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 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 .
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##

WEBThis work is similar in scope and intent to that completed under Contract DEAC0579ET14503, Development of the Correlation Between Slurry Oil Composition and Process Performance. That contract was devoted to the analyses of slurry recycle oils from the HCoal process development unit operated by HRI at Trenton, New Jersey.
WEBIn the process, the particulate coal is slurried with a processderived liquid solvent and fed at temperature below about 650° F. into a first stage alytic reaction zone operated at conditions which promote controlled rate liquefaction of the coal, while simultaneously hydrogenating the hydrocarbon recycle oils at conditions favoring ...
WEBThe development of diagnostic instrumentation for monitoring coal liquefaction process streams is discussed. A sapphire optical fiber was used as an attenuated total reflectance (ATR) element in conjunction with Fourier transform infrared (FTIR) spectrometry to probe harsh liquefaction process streams.

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 alysts are based on a unique substrate prepared in bead form from a rehydratable alumina. 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).
WEBOct 15, 2023 · 1. Introduction. As a traditional energy source, coal has long occupied an important position in the world energy system (Zhang et al., 2022).However, during the process of coal mining and utilization, coal spontaneous combustion (CSC) often occurs (Pan et al., 2023).CSC is widespread among the world's major coalproducing countries, .
WEBOct 1, 1984 · Process slurries emanating from reactors generally contain 5 to 10 wt.% of solids. Solid—liquid separation processes must be used to separate the mineral residue and unconverted carbon from liquefied coal. Difficulties in removing those solid components represent a major obstacle to economic production of liquefied coal products.
