Abstract: A method for remediating a contaminated porous matrix including selecting the type and quantity of organic fuel to create a smolderable mixture of the organic fuel and contaminated porous matrix, and controlling the rate of oxidant addition to manipulate the relative proportions of oxidative breakdown products, non-oxidative breakdown products, and non-destructive remediation processes. The method further involves collecting the volatilized contaminant, and any gaseous breakdown products of the contaminant.

Abstract: Methods are provided for generating or recovering gaseous materials such as hydrogen and solids such as metals through the smoldering combustion of an organic material. The methods include admixing a porous matrix material with an organic material, and, in some embodiments a catalyst, to produce a porous mixture. The mixture is exposed to an oxidant, initiating a self-sustaining smoldering combustion of the mixture, and collecting the vapors and combustion products or processing the porous matrix following combustion to physically separate the porous matrix material from ash containing inorganic materials of value. Additional embodiments aggregate the organic material or catalyst or porous matrix material or mixture thereof in an impoundment such as a reaction vessel, lagoon 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.
