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 ...
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.
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.

The objective of this work was to evaluate the applicability of commercial UOP hydrotreating and reforming processes to naphthas derived from the HCoal process. Three naphthas were studied. One was the primary naphtha generated from the HCoal syncrude operation. The other two products were from hydrocracking HCoal gas oil.
HCoal, a catalytic hydroliquefaction process developed by Hydrocarbon Research, Inc. for conversion of coal to highquality, clean liquids, has advanced to the stage of commercial evaluation with the construction in Catlettsburg, Kentucky of a 600 ton/day pilot plant which will produce up to 2,500 barrels per day of liquid product.
The main gas components produced in the process of coal oxidation and spontaneous combustion include CO, CO 2, CH 4, C 2 H 4, C 2 H 6, and C 2 H 2. Among them, coal reacts with oxygen at ordinary temperatures to produce CO, CO 2, and CH 4 as well as including coal analysis. In the part of the index gas detection experiment, the aforementioned ...
The coal conversion process to be used is the HCOAL process, which is in the pilot plant testing stage under the auspices of the US Department of Energy at the HCOAL Pilot Plant Project near Catlettsburg, Kentucky. The preliminary plans for the commercial plant are for a 18,140 metric ton/day ...
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 objective of this investigation is to evaluate the processability of the primary products of coal liquefaction generated by three ERDA sponsored processes: Synthoil, Solvent Refined Coal (SRC), and HCoal. The study entails actual bench scale processing of coal liquids and an indepth analytical characterization of charge and product streams.
Synthoil, HCoal, and Exxon donor solvent processes. Final report Feb 77Aug 78}, author = {Parker, C L and Dykstra, D I}, abstractNote = {This volume is an environmental characterization of three selected coal liquefaction systems: Synthoil, HCoal, and Exxon Donor Solvent. It documents and evaluates existing environmentally significant 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 ...
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.
The fluid dynamics occurring in HRI's Hcoal process development unit coal liquefaction reactor during Run PDU10 were measured and compared with Amoco Oil coldflow fluidization results. It was found that catalyst bed expansions and gas holdups are higher in the PDU than those observed in the coldflow tests for slurries having the same ...
The HCoal process generated coal derived liquids in which exposures to polynuclear aromatics (PNA) were a hazard at most phases. Other hazards were coal dust, fire, noise, aromatic amines, ammonia (), hydrogensulfide (), phenols, benzene (71432), toluene (108883), xylene (), and hydrocarbons. ...
The HCoal process, developed by Hydrocarbon Research, Inc., in 1963, mixes pulverized coal with recycled liquids, hydrogen and a catalyst in the ebullated bed reactor. The advantages of this process are that dissolution and oil upgrading take place in a single reactor, the products have a high H:C ratio and a fast reaction time, while the main ...
The Hcoal process of Hydrocarbon Research was developed in a 200 t/d plant in Catlettsburg (Kentucky). The main partners participating in this project were the DOE and Ashland Oil together with other energy com panies. Hydrogenation is conducted under relatively mild reaction condi tions of 455 and 210 bar with a cobalt/molybdenum catalyst.
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 ...
