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.
Interim report for HRI HCoal}, author = {Peters, B. C.}, ... This document contains the results of an investigation to determine the suitability of the FMC COED Pyrolysis Process Western Kentucky Syncrude as a petrochemical feedstock. A sample of the whole crude was distilled into four straight run fractions: IBP350/sup 0/F naphtha, 350650 ...
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 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/US DOE and a large group of oil companies (DOE, 2015b; Xinjua News, 2014). Very few DCL programs were ...
Under DOE Contract DEAC0577ET10152, HRI is investigating the thermal dissolution of coal and its effects on the mechanism of catalytic 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 the liquefaction reactor which can be ...
The project was initiated in 1965 under the Office of Coal Research, US Department of Interior Contract No. with Hydrocarbon Research, Inc., and was completed under US Department of Energy Contract No. DEAC0576ET10143 with Ashland Synthetic Fuels, Inc. Data generated by HRI's Bench Scale and 3ton per day Process Development ...
The operability of the HCoal Process was clearly demonstrated and it has been concluded that the process is feasible for scale up to Pilot Plant size. As a result of PDU operations. HRI concluded that hydroclone systems can be operated to increase the residuum concentration in the reactor, and that the higher concentration will permit ...

Coalderived materials from experimental runs of Hydrocarbon Research Incorporated's (HRI) catalytic twostage liquefaction (CTSL) process were chemically characterized and screened for microbial mutagenicity. ... For these investigations, a blend of light and heavy HCoal process oils was fractionally distilled into 50/sup 0/F boiling point cuts.

The HCOAL Process is the direct catalytic hydroliquefaction process for converting coal into highquality, clean hydrocarbon liquids. ... The work includes modifications to HRI`s existing 3 ton ...
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 ...
A preliminary design for CTSL of Illinois deepcleaned coal was developed based on demonstrated benchscale performance in Run No. 22747(I27), and from HRI's design experience on the Breckinridge Project and HCoal/reg sign/ Process pilot plant operations at Catlettsburg.

Their spherical shape, crush strength, and abrasion resistance seem ideally suited for the ebullated bed reactors used in the HCOAL process developed by Hydrocarbon Research, Inc. (HRI). The beads have internal pore structures that are controllable over a wider range than conventional alumina supports, leading to active catalysts that are ...
HRI has developed a catalyst regeneration procedure for spent catalysts from both coal liquefaction and heavy petroleum residual upgrading operations to remove carbonaceous matter as well as most of the metal contaminants by chemical treatment. Test results show that activities of the regenerated catalysts from the HCoal Process were either ...
