ACTIVE ALUMINOSILICATE MATERIAL AND PREPARATION METHOD THEREFOR

摘要

An active aluminosilicate material and a preparation method therefor, the preparation method comprising: kneading a natural Si-Al mineral raw material, an alkali metal hydroxide and water, performing extrusion forming, and performing sub-molten salt activation treatment at a temperature of 150oC - 300oC to obtain the active aluminosilicate material. The obtained active aluminosilicate material may act as a highly active Si-Al source for the synthesis of a zeolite. The preparation method reduces the requirements of an activation process with regard to a device, is simple and easy, and has low material consumption and low energy consumption. The "three wastes" are not discharged, and the Si-Al ratio of the product is adjustable.
