  • The purpose of this report is twofold. First, steady-state models of fixed-bed, dry-bottom gasifiers as reported in the open literature are reviewed for possible incorporation into ASPEN. Second, a suitable model is described. 84 references.
  • Metal halide catalysts, especially zinc chloride, have been demonstrated to be effective catalysts for the conversion of coal to liquid products. Coal is believed to consist of aromatic structural units joined together by various linkages. The present work was undertaken to study the effect of zinc chloride and aluminum chloride on a group of two and three ring aromatic and hydroaromatic substances representative of those found in coal. Reactions were carried out in a batch autoclave using cyclohexane solvent, temperature of 325/sup 0/C and hydrogen or nitrogen pressure of 1600 psig. Dilute solutions of substrates in cyclohexane and a catalystmore » to substrate ratio of 0.54 were used. Substantial substrate reactivity differences were observed for reactions in the presence of ZnCl/sub 2/. These reactions are described. All substrates were quite reactive in the presence of AlCl/sub 3/. This resulted in substantial tar formation as well as high conversions to liquid products. The source of hydrogen used in hydrogenation and cracking of substrates was found to depend on the nature of the catalyst. In the presence of ZnCl/sub 2/, gaseous hydrogen was the major source of hydrogen. In the presence of AlCl/sub 3/, Scholl condensation of substrates or reaction intermediates provided most of the hydrogen. Reaction networks were proposed for hydrogenation and cracking of substrates based on products of reactions of substrates as well as reactions of products of partial hydrogenation of substrates. These networks were explained in terms of carbonium ion mechanisms.« less
  • The research described in this report is intended to explain some of the aspects of molten carbonate fuel cell system. The research currently being investigated is an important part of MCFC performance development.
  • The objectives of this Report are two-fold: (1) to provide overviews of the state-of-the-art and state-of-the-practice with respect to air sparging technology, air sparging models and related or augmentation technologies (e.g., soil vapor extraction); and (2) to provide the basis for the development of the conceptual Decision Tool. The Project Team conducted an exhaustive review of available literature. The complete listing of the documents, numbering several hundred and reviewed as a part of this task, is included in Appendix A. Even with the large amount of material written regarding the development and application of air sparging, there still are significantmore » gaps in the technical community`s understanding of the remediation technology. The results of the literature review are provided in Section 2. In Section 3, an overview of seventeen conceptual, theoretical, mathematical and empirical models is presented. Detailed descriptions of each of the models reviewed is provided in Appendix B. Included in Appendix D is a copy of the questionnaire used to compile information about the models. The remaining sections of the document reflect the analysis and synthesis of the information gleaned during the literature and model reviews. The results of these efforts provide the basis for development of the decision tree and conceptual decision tool for determining applicability and optimization of air sparging. The preliminary decision tree and accompanying information provided in Section 6 describe a three-tiered approach for determining air sparging applicability: comparison with established scenarios; calculation of conceptual design parameters; and the conducting of pilot-scale studies to confirm applicability. The final two sections of this document provide listings of the key success factors which will be used for evaluating the utility of the Decision Tool and descriptions of potential applications for Decision Tool use.« less
