This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective for this research is to optimize the design and operation of the bench scale batch reactor (SCTBR) for coal liquefaction at short contact times (0.01 to 10 minutes or longer). This reactor is simple enough and low enough in cost to serve as a suitable replacement for the traditional tubing-bomb reactors for many coal liquefaction and other high-pressure, high-temperature reaction studies. The liquefaction of selected Argonne Premium coals and the role of organic oxygen components of the coal and their reaction pathways at very low conversions are being investigated.

Book excerpt: The objective of this research is to optimize the design and operation of the bench scale batch reactor (SCTBR) f or coal liquefaction at short contact times (0.01 to 10 minutes or longer). Additional objectives are to study the kinetics of direct coal liquefaction particularly at short reaction times, and to investigate the role of the organic oxygen components of coal and their reaction pathways during liquefaction. Many of those objectives have already been achieved and others are still in progress. This quarterly report covers further progress toward those objectives.

This book was released on 1994 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective for this research is to optimize the design and operation of the bench scale batch reactor (STBR) for coat liquefaction at short contact times (0.01 to 10 minutes). This reactor is simple and low enough in cost to serve as a suitable replacement for the traditional tubing-bomb reactors for coal liquefaction and other high-pressure, high-temperature reaction studies. The details of the reactor system are shown in Figure 2. The heating bath used is a Techne IFB-52 industrial fluidized sand bath, which maintains a reaction temperature of "2°C. The 30 cm3 reactor is capable of containing up to 17 MPa (2500 psi) pressure at temperatures up to 550°C. The tubing used for preheater and precooler was 1/4in. 316 stainless steel with wall thickness of 0.035in. The lengths of the preheater and precooler are selected based on the particular process being studied. Since a gas (e.g. hydrogen or nitrogen) is bubbled through the reaction mixture under pressure and out through a letdown valve, a small water cooled condenser above the reactor before the let-down valve is added to avoid loss of solvent or other low boiling components. Coal liquefaction runs are made by preparing slurries of coal in reagent grade tetralin. Various ratios of tetralin to coal are used, and in some cases, a catalyst such as Ni/Mo on alumina is added.

Additional objectives are to study the kinetics of direct coal liquefaction particularly at short reaction times and to investigate the role of organic oxygen components of coal and their reaction pathways during coal liquefaction. Many of those objectives have already been achieved. This quarterly report discusses further kinetic studies of the liquefaction of Illinois #6 bituminous coal, Wyodak-Anderson subbituminous coal, and Pittsburgh #8 bituminous coal. The thermodynamic characteristics of the extraction stage at the start of the liquefaction process in the liquefaction of Illinois #6 coal is also discussed. Further work has also been done to attempt to clarify the role of the liquefaction solvent in the direct liquefaction process.

Many of those objectives have already been achieved and others are still in progress. This quarterly report covers further progress toward those objectives. Much of the previous quarterly report was concerned mainly in the retrograde reactions occurring during the liquefaction process. This report is largely devoted to the kinetics and mechanisms of the liquefaction process itself and the influence of the liquefaction solvents.

Available in PDF, EPUB and Kindle. Book excerpt: A detailed evaluation of the bench unit data on Black Thunder feedstocks was completed. The results show that in a once-through operation using counterflow, reactor technology coal conversions in excess of 90% could be obtained, giving distillable oil yields in the range 60--65 wt % on MAF coal. The remaining non-distillable oil fraction which represents 20--25 wt % on MAF coal is a source of additional distillable oil in further processing, for example, bottoms recycle operation. C1-C3 gas yields were generally in the order of 6--8 wt %. In autoclave studies, Illinois No. 6 coal was found to be much less reactive than Black Thunder coal, and did not respond well to solubilization with carbon monoxide/steam. Process severity was, therefore, increased for bench unit operations on Illinois No. 6 coal, and work has concentrated on the use of hydrogen rather than carbon monoxide for solubilization. Preliminary coking studies on the resid from bench unit runs on Black Thunder coal were also carried out. Distillable liquid yields of 55--60 wt % were obtained. The technical and economic study to be carried out by Kilborn Engineering Company has been initiated.
