Book Description
The recent demands on the available energy have stimulated the search for alternatives to oil. Methanol, because of its abundance and the availability of technology to produce it from coal, is projected as an alternative source for producing low molecular weight olefins. Utilizing chabazite ion exchanged with ammonium and rare earth chlorides, methanol is converted to ethylene, propylene and propane with carbon yields of 70 to 90% at reaction temperatures of 633 to 723/sup 0/K and pressures from 1 to 18 atmospheres. X-ray diffraction studies, using Cu-K radiation, show no permanent structural changes after a long use. No permanent deactivation was observed even though the catalyst was overheated once, and have been deactivated and regenerated as many as 21 times. The ammonium exchange coupled with the water at high temperature suggest the formation of an ultrastable zeolite. Ethylene yields increase as the temperature increases from 633/sup 0/K to 723/sup 0/K.

Direct Methane to Methanol
Author: Vladimir Arutyunov
Publisher: Elsevier
ISBN: 0444632514
Category : Technology & Engineering
Languages : en
Pages : 321
Book Description
Direct Methane to Methanol: Foundations and Prospects of the Process offers a state-of-the-art account of one of the most interesting and potentially commercial technologies for direct conversion of natural gas into valuable chemicals. The book thoroughly explains the complex and unusual chemistry of the process, as well as possible applications for direct methane to methanol (DMTM). It covers topics involving thermokinetics, pressure, direct oxidation of heavier alkanes, and more, and provides detailed appendices with experimental data and product yields. This book provides all those who work in the field of gas processing and gas chemistry with the theory and experimental data to develop and apply new processes based on direct oxidation of natural gas. All those who deal with oil and natural gas production and processing will learn about this promising technology for the conversion of gas into more valuable chemicals. - Reviews more than 350 publications on high-pressure, low-temperature oxidation of methane and other gas phase hydrocarbons - Contains rare material available for the first time in English - Explains the reasons of previous failure and outlines the way forward for commercial development of the conversion technology - Presents a deep theoretical knowledge of this complex conversion process
