Hydrogasification of pretreated coal for pipeline gas production

Journal Article · · Adv. Chem. Ser.; (United States)
Lightly pretreated high volatile bituminous coals were hydrogasified with hydrogen-steam and hydrogen-methane-steam mixtures in a continuous-flow pilot unit. Tests at 1000 psig and between 1200 to 1900/sup 0/F simulated in sequence a two-stage countercurrent system, operated both as free fall and moving bed. Experiments were aimed at maximizing hydrogen utilization and controlling carbon conversion so that after hydrogasification enough carbon remains to generate hydrogen in the over-all process. The raw gas produced has a heating value of about 700 Btu/std cu ft, which can be upgraded by purification and cleanup methanation to over 900 Btu/std cu ft.
