Light paraffins such as ethane, propane, butane, and pentane were converted to aromatic hydrocarbons such as benzene, toluene, and xylenes on Pt/H-ZSM-5 catalysts; the liquid product was mostly composed of the aromatic hydrocarbons. As the method of Pt supporting on H-ZSM-5, the ion-exchang...
Clays are a good natural resource of aluminium and silica in the economical synthesis of ZSM-5 for catalytic application21. Although there are many reports on the use of clays as Al/Si precursor, there has been little progress in directly producing the hieratical H form of ZSM-5 zeolites ...
