WEBIn 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.
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, .
WEBAbstract. Hydrocarbon Research, Inc. (HRI) has completed the first one and onehalf years of a two year study for the Department of Energy (DOE) under Contract No. DEAC2285PC80002 for the development of a ''Low Severity Catalytic Liquefaction Process'' based on the (CTSL) Catalytic TwoStage Liquefaction of coal.
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.
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 ...

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 ...
WEBThe book's account of the HCoal process, taken as a "baseline case," is a good illustration of the damaging effect of onoff funding. The process was introduced by Hydrocarbon Research, Inc. (HRI) in 1955, as a spinoff of its earlier HOil process. The federal Office of Coal Research underwrote the construction of a demonstration unit in 1965 ...

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 .
