以Bi-Pt/H-mordenite为催化剂,对甘油(GLY, Glycerol)选择性氧化制备二羟基丙酮(DHA, Dihydroxyacetone)进行了研究。采用BET对催化剂进行表征,结果表明,催化剂的比表面积对催化剂的反应性能影响较小。甘油的裂解是主要的副反应,而H-mordenite可以抑制甘油的裂解,提高DHA的选择性。最佳反应条件为温度353 K,反应时间2~4 h,空气流量20 ...
Improvement of Lifetime of Ni/Mordenite Catalysts for CO2 Reforming of Methane by Support Modification with Alumina and Co-K Loading
Methane dry reforming Nickel cobalt potassium catalyst Mordenite, Alumina
2009/7/27
To improve the lifetime of catalysts for CO2 reforming of methane, Ni/H-mordenite catalyst was modified, which has high performance for the reaction. The unmodified catalyst was deactivated due to co...
THE TRANSFORMATIONS OF 4-tert-BUTYLTOLUENE OVER Ce-MODIFIED MORDENITE ZEOLITES
4-tert-butyltoluene tert-butylation isomerization dealkylation mordenite zeolites
2010/8/11
The transformation of 4-tert-butyltoluene over Ce-modified H-mordenite with 1 and 4 wt. % of cerium on zeolite prepared by Ce-impregnation of H- mordenite (H-MOR CBV 21A) was studied at 180 °C in the ...
