Numerical Study to Define Initial Thermal Integration Window for Methane Oxidative Coupling with Dehydroaromatization Reactors

Miniplant-Scale Analysis of Oxidative Coupling of Methane Process

For more than three decades, Oxidative Coupling of Methane (OCM) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. Developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...

Oxidative Coupling of Methane to Ethylene Over Sodium Promoted Manganese Oxide

Manganese oxide catalyst promoted with sodium and supported on silica exhibits fairly good activity and selectivity towards the synthesis of ethylene from methane at the optimum operating conditions. Methane and oxygen were fed into a tubular fixed bed reactor packed with catalyst under atmospheric pressure. The effects of temperature, residence time and feed composition on conversion, selectiv...

Potassium/calcium/nickel oxide catalysts for oxidative coupling of methane

A series of potassium/calcium/nickel oxides were tested for the oxidative coupling of methane (OCM) at 843-943 K and water addition to the feed at O-65 mol-%. The K/Ni ratios varied from 0.0-0.6 and Ca/Ni from 0.0-11; catalysts with no nickel were also tested. At least 10% water in the feed and temperatures lower than ca. 940 K were necessary to keep nickel-containing catalysts from converting ...
