Conversion of Methane by Oxidative Coupling

Thank you for downloading analysis synthesis and design of chemical processes. Maybe you have knowledge that, people have search numerous times for their chosen readings like this analysis synthesis and design of chemical processes, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some harmful virus inside their desktop computer.

Analysis Synthesis And Design Of Chemical Processes

Natural gas is an abundant resource in various parts of the world. Methane is the major component of natural gas, often comprising over 90 mol% of the hydrocarbon fraction of the gas. Methane itself is primarily used as a fuel, while the nonmethane components can be separated and used as feedstocks for the production of chemicals or liquid fuels. In many cases, however, natural gas reserves are found in locations distant from their place of utilization. Since it is not generally economical to transport liquefied natural gas, efficient methods are needed to convert methane into transportable liquid products. A possible route is oxidative dimerization of methane followed by oligomer-ization of the C2 products.

Action of chromium oxide as a catalyst in the course of KMnO4 decomposition

Different ratios of vanadium pentoxide supported on aluminum phosphate (1-30 mol%) have been prepared by an impregnation method. The original and calcined samples were characterized by TG, DTG, DSC, X-ray diffraction, IR spectra, N 2 adsorption and electrical conductivity measurements. The catalytic decomposition of ethanol has been carried out at 210°C in a flow system at 1 atm using air as a carrier gas. The results indicate that the catalysts calcined at 400°C were active and selective towards ethene formation whereas the samples calcined at 600°C showed a drastic reduction in both activity and selectivity.

Development and utilization of lime‐mud waste as filler for production of green paper

In this work, the production of dimethyl ether (DME) from methanol over natural kaolin clay modified through impregnation with various percentages of H2SO4, WO3, or ZrO2 catalysts was investigated. The prepared catalysts were characterized via X-ray fluorescence, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and N2-sorption analysis. The acidity of these catalysts was determined through the dehydration of isopropyl alcohol and the chemisorption of pyridine. The catalytic activity performance revealed that the addition of modifiers into kaolin enhanced the latter's activity toward DME production. In addition, the kaolin clay modified with 10 wt% ZrO2 exhibited excellent activity of 98% conversion with 100% selectivity at 275 °C. Moreover, this catalyst could proceed the reaction for a long time (6 days) without any noticeable deactivation. The remarkable improvement in the catalytic performance achievement was well correlated with the acidity and the structure of the catalysts.
