Abstract: A processing vessel is loaded with a feedstock including organic material and at least one additive which is non-inert to the organic material. A bottom portion of the feedstock is heated to a pyrolytic state for producing a horizontal thermal layer within the feedstock which thermally decomposes organic material into carbon as the non-inert additive reacts with the organic material. Vapor is directed downwardly through the feedstock while discharging volatile organic compounds from a lower portion of the chamber. Prior to complete thermal decomposition of the feedstock, the direction of vapor flow within the feedstock is reversed wherein the vapor flows upwardly through the feedstock while the volatile compounds are discharged from an upper portion of the chamber. Pressure and vapor flow within the chamber are regulated during upward vapor flow to regulate vertical movement of the thermal layer within the feedstock for controlling the extent of thermal decomposition of the feedstock.

Abstract: The present invention relates to the field of atomizing fluids. Some embodiments described herein relate to a nozzle for atomization of one fluid in an exhaust system of a combustion engine or gas turbine, the nozzle comprising an inlet and two or more outlets, arranged so that fluid streams discharged from the two or more outlets impinge at a distance from the two or more outlets so that the fluid streams discharged from at least two of the two or more outlets impinge each other at a specified angle in the range of 70° to 95° so as to provide a spray by atomization of the fluid. The fluid streams may e.g. have a cross section in the order of 0.005 to 0.05 mm2 before impingement.

Abstract: A system and process for gasification of a carbonaceous feedstock uses pyrolysis to produce a gas product, which may include methane, ethane, and other desirable hydrocarbon gases, and a solids product, which includes activated carbon or carbon. The gas product may then be filtered using at least a portion of the activated carbon from the solids product as a filtering medium. In an embodiment, at least some of the noxious chemicals are sequestered or removed from the gas product in one or more filtering steps using the activated carbon as a filtering medium. In a further embodiment, the filtering steps are performed in stages using activated carbon at different temperatures. A high-temperature pyrolysis system that produces activated carbon may be combined with another high-temperature pyrolysis system that does not produce activated carbon to provide filtering of noxious compounds using activated carbon from the first high-temperature pyrolysis system.
