A radial flow oil shale retort can include a central heating fluid conduit having a permeable outer wall and an outer heating fluid annulus positioned about the central heating fluid conduit, the outer heating fluid annulus having a permeable inner wall. An annular body of comminuted oil shale can be between the permeable outer wall of the central heating fluid conduit and the permeable inner wall of the outer heating fluid annulus. A heating fluid supply can be connected to either the central heating fluid conduit or the outer heating fluid annulus to flow a heating fluid in a radial direction through the annular body of the comminuted oil shale.

The present invention is directed to a pyrolysis method. The method involves providing a biomass and subjecting the biomass, in a reactor operating under conditions of parasitic heat loss of less than 1% of the biomass' chemical energy content, to partial oxidation where, during steady state operation of the reactor, oxygen is provided to the reactor in sufficient quantity to achieve an equivalence ratio of 0.06 to 0.15 to release sufficient energy to support endothermic pyrolysis reactions and produce condensable organic compounds as the major portion of the pyrolysis products.

The production of biochar generates syngas, VOCs, CO and other gasses that can adsorb to biochar and reduce the quality of the final product. A controller measures the operating parameters, such as temperature, pressure and oxygen level, and automatically controls a feedstock auger motor, blower(s) and other subsystems of a continuous combined heat, power and biochar carbonizer. The carbonizer pyrolyzes feedstock. A catalytic converter combusts unburned components in by-product gases and generates additional thermal energy. Thermal energy drives an engine, such as a Sterling, steam, or ORC engine, to generate electricity or operate a mechanical device. Remaining thermal energy is transferred using another medium, such as air or water, via a heat exchanger. The feedstock is purposefully incompletely combusted, to produce biochar that consists largely of carbon. The biochar may be used to augment soil for cultivation, filtration or for other purposes. Some embodiments condense water from the exhaust to provide potable water.

Methods and systems are disclosed for improving the efficiency and reducing the carbon intensity of transportation fuels produced from heavy oil extracted with the steam injection process, by replacing natural gas from fossil fuel sources with a substitute renewable gas produced from solid carbonaceous materials while co-producing a solid carbonaceous byproduct.

The method and system for recycling waste including plastic waste of the present invention includes a carbonizing step in which waste including disused plastic products such as PET bottles is carbonized in a carbonization furnace in which the temperature is raised in stages multiple times.

The present invention concerns an arrangement for the recycling of carbon and hydrocarbon compounds from organic input material through pyrolysis treatment, comprising: a reactor (1) comprising a chamber (110) that is limited by a jacket (111) and upper and lower end-wall sections (112, 113), in which chamber input material (M) in fragmented form is intended to be introduced, gas inlet means (120) for the supply of heated inert gas (101) to the input material, whereby the gas inlet means (120) is connected in a manner that transfers gas to a gas emission source (102) through inlet pipes (104, 129, 187.1, 187.2) that are associated with inlet pipes, and gas outlets (160) for leading the gas out of the chamber, where the gas outlet means (120) comprises openings (125, 146, 155, 185) through which gas flows intended to supply the gas (101) into the chamber (110), whereby the openings (125, 146, 155, 185) through which gas flows are arranged such that a fall in pressure dP is generated during the supply of gas that exceeds the fall in pressure dM of the gas during passage through the input material M that has been introduced into the chamber. The invention concerns also a method for the recycling of carbon and hydrocarbon compounds from organic input material through pyrolysis.
