A method for remediating contaminated soil and groundwater includes selecting a treatment material and creating a smolderable mixture of a contaminant, the treatment material, and soil.

A two-stage combustor having as constituent parts: a partial oxidation reactor, which catalytically converts a hydrocarbon fuel and a first supply of oxidant into a gaseous partial oxidation product; and a deep oxidation reactor having a premixer plenum fluidly connected to a porous heat spreader, which converts the gaseous partial oxidation product to deep oxidation products. In one embodiment, the premixer plenum provides an empty space wherein combustion occurs in flame mode. In a second embodiment, the premixer plenum contains a high pore density foam matrix, absent catalyst, which facilitates holding a flameless combustion downstream within the porous heat spreader. In both embodiments heat produced during combustion is transmitted from the heat spreader to an associated heat acceptor, such as a heater head of a Stirling engine.

The present invention relates generally to an apparatus for housing a chemical looping process comprising of at least one fluidized-bed combustor reactor, at least one entrained riser, at least one particle separator, optionally at least one particle holding reactor, at least one moving-bed reactor, at least one standpipe, at least one L-valve system for solid flow control and interconnecting sections.

A radiant burner for treating an effluent gas stream from a manufacturing processing tool includes a plurality of treatment chambers, each treatment chamber having an effluent stream inlet for supplying a respective portion of the effluent gas stream to that treatment chamber for treatment therewithin. In this way, multiple treatment chambers may be provided, each of which treats part of the effluent stream. Accordingly, the number of treatment chambers can be selected to match the flow rate of the effluent gas stream from any particular processing tool. This provides an architecture which is reliably scalable to suit the needs of any effluent gas stream flow rate.

A method for oxidizing a waste stream having hydrogen therein includes flowing the waste stream with hydrogen into an oxidant stream for mixing the streams in a proportion for providing a mixture below lower flammability limits (LFL), including the LFL of hydrogen; and introducing the mixed streams into a ceramic matrix bed of a flameless thermal oxidizer maintained at a temperature above auto-ignition temperature of the mixture. A related apparatus is also provided.

Methods are provided for the removal of sulfur and other ARD/AMD-generating materials through the smoldering combustion of an organic material. The methods comprise admixing an ARD/AMD-generating porous matrix material with an organic material to produce a mixture, exposing the mixture to an oxidant, and initiating a self-sustaining smoldering combustion of the mixture. Additional embodiments aggregate the organic material or ARD/AMD-generating porous matrix material or mixture thereof in an impoundment such as a reaction vessel, depression or matrix pile. Further embodiments utilize at least one heater to initiate combustion and at least one air supply port to supply oxidant to initiate and maintain combustion.
