This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. 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.

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.

Book excerpt: The objective of this research is to optimize the design and operation of the bench scale batch reactor (SCTBR) for studying direct coal liquefaction at short contact times (.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 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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the use of a novel laboratory-scale batch reactor, designed by the University of Delaware, to study the kinetics of coal liquefaction resid reactivity. The short time batch reactor (STBR) is capable of conducting reactions at temperatures up to 450°C and pressures up to 2500 psi at well-defined reaction times from a few seconds to 30 min or longer. Sixty experiments were conducted with the STBR in this project. The products of the resid/tetralin/hydrogen reaction were separated by solubility, and several analytical procedures were used to evaluate the reaction products, including thermogravimetric analysis (TGA), gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Changes were monitored in the boiling ranges of the products, as a function of process conditions (time, temperature, and tetralin donor solvent-to-resid ratio), with and without catalysts. Two distillation resid samples were studied; Sample 1 is the resid of the second stage product stream from Wilsonville Run 259 which used Pittsburgh seam coal (Ireland mine) bituminous coal, and Sample 2 is the resid of the same streak from Wilsonville Run 260 which used Wyodak and Anderson (Black Thunder Mine) subbituminous coal. It was determined that the resid reactivity was different for the two samples studied. The results demonstrate that further development of this experimental method is warranted to empirically assess resid reactivity and to provide data for use in the construction of an empirical model of coal conversion in the direct liquefaction process.
