Methane, the major constituent of natural gas, had been converted to higher hydrocarbons by a microwave plasma. The yield of C2+ product could be increased from 29.2% to 42.2% with increasing plasma power(40~120 watt) and decreasing flow rate(40~5 mL/min) of methane. With catalyst, the selectivities...

Methane, the major constituent of natural gas, had been converted to higher hydrocarbons by a microwave plasma. The yield of C2+ product could be increased from 29.2% to 42.2% with increasing plasma power(40~120 watt) and decreasing flow rate(40~5 mL/min) of methane. With catalyst, the selectivities of ethylene and increased while yield of C2+ remaining constant. Among various catalysts, Fe catalyst showed the highest ethylene selectivity of 30%. A natural gas could produce more C2+ than a pure methane. This is due to high reactivity of ethane and propane in the natural gas.
