Title: Production of low-cost hydrogen. Final report, September 1989--August 1993

Significant technical progress has been made over the last decade to develop efficient processes for upgrading coal resources to distillable hydrocarbons which may be used to displace petroleum-derived fuels. While several different direct coal liquefaction routes are under investigation, each of them have in common the need for large quantities of hydrogen to convert the aromatic coal matrix to liquid products in the normal distillation range, and for hydrotreating to improve liquid product quality. In fact, it has been estimated that the production, recovery, and efficient use of hydrogen accounts for over 50 percent of the capital cost of the liquefaction facility. For this reason, improved methods for producing low-cost hydrogen are essential to the operating economics of the liquefaction process. This Final Report provides an assessment of the application of the MTCI indirect gasification technology for the production of low-cost hydrogen from coal feedstocks. The MTCI gasification technology is unique in that it overcomes many of the problems and issues associated with direct and other indirectly heated coal gasification systems. Although the MTCI technology can be utilized for producing hydrogen from almost any carbonaceous feedstock (fossil, biomass and waste), this report presents the results of an experimental program sponsoredmore » by the Department of Energy, Morgantown Energy Research Center, to demonstrate the production of hydrogen from coal, mild gasification chars, and liquefaction bottoms.« less
