The effect of HF treatment on etherification activities of ZSM-5 zeolite was investigated.Appearance,crystal structure,pore structure,acid quality of treated zeolite was charactered.It was found that catalyst treated ...
Salen Mn(III)/MCM-48 catalyst was prepared and characterized by FT-IR,XRD,UV-Vis,and GC.The catalyst was evaluated by the epoxidation of styrene;remarkable activity and enantioselectivity were received.
SO42-/TiO2/Fe3O4 supporting Ni catalyst was synthesized via the sol-gel technology.It is a bifunctional catalyst that could be employed in both metal catalytic and acid catalytic processes and separated by magnetic fi...
The 4% Ni-Al2O3catalysts prepared by coprecipitation method calcined at different temperature was tested by propane selective catalytic reduction of nitric oxide(NO) in excess oxygen.Catalyst calcined at 550 ℃ show...
High titanium loading MCM-41 was prepared via the novel post-grafting method by impregnating calcined MCM-41 into the Ti-Si sol.In comparison with the conventional direct synthesis and the impregnation method,the regu...
