【摘要】：以不经任何处理的微硅粉作为硅铝源,固相合成ZSM-5分子筛,考察晶化温度、晶化时间、微硅粉用量、模板剂用量、氯化铵用量等因素对合成分子筛的影响。采用XRD、XRF、IR、SEM、等手段进行分析表征。结果表明最适宜的合成条件:晶化温度为160℃,晶化时间为24 h,按n(TPABr)∶n(NH_4~+)∶n(SiO_2)∶n(H_2O)=0.10∶0.90∶1.00∶4.60,称取适量模板剂、氯化铵、微硅粉和微硅粉。该法合成的ZSM-5分子筛结晶度高、晶形完备、具有丰富的孔结构、较大的比表面积和优良的热稳定性,可以作为工业催化剂和吸附剂使用。
[Abstract]:ZSM-5 molecular sieve was synthesized by solid phase synthesis using microsilica powder without any treatment. The effects of crystallization temperature, crystallization time, the amount of microsilica powder, the amount of template and ammonium chloride on the synthesis of molecular sieve were investigated. XRD,XRF,IR,SEM, and other methods were used for analysis and characterization. The results show that the optimum synthesis conditions are as follows: crystallization temperature 160 鈩，
