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 ...

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.)

Introduction. H 2 S is a colorless, highly toxic gas with an unpleasant odor. The Chinese "Coal Mine Safety Regulations" states that the H 2 S concentration of coal mine gas is considered abnormal if it concentration is greater than ppm 1 concentrations present a serious threat to life and property in well mines due to the risk of H 2 S outburst 3 6.

Pulverized coal is mixed with recycle slurry oil to form a coaloil slurry. This slurry is passed through a heater into the lower part of the reactor. H is added, and the oil and H pass up through a bed of catalyst or activated Al/sub 2/O/sub 3/ at sufficient velocity to maintain an ebullated bed of catalyst or inert solids.

Maintenance management is an essential part of effective operation of a coal preparation plant. The key metric is: overall equipment effectiveness can be applied to any coalprocessing facility to measure and sustain performance. The maintenance management system consists of a framework of 3M: man, machine and methods.

The HCoal Process The HCoal process liquifies coal to either boiler fuel or synthetic crude in the presence of an added particulate catalyst. To produce synthetic crude instead of boiler fuel, more hydrogen is added to the slurry and reactor residence times are increased. It was developed by Hydrocarbon Research, Inc. (HRI) and was selected ...
