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.)

HCoal Syncrude product streams, prepared from Illinois No. 6, Wyodak, or West Kentucky No. 11 coal were obtained from the HCoal Process Development Unit (PDU) and analyzed for physical properties, elemental compositions, trace metal levels, and molecular composition. The trace metal levels are generally low in all except the heavy fuel oils.

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 ...

The HCOAL process was developed by HRI Company from the fluidizedbed heavy oil hydrocracking process (HOil). The process utilizes a fluidized bed catalytic reactor which has the reaction temperature range of 425 to 455°C, having the pressure of 20 MPa where the catalyst is aluminate extruded bar with alumina as the carrier. The inner part ...

The HCoal process is a development of Hydrocarbon Research, Inc. (HRI). It converts coal by catalytic hydrogenation to substitutes for petroleum ranging from a low sulfur fuel oil to an all distillate synthetic crude, the latter representing a potential source of raw material for the petrochemical industry. The process is a related application ...
