The cobalt catalysts (cobalt content by weight: 7% 10% and 15%) and cobalt-nickel bimetallic catalysts (cobalt-nickel content by weight: 3.5%-3.5% 5%-5% and 7%-7%) were studied in dry reforming of methane for hydrogen and syngas production. All catalysts were synthesized by the wetness impregnation method. The dry reforming of methane was carried out at 700oC atmosphere pressure using a mixture; CH4 and CO2 in ratio 1:1. The result showed that the good activity and stability depend on metal content in catalysts and the combined 2 metals as bimetallic catalysts. The optimum amounts of catalysts are 10wt% Co for mono-metallic catalysts 75%CH4 and 75%CO2 conversion and 7wt% Ni-7wt% Co for bimetallic catalysts 87%CH4 and 89%CO2 conversion.

Dehydration of ethanol to ethylene was investigated over Mn- and Ni-containing mordenites. The synthesized catalysts were characterized by X-ray powder diffraction (XRD) infrared spectroscopy (FT-IR) BET method and temperature programmed desorption of ammonia. The performances on dehydration of ethanol to ethylene for these catalysts were compared at temperature range 250-450°oC WHSV (weight hourly space velocity) of 1 h-1 time on stream of 30-240 min and catalyst weight of 1.0 g. The results showed that conversion of ethanol of the Mn-MOR and Ni MOR was quite similar but selectivity to ethylene of the Mn-MOR catalyst was much higher. The Ni-MOR showed high selectivity to ethane due to its hydrogenation ability.
