WEBOVERVIEW OF COALTOLIQUIDS: A HISTORICAL PERSPECTIVE HCoal Process In the early 1960s, HRI, now HTI, invented the HCoal process. This is a singlestep direct alytic hydrogenationbased coal liquefaction process. Pulverized coal is converted at elevated temperature and pressure to liquids and gases that are then .
WEBThe HCoal process is a development of Hydrocarbon Research Inc. (HRI). It converts coal by alytic 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 appliion to HRI's HOil .

WEBIn the 1920s the FischerTropsch process was developed to convert the main constituents of the gas, hydrogen and carbon monoxide to liquid fuels. At the beginning of the 20th century the direct liquefaction process was first done by reacting coal with hydrogen and process solvent at high temperatures and pressure to produce liquid fuels.
WEBAlkylphenols constitute up to 20% of the products from such direct liquefaction processes as HCoal, solventrefined coal (SRC), and the Exxon donor solvent (EDS) process. According to Huibers, the Dynaphen process is a direct extension of HRI's hydrodealkylation process for the conversion of alkylaromatics to benzene and fuel gases.
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 .
