a moving bed reactor system is provided . the system comprises at least one gas inlet , a distributor , a temperature control , a plurality of electrodes , and a spark control circuit . the spark control circuit drives the electrodes and generates a multi - arc discharge when the system is loaded with particles and a gas at approximately atmospheric pressure or greater is being pumped through the system . the multi - arc discharge is useful to create activated species which may improve the rate of a chemical reaction taking place in the moving bed reactor system .
