Definitions
- U.S. Patents 4,574,714 and 4,602,574 to Bach exemplify the single reaction zone molten iron gasifier
- U.S. Patent 1 ,803,221 to T rer U.S. Patent 4, 1 87,672 to Razor
- 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
- FEED MATERIALS Natural Gas (CH 4 ), liquified petroleum gas (LPG), propane, petroleum naphtha, light or heavy distillate, vacuum and other resids, solvent deasphalted pitch (SDA), aromatic extracts, FCC slurry oil, trash, garbage, tires, coal, virtually any other hydrocarbon-ct ntaining material.
- CH 4 Natural Gas
- LPG liquified petroleum gas
- propane petroleum naphtha
- light or heavy distillate vacuum and other resids
- solvent deasphalted pitch (SDA) solvent deasphalted pitch
- aromatic extracts FCC slurry oil, trash, garbage, tires, coal, virtually any other hydrocarbon-ct ntaining material.
- 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.
