| Low molecular-weight hydrocarbons like ethane, ethylene, and acetylene constitute a class of effective ignition enhancers for natural gas. The oxidative coupling of methane (OCM) has been investigated as a promising route for producing C2 (ethane, ethylene, acetylene) ignition enhancing additives. Ignition calculations show that the use of C2 products enhances ignition in HCCI type engine. OCM is analyzed using a fixed bed reactor and oxygen permeation studies have been carried out for the given OCM catalyst using ceramic membrane reactor. Mn/Na2WO4/SiO2 was selected as the catalyst for carrying out this catalytic reaction because of its reported high stability under reactive conditions and for long reaction periods. Tests of the activity of this catalyst were carried out. It has been tested and shown that the catalyst is considerably stable over long hours of reactor operation. Oxygen permeation of dense oxide membrane reactor is also reported. |
