CATALYTIC REACTION OF CO 4 WITH CH 4 OVER NICKEL CATALYST.

The reaction between CO2and CH4was carried out in a fixed-bed continuous flow reactor over y-alumina supported nickel metal, reaction temperature was 773-1073°K and reaction pressure 0.1-0.13MPa with different ratios of CH4C02. Catalysts were characterized by SEM, XRD, XPS and IJTA. It was found that Ni/y-alumina had higher activity, selectivity and stability when it was made in strong acid(pH⩽2) or strong base (pH⩽ll) solution. In this reaction syngas with lower ratios of H2/CO was produced. [ABSTRACT FROM PUBLISHER]
