Title: Effect of product upgrading on Fischer-Tropsch indirect coal liquefaction economics

Abstract

Conceptual plant designs with cost estimates for indirect coal liquefaction technology to produce environmentally acceptable transportation liquid fuels meeting the Clear Air Act requirements were developed for the US Department of Energy (DOE). The designs incorporate the latest development in coal gasification technology and advanced Fischer-Tropsch (F-T) slurry reactor design. ASPEN process simulation models were developed to provide detailed plant material and energy balances, utility requirements, operating and capital costs. A linear programming model based on a typical PADD II refinery was developed to assess the values of the produced F-T products. The results then were used in a discounted cash flow spreadsheet model to examine the effect of key process variables on the overall F-T economics. Different models were developed to investigate the various routes of upgrading the F-T products. The effects of incorporating a close-coupled ZSM-5 reactor to upgrade the vapor stream leaving the Fischer-Tropsch reactor have been reported previously. This paper compares two different schemes of F-T was upgrading, namely fluidized bed catalytic cracking verse mild hydrocracking.
