没有使用模板, ZSM-5/MOR co 水晶的沸石被综合。沸石的物理化学的性质被 XRD,英尺红外, SEM 和 TPD 描绘然后与一个模板与 co 水晶的沸石相比综合了。分析结果显示他们在结构和作文是类似的。合成上的影响 ofpH 价值和 Si/AI 比率被学习。高 pH 价值或低 Si/A1 比率能为 mordenite (粗腐殖质) 提供更好的环境,这被发现结晶化。沸石在为生产乙烯和丙烯的催化裂开显示出的石油作为催化剂适用有到达 55 m% 的乙烯和丙烯的全部的收益的突出的催化性能。当催化剂包含了粗腐殖质的 5 m% 时,这个过程能完成很有利的效率。
A ZSM-5/MOR co-crystalline zeolite was synthesized without using the template. The physico-chemical properties of the zeolite were characterized by XRD, FT-IR, SEM and TPD and then compared with the co-crystalline zeolite synthesized with a template. Analytical results indicated that they were similar in structure and composition. The influences ofpH value and Si/Al ratio on synthesis were studied. It was found that a high pH value or a low Si/AI ratio could provide better environment for mordenite (MOR) crystallization. The zeolites applied as catalysts in naphtha catalytic cracking for producing ethylene and propylene showed outstanding catalytic performance with the total yield of ethylene and propylene reaching 55 m%. The process could achieve most favorable efficiency when the catalyst contained 5 m% of MOR.
