The present study deals with the modification of mordenite (HMOR) and ferrierite (HFER) zeolites by nickel. XRD, XRF, nitrogen adsorption, TPR, XANES, EXAFS were used to thoroughly characterize the materials. The metal level was set to 1wt% for all catalysts and nickel was introduced by cationic exchange following either conventional thermal heating or in the presence of microwave radiation (HFER)...
Carbided molybdenum catalysts supported on ultrastable Y zeolites were prepared by adsorption of molybdenum hexacarbonyl vapors at 343K or wet point impregnation with ammonium heptamolybdate solutions, followed in both cases by temperature-programmed carburization under a 20% methane in hydrogen mixture up to 923K. Nitrogen physical adsorption and X-ray diffraction clearly established that the zeolite...
