Book A Study of Methylcyclohexane Dehydrogenation Over a Platinum on alumina Catalyst at 602f

Download or read book A Study of Methylcyclohexane Dehydrogenation Over a Platinum on alumina Catalyst at 602f written by Alan E. Zengel and published by . This book was released on 1967 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A laboratory reactor was set up and operated as a differential catalytic reactor for a study of the dehydrogenation of methylcyclohexane over an 0.8 weight percent platinum on alumina catalyst. The reactor was operated as a differential reactor; i.e., with only small conversions, in order to reduce the effect of the large endothermic heat of reaction associated with the dehydrogenation of methylcyclohexane. The main tasks were to set up and successfully operate a reactor that could be used in laboratory kinetics studies. It was also necessary to determine the conditions for a study of the chemical reaction rate of methylcyclohexane dehydrogenation that was unencumbered by physical rate-limiting processes. Reactions were run at 76 psia and 602F. The effect of diffusion within the catalyst particle was minimized by using particles that were crushed and screened through a 50 mesh Tyler screen and retained on a 70 mesh Tyler screen. The surface reaction was found to be first order with respect to methylcyclohexane partial pressure under the conditions studied. Although the data are too limited to determine the rate limiting step, a discussion of the rate data along with results reported in the literature for similar rate studies suggests that the conversion of methylcyclohexane to toluene and hydrogen is limited by a single site-surface reaction.

Download or read book A Kinetic Study of the Catalytic Dehydrogenation of Methylcyclohexane at 600 650 and 700F and a Pressure of 5 Atmospheres written by Herbert R Lander (Jr) and published by . This book was released on 1970 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel enthalpy offers a readily available heat sink and can be used to dissipate the aerodynamic heating that results from sustained high speed flight in the earth's atmosphere, but is effective only up to certain levels of temperature. Catalytically enhanced heat-absorbing chemical reactions, however, can be used to increase the heat sink capacity from the fuel enthalpy. These reactions include dehydrogenation, dehydrocyclization, depolymerization, and hydrocarcking. The dehydrogenation of methylcyclohexane over a commercially available platinum-alumina catalyst bed will approximately double the heat sink from fuel enthalpy. The dehydrogenation reaction was studied at temperatures of 600, 650, and 700 degrees F and a pressure of 5 atmospheres. Tabulations and plots of test data are presented on the effects of time, reaction rate, molar feed ratio, presence of toluene, presence of reactor inerts, reaction pressure, and temperature.

Book Dehydrogenation of Cycloalkanes Catalyzed by Metals in Supported Molten Salts

Download or read book Dehydrogenation of Cycloalkanes Catalyzed by Metals in Supported Molten Salts written by Darrell P. Eyman and published by . This book was released on 1988 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies were designed to evaluate the potential advantages associated with the use of transition metal microcrystallites dispersed in molten salts in the dehydrogenation of cyclic hydrocarbons which are viewed as potential endothermic fuel candidates. Although both molten salt pools and Supported Molten Salt Catalysts (SMSC) were studied, only SMSC gave results which show any developmental promise for use in the endothermic fuels initiative presently underway at AFWAL. All of the SMSC studies were performed in packed tube reactors and were designed to permit comparison with data for conventional heterogeneous catalysts used under the same operational conditions. The majority of the studies involved the dehydrogenation of methylcyclohexane (MCH) to toluene. This reaction system was selected because of the existing data base generated by the extensive studies at Shell Development using conventional heterogeneous platinum catalysts usually on alumina supports. Two modifications were made to the original statement of work. The first involved a one man-month study of platinum, in both conventional and SMSC mode, as an heterogeneous catalyst for the coupled dehydrogenation - Retro-diels-Alder reaction of JP-10 (exo-octahydro-4,7-methano-1H-indene). The second involved as its primary endeavor the use of alkali metal hydroxide eutectics in SMSC for catalytic dehydrogenation of methylcyclohexane to toluene. (aw).
