Greatly increased yields of aromatics were obtainied in the reaction of ethanol over ZSM-5 zeolites if the protonated catalyst was pretreated in aqueous mineral acids or if hydrogen choloride or dichloroethane was added to the feed. The treated catalysts apparently contained less sodium than the ammonium-exchanged catalysts, and in some cases, some ...

Kinetic regularities of CO oxidation at Co-Pd/ZSM-5 zeolite catalyst were investigated. Kinetic schemes accounting for formation of intermediate compounds at a surface layer due to adsorption of oxygen in molecular or (and) atomic forms were analyzed. It was proved that revealed kinetic dependences of reaction rate on concentration of reagents can be ...

การผลิตซีโอไลต์ชนิด ZSM-5 ละเอียดพิเศษจากกากของเสีย : รายงานวิจัยฉบับสมบูรณ์
2004สังเคราะห์ซีโอไลต์ชนิด ZSM-5 โดยใช้เถ้าแกลบเป็นแหล่งของซิลิกาเพื่อศึกษาตัวแปรที่มีผลต่อขนาดของซีโอไลต์ชนิด ZSM-5 ในขั้นแรกเป็นการเตรียมเถ้าแกลบ โดยการนำเถ้าแกลบไปต้มกับกรดไฮโดรคลอริกความเข้มข้น 1 โมลาร์ หลังจากนั้นนำแกลบไปเผาด้วยเตาภายใต้บรรยากาศออกซิเจนที่อุณหภูมิ 700 องศาเซลเซียส เป็นระยะเวลา 60 นาที ได้เถ้าแกลบที่มีองค์ประกอบเป็นซิลิกาบริสุทธิ์ 99.7%
