Abstract

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expectedmore »« less

Coprocessing - The hydrogenation of lignite together with residual oils

Conference Lenz, U; Wawrzinek, J; Giehr, A - Am. Chem. Soc., Div. Gas Fuel Chem., Prepr.; (United States)

The current overflow on the crude oil market must not obscure the fact that world oil resources are limited. Instead, it must be our goal to develop practicable concepts for the conversion of fossil raw materials and optimize their economic viability. The joint development programme of the Rheinische Braunkohlenwerke Kraftstoff AG and the Union Rheinische Braukohlen Kraftstoff AG for the catalytic hydrogenation of fossil raw materials in the liquid phase aims at this goal.

Integration of waste pyrolysis with coal/oil coprocessing

Conference Hu, J; Zhou, P; Lee, T; ...

HTI has developed a novel process, HTI CoPro Plus{trademark}, to produce alternative fuels and chemicals from the combined liquefaction of waste materials, coal, and heavy petroleum residues. Promising results have been obtained from a series of bench tests (PB-01 through PB-06) under the DOE Proof of Concept Program. Recently, HTI acquired a proven technology for the mild co-pyrolysis of used rubber tires and waste refinery or lube oils, developed by the University of Wyoming and Amoco. The feasibility of integration of pyrolysis with coal-oil coprocessing was studied in the eighth bench run (PB-08) of the program. The objective of Runmore »« less
Coal-oil coprocessing at HTI - development and improvement of the technology

Conference Stalzer, R; Lee, L; Hu, J; ...

Co-Processing refers to the combined processing of coal and petroleum-derived heavy oil feedstocks. The coal feedstocks used are those typically utilized in direct coal liquefaction: bituminous, subbituminous, and lignites. Petroleum-derived oil, is typically a petroleum residuum, containing at least 70 W% material boiling above 525{degrees}C. The combined coal and oil feedstocks are processed simultaneously with the dual objective of liquefying the coal and upgrading the petroleum-derived residuum to lower boiling (<525{degrees}C) premium products. HTI`s investigation of the Co-Processing technology has included work performed in laboratory, bench and PDU scale operations. The concept of co-processing technology is quite simple and amore »« less

Coal coprocessing with used oil

Conference Mulgaonkar, M; Kuo, C; Tarrer, A

Waste oil coprocessing with coal appears to be an alternative to both conventional oil disposal and coal liquefaction using hydrogen donor solvents. Coprocessing experiments carried out in tubing bombs yielded coal conversions of up to 90% at temperatures from 400--450 C, at cold H{sub 2} pressures of 800--1,250 psig, and at reaction times of 15--60 minutes with and without iron-based catalyst. The effect of different coal loadings on conversion and selectivity was also investigated. The highest conversions were obtained for a coal loading on oil of about 20% w/w. The effect of ionic and non-ionic surfactants on coal liquefaction weremore »« less
