Abstract
A process for selectively converting methane to ethylene and hydrogen is provided. Methane is brought into contact with a metal powder catalyst and subjected to a pulse train of microwave radiation for a sufficient period of time to effect conversion thereof. The reaction products are recovered.
Claims5
A process for converting methane to ethylene and hydrogen comprising:
- providing methane in a reaction zone containing a catalyst, said catalyst being capable of absorbing microwave radiation;
- irradiating the methane in the presence of said catalyst with pulsed microwave radiation for a sufficient period of time, to thereby convert methane to ethylene and hydrogen;
- and
- recovering said reaction products.

A process for converting methane to ethylene and hydrogen comprising:
- providing a metal powder catalyst, comprising Ni, Co, Fe, and mixtures thereof, in a reaction zone;
- activating the catalyst by removing surface oxides therefrom;
- introducing methane into the reaction zone;
- irradiating the methane in the presence of the catalyst with pulsed microwave radiation, the duration and number of said pulses being controlled to convert the greatest part of the methane to ethylene and hydrogen;
- and
- recovering said reaction products.
