Supported KVO3 catalysts were prepared by impregnating different kinds of supporters (α-Al2O3, γ-A12O3 and SiO2 powders) with a KVO3 solution. The activity of
Thermal cracking of hydrocarbons for olefin production is normally carried out in long reactor tubes suspended in a large gas fired furnace. In this paper, a co
The effects of the initial framework SiO2/Al2O3 ratio and temperature on the structural changes of NaY zeolites during hydrothermal treatments are studied. Two
For investigating the effect of dealumination on the pore structure and catalytic performance, ZSM-5/Y composite zeolites synthesized in situ from NaY gel were
The interactions between the components of FeCl3-Al (i-Bu)3-bipyridine -catalyst were studied by the electric conductivity of these components in a hydrogenated
