Download or read book Advanced Coal Liquefaction. Final Quarterly Report, October 1, 1995--December 31, 1995 written by and published by . This book was released on 1995 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this quarter, we successfully prepared a granular catalyst required for decomposing compound number 9 in the catalytic membrane reactor. The surface and porous properties of this catalyst are similar to the properties of the ceramic membrane surface. Thus, the catalytic reaction pattern from the granular catalyst is expected to be similar to that from the membranes surface. Further, this catalyst demonstrates a typical property of acid catalysts. The catalytic membrane reactor activity will be resumed in the next quarter using the catalyst prepared in this quarter. In addition, carbon coating of this catalyst did not reduce its acidic property significantly. More study will performed to determine the role of the carbon coating.

Available in PDF, EPUB and Kindle. Book excerpt: This quarterly report summarizes the comprehensive characterization of the silica-modified membrane system designed for studying the conversion of model compound {number_sign}9, 4-(1-naphthylmethyl)bibenzyl, at 400 °C. The conversion of compound {number_sign}9 through the tubular and porous surface of the membrane was determined. No reaction was observed for compound {number_sign}9 through the tubular surface at 400 °C and 200 psi. About 60-70% of compound {number_sign}9 was converted through the porous surface of the silica-modified Al2O3. Majority of the conversion (approximately 30-45%) was resulted from the breaking of bond ''d and/or e'' to form 4-(1-naphthylmethyl)ethylbenzene (or 4-(1- naphthylmethyl)methylbenzene). Minor reactions products (10-20%) were obtained via breaking of bonds a and b to form bibenzyl and methyl bibenzyl. The silica-modified Al2O3 membrane surface appears more reactive but less specific than the carbon surface (as a catalyst) reported in the literature. The result obtained from this quarter provided the background about the reactivity of the membrane surface without packed catalysts. In the next quarter, we will concentrate on the incorporation of the catalyst to evaluate the selective removal of the reaction products by the membrane.

This book was released on 1995 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of industrial catalysts requires that the diffusivity of the reacting species within the catalyst be accurately known. Nowhere is this more important than in the area of coal liquefaction and upgrading of coal liquids. In this area one is faced with the task of processing a number of heavy oils, containing metals and other contaminants, in a variety of process dependent solvents. It is important, therefore, on the basis of predicting catalyst activity, selectivity, and optimizing reactor performance, that the diffusivities of these oil species be accurately known. It is the purpose of the project described here to provide such a correct concept of coal asphaltenes by careful and detailed investigations of asphaltene transport through porous systems under realistic process temperature and pressure conditions. The experimental studies will be coupled with detailed, in-depth statistical and molecular dynamics models intended to provide a fundamental understanding of the overall transport mechanisms.

This book was released on 1995 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research was focused continually on the general tasks: Task 1, molecular organometallic catalysts for hydrogenation and Task 2, organic base catalysts for arene hydrogenation and the hydrotreating of the coal liquids. With regard to Task 1, the [1,5-HDRhCl]2/buffer catalyst system has been investigated in detail to improve its performance. In the presence of CTAB, the stability of the catalyst was improved greatly. The relationship between the turnover number of the catalyst and the reaction time was obtained. Other aromatic compounds such as toluene, n-butylbenzene, tetralin, o-xylene all can be hydrogenated into the corresponding substituted cyclohexane derivatives in more than 94% yields when catalyzed by [1,5- HDRhCl]2 in the presence of small amount of surfactant molecules. The optimum catalyst system has been applied for the hydrogenation of tetralin in the presence of a coal liquid derived from the coal liquefaction. It was found that about 80-85% of tetralin in the mixture was hydrogenated to decalin under the conditions of these experiments. Task 2 was continually focused on the hydrogenation of coal liquids. Institution of dideuterium for dihydrogen in the hydrotreating of coal liquid at 250 °C and 1000 psig of dideuterium yielded a product that was characterized by 2H NMR. Two groups of deuteron located in the region of 6.5-8.0 ppm and 1.0-3.5 ppm, respectively, were observed. The former group was assigned to the deuterons on carbon atoms on aromatic rings and the latter to the deuterons linked to the aliphatic carbon atoms. In addition, naphthalene was hydrogenated completely to tetralin in the presence of the coal liquid under the same conditions, implying that the reduction of multiaromatic compounds was not adversely influenced by the existence of the coal liquid which contains potential catalysts poisons such as sulfur, nitrogen and oxygen.
