A multiple stage synthesis gas generation system is disclosed including a high radiant heat flux reactor, a gasifier reactor control system, and a Steam Methane Reformer (SMR) reactor. The SMR reactor is in parallel and cooperates with the high radiant heat flux reactor to produce a high quality syngas mixture for MeOH synthesis. The resultant products from the two reactors may be used for the MeOH synthesis. The SMR provides hydrogen rich syngas to be mixed with the potentially carbon monoxide rich syngas from the high radiant heat flux reactor. The combination of syngas component streams from the two reactors can provide the required hydrogen to carbon monoxide ratio for methanol synthesis. The SMR reactor control system and a gasifier reactor control system interact to produce a high quality syngas mixture for the MeOH synthesis.

Disclosed herein is a field replaceable multifunction cartridge for the conversion of composite high molecular weight hydrocarbon vapors, extracted from homogenous or heterogeneous, segregated or unsegregated, wet or dry, unclean miscellaneous multi-feed waste input, to produce low molecular weight fractions of industriously combustible fuel products through catalytic cracking. The multifunction cartridge system is constructed in a modular fashion is capable of performing the catalytic, cleaning and scrubbing functions through the temperature range ranging from ambient to 500 C., owing to the high mechanical strength, low coefficient of expansion, resistance to thermal fatigue etc.

A process and system for the treatment of solid waste based on a temperature gradient generated by two distinct thermal sources, notably of a sequenced technological assembly, is able to process solid waste of any class, which operates through a reactor (1) having two chambers (2 and 3), each having a thermal source (4 and 5), where a thermal gradient is generated, followed by a heat exchanger (6) where gases are abruptly cooled and taken to a neutralizing tank (7), for then being directed to an activated charcoal filter (8), due to the action of a blower (9), before finally entering a burner (10) that works under electrical discharges, passing through a catalytic converter (11) and chimney (12) where it is extravasated into the completely inert atmosphere.

This invention relates to a power recovery process in waste steam/CO.sub.2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

Provided are a method for manufacturing syngas including the steps of (S1) heat-treating organic waste in a first reactor to produce a first mixed gas; (S2) introducing the first mixed gas to a second reactor and subjecting it to methane reforming in the presence of a catalyst to produce a second mixed gas; (S3) separating the catalyst and carbon dioxide from the second mixed gas and recovering a third mixed gas from which the catalyst and the carbon dioxide have been removed; (S4) converting the carbon dioxide separated in step (S3) into carbon monoxide through a reverse Boudouard reaction in a third reactor; and (S5) mixing the third mixed gas recovered in step (S3) and the carbon monoxide converted in step (S4) to produce syngas, and an apparatus for manufacturing syngas.

The present disclosure relates to a power production system that is adapted to achieve high efficiency power production with complete carbon capture when using a solid or liquid hydrocarbon or carbonaceous fuel. More particularly, the solid or liquid fuel first is partially oxidized in a partial oxidation reactor. The resulting partially oxidized stream that comprises a fuel gas is quenched, filtered, cooled, and then directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO.sub.2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The expanded and cooled exhaust stream is scrubbed to provide the recycle CO.sub.2 stream, which is compressed and passed through the recuperator heat exchanger and the POX heat exchanger in a manner useful to provide increased efficiency to the combined systems.

Improved two-stage entrained-flow gasification systems and processes that reduce the cost and complexity of the design and increase the reliability, while maintaining the efficiency by implementing a first chemical quench followed by a second water quench of the produced syngas. The quenched syngas is maintained above the condensation temperature of at least one condensable component of the syngas, allowing residual particulates to be removed by dry particulate filtration.

A downdraft gasifier for producing a gaseous fuel to be used in an engine from a carbonaceous material with a pyrolysis module, a reactor module, and a heat exchanger system that cooperate to produce the gaseous fuel from the carbonaceous material and to extract particulates from the gaseous fuel from the reactor. The heat exchange system includes a first heat exchanger coupled to the dryer module that heats the carbonaceous material with the gaseous fuel output of the reactor module to dry the carbonaceous material; a second heat exchanger coupled to the pyrolysis module that heats the dried carbonaceous material with the exhaust from the engine to pyrolyze the dried carbonaceous material into tar gas and charcoal; and a third heat exchanger coupled to the reactor module that heats air used to combust the tar gas with the gaseous fuel output of the reactor module to preheat the air.

A gasification system includes a scrubber in communication with a particulate removal subsystem and a quench sub-system.
