WEBThe Shenhua CTL plant became operational in 2008, reportedly producing 20,000 barrels a day of diesel oil, liquefied petroleum gas and naphtha. The plant relies on the HCoal process developments started in the 1950s, to mix pulverized coal with recycled liquids, hydrogen and a alyst in a bubbling reactor to create synthetic fuels and other ...
WEBThe HCoal Process was invented by HRI, and has been under development for over 15 years. The program was initially funded by Dynalectron Corporation, the parent company of HRI and by the Office of Coal Research and Atlantic Richfield Company. Currently the sponsors are the Department of Energy, the Electric Power Research Institute, Ashland ...

WEBThe 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 alyst bed expansions and gas holdups are higher in the PDU than those observed in the coldflow tests for slurries having the same nominal .
WEBThe objective of the work reported herein was to develop the capital costs and the product costs for an HCoal liquefaction facility, using the most recent yield data from HRI's PDU unit for Illinois and Wyodak coals. A key part of this effort was the development of a processing configuration for each of the two cases in order to provide selfsufficient .

WEBTheir 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 alysts that are ...
WEBHRI has developed a alyst regeneration procedure for spent alysts 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 alysts from the HCoal Process were either ...
WEBFor this coal a 17% increase in cyclohexane solubles, a 12% increase in toluene solubles and a 1 to 3% increase in the THF solubles, are observed for the present process over the HCoal® process. Thus, the present process is effective in converting a high rank, medium volatile bituminous coal to solubles and hydrocarbon liquid products. ##STR4##
