NOVELTY - Gasifying (M1) carbonaceous feedstock involves pyrolyzing the feedstock to produce a gas product and a solids product, where the gas product includes methane and noxious chemicals; and removing at least some of the noxious chemicals from the gas product using activated carbon as a filtering medium, the removing step occurs at a controlled temperature.    USE - For producing methane gas and carbon products e.g. composite lumber product and non-wetting carbon having pores fused with silica from carbonaceous feedstock e.g. coal biomass and municipal solid waste (claimed). The non-wetting carbon products are useful as filler material and binder.    ADVANTAGE - The method is clean, efficient for gasification of coal to globally reduce the dependence on oil drilled and pumped from the Earth's crust. The method provides combined cycle continuous high temperature pyrolysis system that utilizes the waste heat of the continuous high temperature pyrolysis system to fuel the low temperature technologies. The system having multiple chambers in the high-temperature pyrolysis unit allows the high-temperature pyrolysis unit to process a wide range of feedstocks without costly modification or recalibration of the system; pyrolyze different feedstock material in the high-temperature pyrolysis unit without interruption of the continuous operation of the high-temperature pyrolysis unit since the temperature can be monitored. The non-wetting carbon has nearly complete resistance to absorption of other materials, as well as nearly complete resistance to moisture. The plastic lumber product produced exhibit the properties of waterproof, fungus and mildew resistant and having a low physical expansion coefficient to heat and moisture.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) system for gasification comprising a pyrolysis unit including a heater and a conveyor for transporting the carbonaceous feedstock through the heater; a resultant chamber disposed downstream of the pyrolysis unit for separating gaseous and solid pyrolysis products; unit adjusting the temperature of the solid pyrolysis products disposed downstream of the resultant chamber; and a filter for sequestering noxious materials from the gaseous pyrolysis products disposed downstream of the temperature adjusting unit, where the filter uses at least some of the solid pyrolysis products to filter at least a portion of the gaseous pyrolysis products; and    (2) a composite lumber product comprising a plastic member and a filler material composed of a non-wetting carbon in which pores have been opened via a continuous high-temperature pyrolysis process and then fused with silica.
