TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: In (M1), the removing step includes several filtering steps in which at least some of the noxious chemicals in the gas product are removed using activated carbon as a filtering medium; the filtering steps are performed using activated carbon at different temperatures. The pyrolysis step produces a solids product including activated carbon and the removing step includes using at least some of the activated carbon from the pyrolysis step as a filtering medium; the removing step includes controlling a temperature of the activated carbon so that the filtering steps are performed using activated carbon at different temperatures. The pyrolysis step includes conveying the feedstock through a pyrolysis chamber using an auger disposed within a retort (preferably rotating the retort in a direction opposite a direction of rotation of the auger). The method (M1) further involves maintaining a positive pressure in the retort includes monitoring a pressure in the pyrolysis chamber and varying a negative pressure created by a blower to adjust the pressure in the pyrolysis chamber; and injecting steam into the feedstock upstream of the retort. The gas product produced by the pyrolysis step includes carbon nanostructures. The method further involves collecting at least some of the carbon nanostructures before the removing step. The collecting step is performed by imposing an electrostatic charge on the carbon nanostructures and using an electrically charged plate to gather the charged carbon nanostructures; pyrolysis of coal separately from at least one of biomass and municipal solid waste feedstock to produce a gas product including methane and noxious chemicals, and using at least some of the activated carbon from the pyrolyzing a biomass or municipal solid waste to remove at least some of the obnoxious chemicals from the gas product created during the pyrolyzing coal; running a low temperature liquefaction process using heat from the pyrolyzing step. The low temperature liquefaction process includes at least one of a coal liquefaction process and a vacuum distillation process. Preferred System: The temperature adjusting unit includes a cooling/heating jacket encasing the solid pyrolysis products. The conveyor includes an auger and a retort, the auger is rotatably disposed in the retort and the retort is rotatable in a direction counter to a direction of rotation of the auger. The heater includes multiple heating chambers (preferably burner and an exhaust laterally offset and perpendicular to a longitudinal axis of the auger retort so as to create a flow of heat around the auger retort). The conveyor includes an auger, and the auger includes a shaft, and further comprising a vapor barrier seal including at least two vapor barrier collars disposed around the shaft and a detecting chamber for sensing resultant gases disposed between the vapor barrier collars. The system further comprises unit for maintaining the resultant chamber at a pressure greater than atmospheric pressure. The pressure maintaining unit includes a blower located downstream of the resultant chamber. The blower is disposed downstream of the filter. The solid pyrolysis product includes activated carbon and the filter includes an activated carbon bed. The activated carbon in the activated carbon bed is a resultant of pyrolysis of a carbonaceous feedstock. The system additionally comprises a second auger disposed within a tubular member for conveying the activated carbon from the resultant chamber to the activated carbon bed; several filters. The temperature adjusting unit comprises a cooling/heating jacket surrounding the tubular member; several cooling/heating jackets surrounding the tubular member, where each of the several cooling/heating jackets precedes one of the filters; dust clarifier downstream of the resultant chamber for removing carbon nanostructures from the resultant gases. The pyrolysis unit is a high-temperature pyrolysis unit that produces waste heat, and further comprising a low-temperature pyrolysis unit configured to operate using the waste heat from the high-temperature pyrolysis unit. The high-temperature pyrolysis unit is a first high-temperature pyrolysis unit configured to pyrolyze at least one of a biomass and municipal solid waste to produce activated carbon, and further comprises a second high-temperature pyrolysis unit configured to pyrolyze a feedstock that does not create activated carbon, and unit for filtering gaseous pyrolysis products from the second pyrolysis unit using activated carbon from the first pyrolysis unit.
