REACTION OF CO2 AND H2 IN THE PRESENCE OF CO AND NI CATALYSTS

The activity and selectivity of 10 % Co/support and 10 96 Ni/support c atalysts (where the support is Al2O3, SiO2, C) in the synthesis of hyd rocarbons from CO2 and H-2 were studied. The extent of conversion of t he starting mixture and the yield of methane were shown to depend on t he composition of the catalytic system. Cobalt catalysts with various types of carbons as supports am the most active, They permit the synth esis of methane in yields up to 70 % of the theoretical value.
