Abstract: A novel photocatalytic oxidation system that combines long lifetime, high-power light emitting diodes (LEDs) with efficient, visible light-activated photocatalysts for the destruction of Volatile Organic Compounds (VOCs) and other pathogens in air and water flow systems under ambient conditions of temperature and pressure is described. The technology uses the combination of visible photocatalysts with robust visible LEDs, uniform side emission fiber optics, and efficient catalyst surface illumination technologies to create a photocatalytic oxidation unit for air and water purification. This combined approach leads to numerous performance benefits including high VOC conversion efficiency, compact reactor volume, low pressure drop, and the elimination of conventional ultraviolet (UV) mercury lamp logistics and hazards.

Abstract: This invention pertains to the non-catalytic oxygenated steam reforming of organic matter to produce a gas mixture rich in hydrogen, carbon monoxide and carbon dioxide. The reforming gas is used for production of methane, methanol, dimethyl ether, oxygen, carbon dioxide, and other compounds via downstream processing catalytic gas-phase processes and electrolysis. The reforming gas may also be combusted directly for electricity generation.

Abstract: Novel methods for capturing carbon dioxide from internal combustion engines, gas turbines, and other combustion sources operating on a wide range of gaseous, liquid, or solid fuels are described. Capturing carbon dioxide from combustion exhaust on an absorbent and then regenerating the absorbent for recovery, storage, use, or sequestration of concentrated carbon dioxide are described herein.
