$34 million 5 TPH (ton/hr) Bi-Gas pilot plant, completed for Bituminous Coal Research Inc. in 1976 by Stearns-Roger Inc., is a grassroots facility near Homer City, Pa., designed to pulverize 1.5 in x 0 size coal to 80% minus 200 mesh to be slurried in water (60% solids) and sprayed into a hot gas recycle stream that dries and transports the coal particles to a cyclone elevated for gravity feed into a stream of synthesis gas entering Stage II of the gasifier, where at 2200/sup 0/F the coal is partially converted to methane and synthesis gas. Char separated from Stage II gas in a cyclone is injected with oxygen and steam into Stage I where the char is completely gasified at 2700/sup 0/ to 3000/sup 0/F under slagging conditions with ash removal as quenched, shattered slag. Raw gas is cleaned and shifted to the proper H/sub 2//CO ratio, freed from hydrogen sulfide and carbon dioxide in a Selexol unit, and passed through a fluid-bed catalytic methanation system. After a final Selexol treatment to removh the coal micropores; the advantages of supercritical gas oveeatere integrated closely with MS or GC/MS. These trapped compounds are believed to be products and residuals of the original coalificans towards a more compl features displaying 'wave-like' and 'fork-like' shapes.
