Abstract: A process for the pyrolysis of at least one material includes: introducing the material into a pressurized rotary retort system, heating the material in the pressurized rotary retort system within a desired temperature range and within a desired pressure range for a desired period of time; and, advancing the heated and pressurized material from a first end to a second end of the pressurized rotary retort by rotating the pressurized retort about its longitudinal axis; where at least a quantity of the material is converted into one or more end products. Also the system generally includes: a pressurized rotary retort system configured for producing at least one gaseous product from pyrolysis of material, and having a pressurized furnace vessel and a retort positioned within the pressurized furnace vessel; and; a solids reactor system operatively connected to the rotary retort for receiving material from the pressurized rotary retort system.

Abstract: System(s) and process(es) are provided to produce synthesis gas from feedstock through, in part, multi-phased gasification and steam reformation. In the multi-phased gasification, an amount of feedstock is supplied to a pyrolysis chamber in which high-pressure pyrolysis at a first temperature reforms into gas at least a portion of the amount of feedstock; the gas includes synthesis gas (syngas). An amount of feedstock by-product that results from the high-pressure pyrolysis is conveyed to a solids reactor functionally coupled to the pyrolysis chamber. At least a portion of the amount of feedstock by-product is reformed into syngas at high-pressure and a second temperature within the solids reactor; an amount of disposable solids is ejected from the solids reactor. Gas produced in the pyrolysis chamber or syngas produced in the solids reactor is saturated via steam reformation and cleaned. Clean syngas is supplied for fuel production.
