| Abstract: | When using spray drying process to produce super - stabilization zeolite, the contraction of crystal size is the major quality problem faced by domestic catalyst manufacturer. Solely depending on increasing temperature in spray - drying process could lead to destruction of crystal structure and reduction in crystallization maintenance. In conjunction with hydrothermal chemistry in super-stabilization of zeolite, analyzes the effects of spray drying on calcinating quality and presents some measures for optimization, ensuring the quality specifications of super-stabilization zeolite. |
