- 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.
-
1.
Koppers-Totzek suspension gasification
-
2.
U-GAS™ fluidized-bed gasification
-
3.
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:
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. -
