Abstract: A distillation apparatus for use in microwave-assisted pyrolysis includes a microwave, a pyrolysis reactor, a microwave-absorbent bed, and a condenser. The pyrolysis reactor is located within the microwave and configured to receive a liquid input stream and to output a vapor. The microwave-absorbent bed is located within the pyrolysis reactor that converts microwave energy provided by the microwave to thermal energy to initiate pyrolysis within the pyrolysis reactor, wherein the pyrolysis reactor provides a vapor output. The condenser is configured to receive the vapor output of the pyrolysis reactor and to cool and condense the vapor into a recoverable product.

Abstract: Disinfecting particulate material includes combining the particulate material with a photocatalyst to yield a mixture, irradiating the mixture for a length of time with pulses from a light source having broadband emission spectrum between 190 nm-1100 nm to yield an irradiated mixture, and separating the photocatalyst from the disinfected mixture to yield the disinfected particulate matter. Irradiating the mixture inactivates microorganisms in the mixture to yield a disinfected mixture. A system for disinfecting particulate material includes a pulsed light source having a broadband emission spectrum in a range between about 190 nm and about 1100 nm, a chamber defining a cavity optically coupled to the pulsed light source, a humidifier, a fan, and one or more sensors. The chamber includes a conveyor configured to accept the particulate material and arranged such that the pulses emitted by the pulsed light source irradiate the particulate material on the conveyor.
