Optimize the production process of shape selective molecular sieve by resource utilization
In this paper,a new recycling process was designed,which mixed the mother liquor which affected the quality stability of the shape-selecting molecular sieve and the silicon-containing mother liquor which could not be fully recycled with NaY.Using the silica-aluminum adhesive as an aluminum source,the shape selection molecular sieve with stable quality and low production cost was synthesized by adjusting the silica-aluminum ratio,crystallization parameters and alkali-silicon ratio,which reduced the effluency of silica-containing wastewater and improved the utilization rate of NaY silicon.
