Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
94 words
A METHOD FOR CONDUCTING A CHEMICAL REACTION IN AN ELECTRIC DISCHARGE WHICH COMPRISES PASSING A GASIFORM REACTANT UPWARDLY THROUGH AN ELONGATED REACTION ZONE OF RESTRICTED CROSS-SECTIONAL AREA, MAINTAING A DENSE PHASE FLUIDIZED BED OF ELECTRICALLY CONDUCTIVE SOLID PARTICLES IN SAID REACTION ZONE, APPLYING AN ELECTRICAL POTENTIAL BETWEEN A PLURALITY OF FIXED POINTS AN ELECTRICAL PATH OF FLOW SAID REACTANT, SAID FLUIDIZED BED BEING MAINTAINED BETWEEN SAID FIXED POINTS, SAID ELECTRICAL POTENTIAL HAVING A MAGMITUDE SUFFICIENT TO PRODUCE FLOW OF ELECTEIC CURRENT BETWEEN SAID POINTS CAUSING ELECTRIC SPARK DISCHARGES BETWEEN THE SOLID PARTICLES BETWEEN SAID
