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