ABSTRACT:

Preliminary scoping evaluations of ten conceptual coal liquefaction processes were made for the Department of Energy using available published information. Production costs calculated under a consistent set of economic criteria varied from $0.78 to $1.47/gal for gasoline in constant 1979 dollars. However, existing design documents showed little consistency as to status of process development, credibility of process design basis, completeness of design, or conservatism of cost estimation. We concluded that a more complete and thorough design study of each process would be necessary to achieve any degree of technical and economic consistency, and that it was therefore not possible to satisfy DOE's desire for consistent technical and economic comparisons in this type of preliminary scoping study.
