Removal of carbon dioxide and hydrogen sulfide from gases. [Gases are washed with ammoniacal solutions containing salts that react with CO/sub 2/ and (or) give sparingly soluble crystalline precipitates, e. g. , NaCl and FeSO/sub 4/; equations NH/sub 3/ + H/sub 2/S = NH/sub 4/HS, FeSO/sub 4/ + NH/sub 4/HS = FeS + (NH/sub 4/)HSO/sub 4/; NH/sub 4/HSO/sub 4/ + NH/sub 3/ = (NH/sub 4/)/sub 2/SO/sub 4/]
Methane manufacture from carbon dioxide and hydrogen. [Gas of >15% CO/sub 2/ converted to CH/sub 4/ in 2 stages over Ni catalyst at 180-250/sup 0/ at atmospheric or elevated pressure; catalyst of 60% Ni, 30% kieselguhr, 10% MgO; CO/sub 2/--H conversion 84. 5% in 1st stage and 90% in 2nd or 98-9% total yield]
Removal of carbon dioxide and hydrogen sulfide from gas mixtures. [Gas mixture brought into contact with aqueous K/sub 2/CO/sub 3/ solution at more than 50, preferably 350, psig and above 200/sup 0/F, preferably 235/sup 0/F]
