چکیده:

Hard metal compounds producing such as metallic carbides has a great industrial importance. reaction of metal oxides with carbon source materials uses for metalic carbides producing. Commonly, in metal processing factories, coal is used as the reducing agent in solid state reduction of metal oxides for metalic carbides producing. These reactions temperature similar to high temperature reactions is between 900 to 1200 C. Use of methane instead of coke as a reducing agent has some advantages: one of the most important advantage among them is reactiontemperature decreasing which has a great importance. With attention to higher reactivity ofmethane rather than solid carbon and higher kinetic rate in gas-solid reaction in comparison withthe solid-solid reaction, methane has higher reducing capability than carbon which creates a potentrial to decrease reduction operating temperature. So because of importance of methane application, in the present work, a brief review of literature survey in the field of metal or hard metalic carbides producing by noncatalytic methane reaction with metal oxides was studied.
