## Abstract

In a process for manufacturing gas from hydrogen-bearing starting materials—such as those also containing carbon, carbonaceous materials, hydrocarbons or other hydrogen-bearing materials—the starting materials are fed into a 3-dimenstional plasma region to produce two output streams: a gas substantially containing hydrogen, and a by-products stream. Apparatus and a method are disclosed for generating gas which is substantially hydrogen gas (but may also contain other gaseous species) from the essentially complete dissociation of the starting materials in a plasma operating under pyrolytic conditions.1 Starting materials are fed into a plasma reactor. These starting materials are heated by one or more disclosed plasma sheets and/or plasma arrays in a reactor. The manufactured gas is vented from the reactor through an outlet. By-products are also removed from the reactor after being processed to remove the manufactured gas constituents. In addition, organic and inorganic matter that is input to the plasma is rendered ecologically and biologically safe and the by-products are extracted from the reactor for disposal (e.g., carbon sequestering) or to be recycled into various uses (e.g., ceramic tiles, carbon black, carbon nanotubes,2 pyrolytic graphite, for insulation and road paving materials).

## Claims

### Claim at position 1

1: A plasma sheet as a means for the manufacture of gas by pyrolytic heating, gasifying and dissociation of large volumes of starting materials.

### Claim at position 2

2: A plasma array as another means for the manufacture of by pyrolytic heating, gasifying and dissociation of large volumes of starting materials.

### Claim at position 3

3: A process for the high-volume, high mass-flow rate manufacture of gas by pyrolytic heating, gasifying and dissociation of large volumes of starting materials using either of the disclosed inventions or similar means.
