ABSTRACT:
The invention provides a practical and efficient method and apparatus for thermally processing organic based raw materials of either primary or secondary (recycled) origin, in order to extract volatile organic vapors and to selectively produce either condensable hydrocarbon gases or, more preferably, non-condensable synthesis gases that are rich in hydrogen and carbon monoxide for use as a raw material in chemical processes, or as a fuel. In particular, the invention provides a single rotary reactor having two contiguous hearth reaction areas, i.e., a drying and volatizing area and a reformation area, the areas being separated from each other by a bed-retaining refractory weir. The weir has an aperture for fluidly connecting the two hearth reaction areas of the single reactor. In each of the two reaction areas, the temperature, pressure, and chemical characteristics of the internal gaseous atmosphere can be selectively controlled to achieve the degree of volatizing, cracking, dissociation and/or reforming of vaporous hydrocarbon gases required to meet the desired operating objective. Thus, a variety of synthesis gases having differing degrees of richness in hydrogen and carbon monoxide may be produced in a single reactor, eliminating the need for a downstream secondary reformation or "finishing" reactor.
