Pyrolysis reactor with optimized reaction sequencing
System and method for processing pyrolyzable materials in order to recover usable end products are disclosed. The pyrolysis process comprises a number of stages. First pre-treating is to reduce moisture content to approximately 15%. Second is to optimize the volatile organic under the heat and vacuum. This treatment stage is carried out at the temperature between 350 to 400 C. Next, the material is treated with heat and vacuum to produce hot gas and solid carbon residue. This stage is carried out at the temperature up to 800 C. The solid carbon residue can be separated from the hot gas, the volatile organic materials condensed to produce liquid hydrocarbon and gas products. Pyrolysis processes and system according to the present invention are able to thermally decompose carbon-containing materials, including, but not limited to, tires and other rubber-containing materials, hydrocarbon-containing products including pyrolysis oil, used oil and lubricants, organic wastes and alike, carbon containing minerals like brown and bituminous coal, oil shale and oil bearing schists. System and pyrolysis methods according to aspects of the present invention may be successful on a commercial scale.
Combined hydrothermal liquefaction and catalytic hydrothermal gasification system and process for conversion of biomass feedstocks
A combined hydrothermal liquefaction (HTL) and catalytic hydrothermal gasification (CHG) system and process are described that convert various biomass-containing sources into separable bio-oils and aqueous effluents that contain residual organics. Bio-oils may be converted to useful bio-based fuels and other chemical feedstocks. Residual organics in HTL aqueous effluents may be gasified and converted into medium-BTU product gases and directly used for process heating or to provide energy.

Pyrolysis Reactor System and Method
A system and method for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor having a pyrolysis conduit and a solids return conduit segment. Each segment is configured with an outlet and an inlet to receive and discharge solid materials that are circulated through the reactor through the different segments. A solids conveyor is disposed within the pyrolysis conduit segment to facilitate conveying solid materials from the solids inlet upward through the pyrolysis conduit segment toward the solids discharge outlet. A pyrolysis feedstock is introduced into the pyrolysis reactor and at least a portion of the feedstock is converted to pyrolysis gases within the pyrolysis conduit segment, which are discharged through a gas outlet. An eductor condenser unit with an eductor assembly having a venturi-restricted flow path for receives a pressurized coolant fluid. A second flow path for receiving the discharged pyrolysis gases intersects the venturi-restricted flow path so that the received pyrolysis gases are combined with the coolant fluid and are discharged together to a mixing chamber that is used to condense pyrolysis gases.

FAST PYROLYSIS HEAT EXCHANGER SYSTEM AND METHOD
A fast pyrolysis heat exchanger system for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As a granular solid heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials.

Method of and system for grinding pyrolysis of particulate carbonaceous feedstock
A pyrolysis plant 20 comprises a grinding pyrolyzer 22, being a machine or apparatus in which both particle size reduction and pyrolysis occur simultaneously. Plant 20 also comprises a bin (hopper) 30 for holding wet particulate biomass feedstock. Chute 32 leads from the bin 30 to a biomass dryer 34 which reduces moisture content of the feedstock as low as possible, e.g., to below about 10. Dried feedstock is conveyed from dryer 34 via line 36 to a dried biomass feedstock hopper 38. Dried feedstock is fed from hopper 38 into a chute 40 which leads to an inlet trunnion 42 of grinding pyrolyzer 22. A discharge trunnion 44 of grinding pyrolyzer 22 leads to a char holder 60 for collecting char particles and a condensation train 62 for condensing vapor generated by the pyrolysis to produce oil.
