Botts, T E; Powell, J R

A process is described for electrochemically gasifying coal, comprising the steps of: (a) establishing a flowing stream including a slurry of coal particulate and a liquid, electrode members distributed in the slurry, and an electrolyte in electrically conducting relationship with the members and the slurry, (b) establishing a magnetic field of predetermined strength transversely through a portion of the stream. The field is effective to electrically polarize the electrode members as they flow through the field, thereby causing the members to operate with the electrolyte to electrochemically gasify the coal particulate and generate H/sub 2/ and CO/sub 2/ gases at opposite ends, respectively, of the members, (c) providing gas collecting means operatively positioned to collect the gases as they rise from the slurry, and operating the gas collecting means to collect the gases.
