As part of a study for the conversion of coal to fluid fuels, we have developed three process designs for the conversion of Montana subbituminous coal to hydrogen based on three different gasifier technologies: Koppers-Totzek suspension gasification, U-GAS fluidized-bed gasification, and Fluidized Steam-Iron Process. For comparison with methane from coal, a fourth design, based on the HYGAS Process has been prepared. Nominal plant capacities are 250 billion Btu/day of product gas. Overall plant efficiencies for conversion of coal to major gaseous products plus by-products are: Koppers-Totzek, 57.0%; U-GAS, 66.4%; Steam-Iron, 62.6% (includes 18% by-product electricity); HYGAS, 74.0%. Product liquefaction requirements are presented. Capital and operating costs (mid-1974) are presented for U-GAS and HYGAS. With coal at $0.30/million Btu, prices for hydrogen and methane are $2.17 and $1.77/million Btu. Methane is more attractive in both efficiency and cost.
