Abstract. A large coalliquefaction pilot plant is in operation at Catlettsburg, Kentucky, expanding on the HCoal technology. The pilot plant operated very successfully during 1981, confirming research yield data on eastern bituminous coal, demonstrating operability of the process, and resulting in a significant accumulation of engineering data.

The HCoal process was a starting basis for subsequent process development sponsored by the US DOE over about three decades time. A principal focus of this longterm project was RD of catalysts that were tolerant of, and would not be rapidly deactivated by, coalderived mineral matter in the reactor. Typical early catalysts showed rapid ...

Axens's HCoal process is also a twostage process (two catalytic reactors). Generally, the ICL process produces highcetane diesel and lowoctane naptha; the DCL process produces onspec diesel and highoctane naptha. (Headwaters points out the hybrid DCL/ICL process can produce premium gasoline and diesel fuel with minimal refining.)
