Exploratory research on novel coal liquefaction concept. [Quarterly report], May 24--September 30, 1995

PDF Version Also Available for Download.

Description

CONSOL Inc., the University of Kentucky/Center for Applied Energy Research (CAER), and LDP Associates are conducting a three-year research program to explore the technical and economic feasibility of a novel direct coal liquefaction concept. The purpose of this research program is to explore a new approach to direct coal liquefaction in which the primary coal dissolution step is effected by chemical rather than thermal cleavage of bonds in the coal. This is done at a temperature which is significantly lower than that typically used in conventional coal liquefaction. Reaction at this low temperature results in high conversion of the coal ... continued below

Description

CONSOL Inc., the University of Kentucky/Center for Applied Energy Research (CAER), and LDP Associates are conducting a three-year research program to explore the technical and economic feasibility of a novel direct coal liquefaction concept. The purpose of this research program is to explore a new approach to direct coal liquefaction in which the primary coal dissolution step is effected by chemical rather than thermal cleavage of bonds in the coal. This is done at a temperature which is significantly lower than that typically used in conventional coal liquefaction. Reaction at this low temperature results in high conversion of the coal to a solubilized form, with little hydrocarbon gas make, and avoids the thermally induced retrograde reactions which are unavoidable in conventional thermal processes. In addition, for low-rank coals, a substantial portion of the oxygen in the coal is removed as CO and CO{sub 2} during the dissolution. The higher selectivity to liquid products and rejection of oxygen as carbon oxides should result in improved hydrogen utilization. The basis of the novel concept is the discovery made by CONSOL R&D that certain hydride transfer agents are very active for coal dissolution at temperatures in the range of 350{degree}C. Because of the exploratory nature of the research, the project is divided into sequential tasks that are designed to first evaluate key elements of the process is presented for the following tasks: management plan; evaluation of process steps; engineering and economic study and reporting.
