Low-energy process for separating hydrogen and methane in advanced coal-gasification processes. Final report, September 8, 1980-January 7, 1983
This report contains the detailed results of the following three-part study: Part I. Adsorption of H/sub 2//CH/sub 4/ from single and mixed gases on activated carbon, coals and chars; Part II. Adsorption of H/sub 2/S and its mixtures with H/sub 2//CH/sub 4/ on activated carbon, coals and chars; and Part III. Separation of H/sub 2//CH/sub 4/ and H/sub 2//CH/sub 4//H/sub 2/S mixtures by a temperature-cycling process. The original scope of the study, as indicated by the title of the report, has been expanded to include H/sub 2/S in the gas mixture. The inclusion of H/sub 2/S was to study the feasibility of combining the H/sub 2//CH/sub 4/ separation step with the H/sub 2/S removal step into a single process. The success of the feasibility study naturally leads to the possibility of separating both CO/sub 2/ and H/sub 2/S from H/sub 2/ and CH/sub 4/ in coal gasification products by the cyclic adsorption/desorption process. The results of the study are presented.
