NOVELTY - An apparatus has reactor vessel having inlet and an outlet, plasma reactor having divergent electrode and divergent nozzle which is in fluid communication with interior of reactor vessel, power supply in electrical communication with divergent electrode and divergent nozzle configured to apply voltage potential across divergent electrode and divergent nozzle, and plasma reactor working gas source configured to supply working gas to plasma reactor in which power supply is configured to apply voltage potential across divergent electrode and divergent nozzle to partially dissociate working gas.    USE - An apparatus for plasma partial dissociation of gases and carbonaceous materials (claimed).    ADVANTAGE - The apparatus saves energy costs. Plasma reactors using graphite electrodes and/or nozzles provide acceptable yields of oxygen and carbon monoxide while using inexpensive materials for electrode and/or nozzle.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) plasma partial dissociation of gases which involves providing an apparatus, introducing working gas from working gas source into plasma reactor, adjusting power supply to apply voltage potential across divergent electrode and divergent nozzle which causes working gas to partially dissociate and generate plasma containing constituents within the reactor vessel, causing constituents to exit reactor vessel through the outlet, storing 1st portion of constituents in greater than or equal to 1 constituent storage devices (7013), circulating 2nd portion of constituents into inlet of reactor vessel, and contacting 2nd portion of constituents with the plasma; and    (2) plasma partial dissociation of carbonaceous materials which involves providing 1st apparatus consisting of 1st reactor vessel (703) having 1st inlet and 1st outlet, 1st plasma reactor having 1st divergent electrode and 1st divergent nozzle, 1st power supply, and 1st plasma reactor working gas source; providing 2nd apparatus consisting of 2nd reactor vessel (708) having 2nd inlet and 2nd outlet in which 2nd inlet is in fluid communication with 1st outlet and 2nd outlet is in fluid communication with 1st inlet, 2nd plasma reactor having 2nd divergent electrode and 2nd divergent nozzle in which 2nd divergent nozzle is in fluid communication with interior of 2nd reactor vessel, 2nd power supply, and 2nd plasma reactor working gas source; providing feed chamber (706) in fluid communication with 1st outlet and 2nd inlet; introducing 1st working gas from 1st working gas source into 1st plasma reactor; introducing 2nd working gas from 2nd working gas source into 2nd plasma reactor; adjusting 1st power supply to apply 1st voltage potential across 1st divergent electrode and 1st divergent nozzle to cause 1st working gas to partially dissociate and generate 1st plasma containing 1st constituents within 1st reactor vessel; adjusting 2nd power supply to apply 2nd voltage potential across 2nd divergent electrode and 2nd divergent nozzle to cause 2nd working gas to partially dissociate and generate 2nd plasma containing 2nd constituents within 2nd reactor vessel, causing 1st constituents to exit 1st reactor vessel through 1st outlet; introducing carbonaceous material into feed chamber; circulating portion of 1st constituents into feed chamber to make carbonaceous material contact with 1st constituents to form gaseous mixture; and circulating gaseous mixture into 2nd reactor vessel to make gaseous mixture contact with 2nd plasma to form effluent stream.
