A continuous flow treatment apparatus comprises a heating fluid management portion and a feces treatment portion. The heating fluid management portion is configured to heat heating fluid and provide the heated heating fluid to a heat exchanger. The feces treatment portion comprises the heat exchanger. The heat exchanger is configured to receive feces at a first position of the heat exchanger, indirectly heat the feces via the heated heating fluid as the feces are transported from the first position to a second position of the heat exchanger, and provide the heated feces at the second position. The feces are maintained at a minimum temperature for a predetermined amount of time such that the feces exiting the feces treatment portion have been rendered sanitary for at least one of storage or further processing.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce ethanol and/or butanol, e.g., by fermentation.

Methods and systems are described for processing cellulosic and lignocellulosic materials into useful intermediates and products, such as energy and fuels. For example, conveying systems and methods, such as highly efficient vibratory conveyors, are described for the processing of the cellulosic and lignocellulosic materials.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.

A system and method are described for heating a substance (i.e., liquid, gas, and/or an absorbed solid) using a carbon nanostructured porous foam as a heat transfer material and an electronic heat source. In some embodiments, the heat source may be a microwave volumetric heating (MVH) system. The method for heating, vaporizing, or decomposing any of the desired substance may involve filtering or continuously flowing the substance through the carbon nanostructured porous foam heat transfer material, resulting in physical confinement or absorption of the substance, and subjecting the carbon nanostructure porous foam heat transfer material to sufficient electronic radiation.

Materials, such as biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. Conveying systems, such as flowing gas conveying systems and such as closed-loop flowing gas conveying systems are described.

A process for converting light alkanes from a natural gas production stream to higher molecular weight hydrocarbons is provided. The method includes transporting the natural gas stream to an electron beam reactor, such as a steel flow-type radiation reactor connected hermetically to an accelerator beam window. The gas stream is exposed to electron beam radiation to generate an upgraded and substantially liquefied hydrocarbon stream. The method then includes transporting the substantially liquefied hydrocarbon stream into a scrubber to remove non-condensed gases. The remaining liquid hydrocarbon stream is then transported as condensate to a distillation tower, where high octane products are separated through fractionation.

Materials (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems equipment, and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, using an array of vaults.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the equipment is protected from radiation and hazardous gases by equipment enclosures. The equipment enclosures may be purged with gas.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, while cooling equipment and the biomass to prevent overheating and possible distortion and/or degradation. The biomass is conveyed by a conveyor, which conveys the biomass under an electron beam from an electron beam accelerator. The conveyor can be cooled with cooling fluid. The conveyor can also vibrate to facilitate exposure to the electron beam. The conveyor can be configured as a trough that can be optionally cooled.
