Download or read book Natural Gas Conversion V written by A. Parmaliana and published by Elsevier. This book was released on 1998-09-17 with total page 1005 pages. Available in PDF, EPUB and Kindle. Book excerpt: On January 1988, the ascertained and economically accessible reserves of Natural Gas (NG) amounted to over 144,000 billion cubic meters worldwide, corresponding to 124 billion tons of oil equivalents (comparable with the liquid oil reserves, which are estimated to be 138 billion TOE). It is hypothesized that the volume of NG reserve will continue to grow at the same rate of the last decade. Forecasts on production indicate a potential increase from about 2,000 billion cubic meters in 1990 to not more than 3,300 billion cubic meters in 2010, even in a high economic development scenario. NG consumption represents only one half of oil: 1.9 billion TOE/y as compared to 3.5 of oil. Consequently, in the future gas will exceed oil as a carbon atom source. In the future the potential for getting energetic vectors or petrochemicals from NG will continue to grow. The topics covered in Natural Gas Conversion V reflect the large global R&D effort to look for new and economic ways of NG exploitation. These range from the direct conversion of methane and light paraffins to the indirect conversion through synthesis gas to fuels and chemicals. Particularly underlined and visible are the technologies already commercially viable. These proceedings prove that mature and technologically feasible processes for natural gas conversion are already available and that new and improved catalytic approaches are currently developing, the validity and feasibility of which will soon be documented. This is an exciting area of modern catalysis, which will certainly open novel and rewarding perspectives for the chemical, energy and petrochemical industries.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in catalyst development for reactions such as Fischer-Tropsch synthesis (FTS) has been impeded by the time consuming characterisation and catalytic testing of new formulations. Hence, this thesis discusses the development of high-throughput (HT) techniques for studying the deactivation of cobalt based catalysts under simulated FTS conditions. Libraries were rapidly synthesised by incipient wetness methods utilising robotic platforms and then treated in arrays under conditions designed to cause rapid ageing. HT X-ray diffraction (XRD) was performed before and after the ageing test to monitor the deactivation of the catalysts by sintering of the active metal particles or loss of metallic cobalt. HT thermogravimetric analysis in 5 % H2 was utilised to probe the reducibility of the catalysts and this information was then combined with results from XRD to inform decisions on which formulations to scale-up for further testing. This approach led to the discovery of highly stable Co/Ru/Mg/[gamma]-Al2O3 catalysts. Thorough characterisation of selected hits was carried out to understand the phase assemblage. In addition to the high stability of Co/Ru/Mg/[gamma]-Al2O3 catalysts, there was also a lowering of intrinsic activity. The degree to which the intrinsic activity was decreased was dependent on the amount of Mg in the catalyst and more specifically, the amount of Mg in close proximity to Co as identified by the amount of Mg incorporated into MgxCo3-xO4 phases prior to activation. In addition to incipient wetness synthesis, a method was also developed to perform HT co-precipitation synthesis with the aid of robotic platforms. HT synthesis was coupled with HT XRD to determine synthesis conditions giving rise to high surface area, phase-pure magnesium aluminate supports.

This book was released on 1994 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial experiments have been performed to determine the best activation procedure for the high cobalt, high activity, Y zeolite-supported F-T catalyst. At this time the temperature used for the lower cobalt-level catalyst appears to be the best. Future activation experiments should be done at lower temperatures, but for longer periods of time. The runs outlined in this report and several in earlier reports were done with the standard reactor loading of 13 g but with high activity catalysts. In all of these runs a significant temperature exotherm was observed on the catalyst bed. In future runs less catalyst will be used with the same or more quartz sand diluent. This should reduce or eliminate the catalyst bed exotherm and make it easier to evaluate two different catalysts at the same temperature.

This book was released on 1992 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four new catalysts were prepared and screened during this reporting period. They were compared to a reference Co-based catalyst (TC 211) which was developed under a previous DOE contract No. AC22-84PC10028. The reference catalyst was prepared on a special steamed and acid-washed Y zeolite support. The four new catalysts were prepared on a commercial product which is a specially-prepared Y zeolite. A special solvent was used to impregnate contract to a division of Union Carbide which is now part of UOP. Catalyst TC 211 was prepared by impregnating metals onto a laboratory steamed and acid-washed Y zeolite. A special impregnation solvent was used. At similar operating conditions, the four catalysts tested were less active and more selective to methane than the reference catalyst. A temperature change was made in the testing of these four catalysts (condition 1 to condition 2) to obtain conversions comparable to that obtained with the reference catalyst. Higher methane selectivity was noted for these catalysts when comparisons were made at similar conversion levels. When the new catalysts were evaluated at different conversions resulting from changes in feed rate at the same temperature (condition 2 to condition 3) high methane selectivity persisted. Thus these catalysts did not exhibit the expected lower methane selectivity at higher conversion. The four catalysts tested were intrinsically more selective to methane than the reference catalyst. They were, however, similar to the reference catalyst in their low selectivity to alcohols (Table 5). Of the four catalysts, catalyst 6531-161 which contained ruthenium appeared to be the most selective for methane.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this contract is to examine the relationship between catalytic properties and the function of cobalt Fischer-Tropsch catalysts and to apply this fundamental knowledge to the development of a stable cobalt-based catalyst with a low methane-plus-ethane selectivity for use in slurry reactors. An experimental cobalt catalyst 585R2723 was tested three times in the fixed-bed reactor. The objective of the tests was to identify suitable testing conditions for screening catalyst. The?-alumina was determined to be a suitable diluent medium for controlling the catalyst bed temperature close to the inlet temperature. With 13 g of catalyst and 155 g of diluent, the catalyst maximum temperature were within 2°C from the inlet temperatures. As a result of this work, 210°C and 21 atm were shown to result in low methane selectivity and were used as initial conditions in the catalyst screening test. Ethane, which along with methane is undesirable, is typically produced with low selectivity and follows the same trend as methane. Other work reported here indicated that methane selectivity increases with increasing temperature but is not excessively high at 230°C. Consequently, the catalyst screening test should include an evaluation of the catalyst performance at 230°C. During Run 67, the increase in temperature from 210°C to 230°C was initiated at 30 hours on-stream.
