The HCoal process, developed by Hydrocarbon Research, Incorporated (HRI), involves the direct catalytic hydroliquefaction of coal to lowsulfur boiler fuel or synthetic crude oil. The HCoal ebullated bed reactor contains at least four discrete components: gas, liquid, catalyst, and unconverted coal and ash.
HRI is investigating the thermal dissolution of coal and its effects on the mechanism of coal liquefaction in an HCOAL system. The twostage coal liquefaction system consists of a coal slurry preheater which is essentially a short residence time reactor and a liquefaction reactor which can be regarded as a catalytichydrogenationreactor.
The HCoal® line of services converts coal directly into liquid fuels. Coal conversion typically reaches 95%. It provides a typical yield of four to five barrels of oil per ton of coal on a moisturefree basis including coal gasification that supplies hydrogen. The major products are: high naphthenic naphtha, diesel fuel with good cold [.]

Results of an investigation to determine the suitability of the HRI HCoal Syncrude as a petrochemical feedstock are reported. A sample of the whole crude was distilled into four straight run fractions; IBP350/sup 0/F naphtha, 350550/sup 0/F middistillate, 450800/sup 0/F vacuum gas oil, and 850FBP/sup 0/F resid.

In pyrolysis processes, the H/C ratio of coal is raised by rejecting carbon. The liquid products have little value, but pyrolysis is used on a massive scale to turn coal into coke for metallurgy, especially steelmaking. The coking process involves heating coal in closed vessels to very high temperatures (up to 2,000°C) in the absence of oxygen.
The most important process of this group is the HCoal process, developed by Hydrocarbon Research, Inc. (HRI) as an outgrowth of previous work on the hydrogenation of petroleum fractions. The development of this process was sponsored by ERDA and a large group of oil companies [1]. HCoal Processes

A key feature of the Hcoal process is the use of an ebullated bed for achieving good mixing between slurried coal, hydrogen, and extruded catalyst particles. The Hcoal reactor can be modeled as a fourphase fluid bed system containing liquid, fines, gases, and catalyst particles. In order to study the hydrodynamic behavior of this gas/slurry ...
OVERVIEW OF COALTOLIQUIDS: A HISTORICAL PERSPECTIVE HCoal Process In the early 1960s, HRI, now HTI, invented the HCoal process. This is a singlestep direct catalytic hydrogenationbased coal liquefaction process. Pulverized coal is converted at elevated temperature and pressure to liquids and gases that are then separated and ...
