Improvement in the arsenate method for purification of coke gas from hydrogen sulfide. [Most important factors:(1) As/sub 2/O/sub 3/:H/sub 2/S ratio; when greater than or equal to 15, approx. 90% of H/sub 2/S extracted; (2) enrichment in O (30-5%) of air or of solution by addition of O-containing additives, i. e. quinone (0. 01% or less) during regeneration process; (3) continuity of neutralization of regeneration solution]

Purification of coke-oven gas by removal of CO/sub 2/ and H/sub 2/S with ethylamine. [Gas treated with Na arsenate solution and bog iron ore to remove most of H/sub 2/S; cycle gas then compresses and scrubs in series of towers with H/sub 2/O, C/sub 2/H/sub 5/NH/sub 2/, caustic, and H/sub 2/O again]
Production of hydrogen. [intimately mixing the finely divided carbonaceous material with water in a C:H/sub 2/O weight ratio of greater than or equal to 1:3; resulting mixture is heated at 640-90/sup 0/F at a pressure (approx. 5000 psig) sufficient to maintain the H/sub 2/O in the liquid state in the presence of a catalyst]
Removal of hydrogen sulfide from gas mixtures. [Coke-oven gas (6. 8g H/sub 2/S/m/sup 3/) washed with solution of alkaline salts equivalent to 12 kg Na/sub 3/PO/sub 4//m/sup 3/; 56 kg Na/sub 2/HPO/sub 4/, and 50 kg As/sub 2/O/sub 3/; purification is complete; precipitated As/sub 2/S/sub 3/ roasted to produce SO/sub 2/ and recover As/sub 2/O/sub 3/]
