grain after drying drying equipment 500-950 ℃. As a result of acid soaking process, reduced metal ions remain in the silica gel pores, followed by high temperature treatment, remain in the silica gel void volatile acids decomposition or burning in, so no residue in macroporous silica gel improves as the catalytic activity of the catalyst.
