An improved method of producing carbon monoxide in a plasma arc reactor is disclosed, wherein carbon dioxide is delivered to an arc to form a plasma into which solid carbon is delivered. The products are quenched and filtered to yield carbon monoxide. High yields of carbon monoxide of high purity and high efficiencies of electrical-to-chemical conversion thus may be achieved.

Production of carbon monoxide in a plasma arc reactor

A wire-feeding mechanism comprises a rotatably mounted pulley formed on its edge with a continuous circumferential groove and plural rollers arranged to hold an endless flexible belt against a segment of the edge of the pulley. The belt thus is adapted to hold the wire in the groove as one roller is driven.

An electric arc welding system includes a welding torch having a head supporting a nonconsumable, elongated electrode for establishing an arc and between a work piece and an outer end of the electrode. The system further includes nozzle means for supplying an inert gas shield around the longitudinal axis of the electrode and said arc and conductor means for supplying current to the electrode for establishing and maintaining the arc. Means are provided for feeding filler wire toward the longitudinal axis of the electrode and the arc along a feed path intersecting the axis at an acute angle. The feeding means includes means for advancing the filler wire along the feed path in repetitive incremental strokes separated by alternating periods of stationary dwell.
