Bifunctional catalysts consisting of platinum supported on various types of zeolites (viz. beta, mordenite, USY, ZSM-5 and ferrierite) were prepared by using an incipient wetness impregnation method to obtain a 0.5wt.% metal load. A beta zeolite sample was dealuminated with nitric or oxalic acid to obtain solids that were used as catalytic supports. The catalysts thus obtained were characterized by...
The isomerization of n-hexane on MoO 3 leads to the formation of a new catalytically active phase, molybdenum oxycarbide, that exhibits high and stable activity and isomer selectivity with time on stream under soft reaction conditions. The study as a function of the reaction temperature shows that too low a temperature prevents the MoO 3 transformation, while too high a temperature...
