A HIGH-POWER X-BAND PULSED MICROWAVE-INDUCED CATALYTIC DECOMPOSITION OF METHANE WITH INTEGRAL ACOUSTIC MEASUREMENTS

A high-power microsecond pulsed microwave system operating in the X-ba nd region was used for the catalytic conversion of methane. Microwave microsecond pulses at repetition rates of 50 and 80 Hz were used to in itiate chemical reactions. The Microwave-Induced Acoustic technique wa s employed in combination with gas chromatography for on-line detectio n of chemical products. Methane was converted to C-2 and C-3 hydrocarb ons. The selectivity of ethane in hydrocarbon products can be >90 %. T he contribution of hydrogen evolution and carbon deposition has been s hown to be important. A comparison between previous experiments perfor med with millisecond pulse durations is given.
