Catalyst and its use for the manufacture of methane from gases containing carbon monoxide and dioxide and hydrogen. [preparation of nickel catalysts]

Patent ·
OSTI ID:6773067
; ; ; ; ; ;
An improved nickel catalyst from West Germany's BASF AG allows the production of methane from carbon monoxide, carbon dioxide, and hydrogen at a lower feedstock temperature of only 392/sup 0/ to 572/sup 0/F (200/sup 0/ to 300/sup 0/C). The catalyst is manufactured by precipitating the compound Ni/sub 6/Al/sub 2/(OH)/sub 16/CO/sub 3/ x 4H/sub 2/O from aqueous solution, drying it at a temperature of 176/sup 0/ to 356/sup 0/F (80/sup 0/ to 180/sup 0/C), calcining it at a temperature of 572/sup 0/ to 1022/sup 0/F (300/sup 0/ to 550/sup 0/C), and subsequently reducing it in a stream of hydrogen. Between the drying stage and the calcination stage, the temperature is raised at a rate of 3/sup 0/ to 6/sup 0/F (1.66/sup 0/ to 3.33/sup 0/C)/min.
