• Figure 2 is a plot of the percent purity of hydrogen product gas versus time for the swing system of Figure 1, wherein cyclically, when hydrogen is nearly zero percent, then a CO (of CO and possibly C0 2 ) is near 100%, and vice versa.
• Figure 3 is an exploded, perspective view of one of the individual reactors of

• the swing can be controlled on the basis of elapsed time, mass fed, percent carbon in molten metal, product purity, or other variables
• Each reactor or crucible preferably consists of a pressure-tight steel housing supporting internally segmented refractories for simplicity in construction and the reduction of thermal expansion effects during reactor operation.
• an inlet lance or sparging tube feeds hydrocarbon material downwardly through a vapor space above the molten metal for discharge at a distal end submerged within the molten metal while the head of the reactor or crucible is provided with a product gas outlet which emits product gases during reactor operation.
• swing valves are located downstream of gas product heat exchangers within such product outlet for lower temperature operation and longer life of the swing valve.
• the system may be timer operated with switching from hydrogen production to carbon monoxide production every several minutes.
