Abstract

The synthesis of hydrocarbons from CO and H/sub 2/ on a Co-MgAl/sub 2/O/sub 4/ catalyst was studied at 190/sup 0/C under ambient pressure. The introduction of Al/sub 2/O/sub 3/ in the Co-MgAl/sub 2/O/sub 4/ catalyst reduces methane yield; the addition of 10 to 30 wt.% MgO increases activity. The catalyst 10 Co-6 MgO14 MgAl/sub 2/O/sub 4/ is the most active in this reaction. Carbon monoxide was demonstrated to undergo chemisorption on this catalyst mainly in weakly combined forms with desorption temperatures of 150/sup 0/ to 275/sup 0/C.
