Book excerpt: Reported herein are the details and results of Laboratory-Scale experiments using sub-bituminous and bituminous coal concluded at Hydrocarbon Research, Inc., under DOE Contract No. AC22-88PCB8818 during the period October 1, 1988 to June 30, 1993. The work described in this report is primarily concerned with tests on a Laboratory Scale primarily using microautoclaves. Experiments were conducted evaluating coal, solvents, start-up oils, catalysts, thermal treatments, C0[sub 2] addition and sulfur compound effects. Other microautoclave tests are included in the companion topical reports for this contract, DE-88818-TOP-01 & 02 on Sub-Bituminous and Bituminous Bench-Scale and PDU activities.

Book excerpt: This is the final report of a four year and ten month contract starting on October 1, 1988 to July 31, 1993 with the US Department of Energy to study and improve Close-Coupled Catalytic Two-Stage Direct Liquefaction of coal by producing high yields of distillate with improved quality at lower capital and production costs in comparison to existing technologies. Laboratory, Bench and PDU scale studies on sub-bituminous and bituminous coals are summarized and referenced in this volume. Details are presented in the three topical reports of this contract; CTSL Process Bench Studies and PDU Scale-Up with Sub-Bituminous Coal-DE-88818-TOP-1, CTSL Process Bench Studies with Bituminous Coal-DE-88818-TOP-2, and CTSL Process Laboratory Scale Studies, Modelling and Technical Assessment-DE-88818-TOP-3. Results are summarized on experiments and studies covering several process configurations, cleaned coals, solid separation methods, additives and catalysts both dispersed and supported. Laboratory microautoclave scale experiments, economic analysis and modelling studies are also included along with the PDU-Scale-Up of the CTSL processing of sub-bituminous Black Thunder Mine Wyoming coal. During this DOE/HRI effort, high distillate yields were maintained at higher throughput rates while quality was markedly improved using on-line hydrotreating and cleaned coals. Solid separations options of filtration and delayed coking were evaluated on a Bench-Scale with filtration successfully scaled to a PDU demonstration. Directions for future direct coal liquefaction related work are outlined herein based on the results from this and previous programs.

This book was released on 1993 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reported are the details and results of Laboratory and Bench-Scale experiments using sub-bituminous coal conducted at Hydrocarbon Research, Inc., under DOE Contract No. DE-AC22-88PC88818 during the period October 1, 1988 to December 31, 1992. The work described is primarily concerned with testing of the baseline Catalytic Two-Stage Liquefaction (CTSL{trademark}) process with comparisons with other two stage process configurations, catalyst evaluations and unit operations such as solid separation, pretreatments, on-line hydrotreating, and an examination of new concepts. In the overall program, three coals were evaluated, bituminous Illinois No. 6, Burning Star and sub-bituminous Wyoming Black Thunder and New Mexico McKinley Mine seams. The results from a total of 16 bench-scale runs are reported and analyzed in detail. The runs (experiments) concern process variables, variable reactor volumes, catalysts (both supported, dispersed and rejuvenated), coal cleaned by agglomeration, hot slurry treatments, reactor sequence, on-line hydrotreating, dispersed catalyst with pretreatment reactors and CO2/coal effects. The tests involving the Wyoming and New Mexico Coals are reported herein, and the tests involving the Illinois coal are described in Topical Report No. 2. On a laboratory scale, microautoclave tests evaluating coal, start-up oils, catalysts, thermal treatment, CO2 addition and sulfur compound effects were conducted and reported in Topical Report No. 3. Other microautoclave tests are described in the Bench Run sections to which they refer such as: rejuvenated catalyst, coker liquids and cleaned coals. The microautoclave tests conducted for modelling the CTSL{trademark} process are described in the CTSL{trademark} Modelling section of Topical Report No. 3 under this contract.

This book was released on 1992 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in this project centered upon developing and evaluating catalysts and process improvements for coal liquefaction in the two-stage, close-coupled catalytic process. The major results are summarized here and they are described in more detail under each Task. In tasks for coal pretreatment and beneficiation, it was shown for coal handling that drying of both lignite or subbituminous coals using warm air, vacuum oven or exposing to air for long time was detrimental to subsequent liquefaction. Both laboratory and bench-scale beneficiations indicated that in order to achieve increased liquefaction yield for Illinois No. 6 bituminous coal, size separation with in sink-float technique should be used. For subbituminous coal, the best beneficiation was aqueous SO2 treatment, which reduced mineral matter. In the case of lignite, the fines should be rejected prior to aqueous SO2 treatment and sink-float gravity separation. In liquefying coals with supported catalysts in both first and second stages, coal conversion was highest (93%) with Illinois No. 6 coal, which also had the highest total liquid yield of 80%, however, the product contained unacceptably high level of resid (30%). Both low rank coals gave lower conversion (85--87%) and liquid yields (57--59%), but lighter products (no resid). The analysis of spent first stage catalysts indicated significant sodium and calcium deposits causing severe deactivation. The second stage catalysts were in better condition showing high surface areas and low coke and metal deposits. The use of dispersed catalyst in the first stage would combat the severe deactivation.

Book excerpt: Research continued on two-stage close coupled catalytic coal liquefaction. During the second quarter of 1990, experimental studies were carried out in the microautoclave and Bench Units. Updating of the economics of two-stage processing continued as did process modelling activities. Bench-scale operations consisted of the completion of Run 227-66 (CC-8), an OTISCA cleaned coal evaluation, and Run CC-9, a solids separation study of delayed coking. The OTISCA Cleaned Coal Evaluation and Delayed Coking Trials were successfully concluded. The economics of Eastern US bituminous coal liquefaction were updated to a 1991 basis. For an 8400 ton/day plant, an investment of 1.6 billion is estimated. 1 fig., 13 tabs.

Book excerpt: Research under way in this project centers upon developing and evaluation catalysts and process improvements for coal liquefaction in the two-stage close-coupled catalytic process. The project is being carried out under contract to the United States Department of Energy. As discussed in the previous quarterly report, the results showed that C/T liquefaction is not a good option for Black Thunder subbituminous coal. In this quarter, the liquefaction of Black Thunder coal was continued. The studies showed that the combination of Wender's sulfated iron oxide with molybdenum is the most effective catalyst for this liquefaction. Compared with other iron/molybdenum catalysts, distillate yields were increased and the catalyst deactivation was not as severe as for the supported (extruded) catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: The first calendar quarter of 1991 was a productive period with two bench-scale studies, microautoclave support studies, mini-Process Development Unit (PDU) preparations, and process modelling. Several catalyst presulfiding agents and CO2 effects upon liquefaction were evaluated in microautoclave scale tests. Dimethyl disulfide will be used for the PDU scale-up based on the results of these tests and prior data. Carbon dioxide appears to enhance coal conversion; however, gas and water yields are increased indicating possible water gas shift-hydrocarbon synthesis reactions. In the bench-scale studies, the rejuvenation of spent catalyst with acid and carbon burn-off produced catalytic activity akin to fresh and catalyst in a 12 day evaluation. A 14 day study of the addition of high concentrations of CO2 to a sub-bituminous coal liquefaction system demonstrated the occurrence of water gas shift hydrocarbon synthesis reactions and conversely higher coal conversions and distillate yields with high hydrogen consumptions. Preparations for a PDU Demonstration Run on Black Thunder Mine coal are underway. The British Coal Filtration Process will be used for solid separation. The results of microautoclave scale tests on Illinois, Ohio and Black Thunder Mine coals were reviewed and statistically analyzed to provide a sound basis for kinetic interpretation.
