Book excerpt: The report presents the findings of work performed under DOE Contract No. DE-AC22 -95PC95050, Task 3 - Flow Sheet Development. A novel direct coal liquefaction technology was investigated in a program being conducted by CONSOL Inc. with the University of Kentucky Center for Applied Energy Research and LDP Associates. The process concept explored consists of a first-stage coal dissolution step in which the coal is solubilized by hydride ion donation. In the second stage, the products are catalytically upgraded to refinery feedstocks. Integrated first-stage and solids-separation steps were used to prepare feedstocks for second-stage catalytic upgrading. An engineering and economic evaluation was conducted concurrently with experimental work throughout the program. Parameters were established for a low-cost, low-severity first-stage reaction system. A hydride ion reagent system was used to effect high coal conversions of Black Thunder Mine Wyoming subbituminous coal. An integrated first-stage and filtration step was successfully demonstrated and used to produce product filtrates with extremely low solids contents. High filtration rates previously measured off-line in Task 2 studies were obtained in the integrated system. Resid conversions of first-stage products in the second stage were found to be consistently greater than for conventional two-stage liquefaction resids. In Task 5, elementally balanced material balance data were derived from experimental results and an integrated liquefaction system balance was completed. The economic analysis indicates that the production of refined product (gasoline) via this novel direct liquefaction technology is higher than the cost associated with conventional two-stage liquefaction technologies. However, several approaches to reduce costs for the conceptual commercial plant were recommended. These approaches will be investigated in the next task (Task 4) of the program.

Available in PDF, EPUB and Kindle. Book excerpt: A novel direct coal liquefaction technology is being investigated in a program being conducted by CONSOL Inc. with the University of Kentucky, Center for Applied Energy Research and LDP Associates under DOE Contract DE-AC22-95PC95050. The novel concept consists of a new approach to coal liquefaction chemistry which avoids some of the inherent limitations of current high-temperature thermal liquefaction processes. The chemistry employed is based on hydride ion donation to solubilize coal at temperatures (350-400[degrees]C) significantly lower than those typically used in conventional coal liquefaction. The process concept being explored consists of two reaction stages. In the first stage, the coal is solubilized by hydride ion donation. In the second, the products are catalytically upgraded to acceptable refinery feedstocks. The program explores not only the initial solubilization step, but integration of the subsequent processing steps, including an interstage solids-separation step, to produce distillate products. A unique feature of the process concept is that many of the individual reaction steps can be decoupled, because little recycle around the liquefaction system is expected. This allows for considerable latitude in the process design. Furthermore, this has allowed for each key element in the process to be explored independently in laboratory work conducted under Task 2 of the program.

This book was released on 1995 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: CONSOL Inc., the University of Kentucky/Center for Applied Energy Research (CAER), and LDP Associates are conducting a three-year research program to explore the technical and economic feasibility of a novel direct coal liquefaction concept. The purpose of this research program is to explore a new approach to direct coal liquefaction in which the primary coal dissolution step is effected by chemical rather than thermal cleavage of bonds in the coal. This is done at a temperature which is significantly lower than that typically used in conventional coal liquefaction. Reaction at this low temperature results in high conversion of the coal to a solubilized form, with little hydrocarbon gas make, and avoids the thermally induced retrograde reactions which are unavoidable in conventional thermal processes. In addition, for low-rank coals, a substantial portion of the oxygen in the coal is removed as CO and CO2 during the dissolution. The higher selectivity to liquid products and rejection of oxygen as carbon oxides should result in improved hydrogen utilization. The basis of the novel concept is the discovery made by CONSOL R & D that certain hydride transfer agents are very active for coal dissolution at temperatures in the range of 350°C. Because of the exploratory nature of the research, the project is divided into sequential tasks that are designed to first evaluate key elements of the process is presented for the following tasks: management plan; evaluation of process steps; engineering and economic study and reporting.

This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activities this quarter were conducted under Tasks 2, 3, and 5. Task 2 work concentrated on evaluating the effects of low-severity, first-stage reaction conditions on coal conversions of lignite, subbituminous, and bituminous coals. The impact of artificially weathering bituminous coal was investigated. Large quantities of first-stage product were made using the one-liter reactor for subsequent filtration and catalytic upgrading tests. Test conditions and coal conversions for all microautoclave and one-liter tests made this quarter are presented. Filtration tests examined lignite, subbituminous, and bituminous coal products. The effects on resid conversion of second-stage reaction conditions and catalyst recycle were studied. Task 3 work included the successful transfer of first-stage reactor products to a receiver and the design of an interstage filter. Task 5 work included an ongoing review of the technical and patent literature and expansion of the annotated bibliography. Mass and elemental balances were obtained for selected tests.

Task 2 work continued to evaluate the effects of low-severity, first-stage reaction conditions on coal conversions of lignite and subbituminous coal. Solvent type, solvent-to-dry-coal ratio, and substitution of CO and CO/methanol for hydride ion reagents were investigated in microautoclave tests. Large quantities of first-stage product were made using the one-liter reactor for subsequent filtration and catalytic upgrading tests. Filtration was performed on three one- liter autoclave products; each one requiring different filtration conditions. A second-stage catalytic upgrading parametric study was completed. In Task 3, designs were completed for both the large-scale filtration apparatus and the large-scale second-stage catalytic reactor system.
