摘要： Gaseous carbon compounds can be converted to carbon neutral or negative products using biological processes to metabolise the gaseous carbon compounds or use thermochemical processes to convert gaseous carbon compounds to syngas followed by thermochemical or biological processes to produce products. The gaseous carbon compounds include a mixture of CO2 and CH4 from either a single source, or two or more different sources. Separate biological processes are incorporated to process different gaseous carbon compounds. A gaseous carbon compound produced as a by-product of one biological process can be used as at least part of the feedstock for another process. A renewable energy system can be provided to power equipment. A control system can be used to control flow of gaseous carbon compounds and reactants entering the entire carbon processing systems to provide mass balanced quantities of gaseous carbon compounds and reactants in each processing system and/or between processing systems.

摘要： The disclosure provides a platinum-containing three-way conversion (TWC) catalyst, and a system for treating an exhaust gas stream from a gasoline engine using the TWC catalyst. The system is configured to introduce controlled quantities of hydrogen gas into the exhaust gas stream upstream of the platinum-containing TWC catalyst article during a cold-start period. Further provided are related methods of treating such exhaust streams. Such systems and methods are useful in reducing a level of one or more of hydrocarbons, carbon monoxide, and nitrogen oxide in a gaseous exhaust stream from a gasoline engine.

摘要： A system and method of abating air pollution and stimulating crop growth. A reagent is introduced to a crop canopy to neutralize air pollutants within said canopy, wherein the reagent induces an oxidation-reduction chemical reaction with the air pollution present throughout the acreage of crops, and by means of the reaction effectually neutralizes the harmful effects of the air pollutants on the crops. The reagent is diluted using a venturi valve or other means. The flow rate of said reagent is regulated using an electronic control unit, based on data collected from at least one type of sensor in the canopy that is in communication with the control unit.

摘要： Embodiments of the present disclosure generally relate techniques for abating N2O gas present in the effluent of semiconductor manufacturing processes. In one embodiment, a method includes injecting hydrogen gas or ammonia gas into a plasma source, and an effluent containing N2O gas and the hydrogen or ammonia gas are energized and reacted to form an abated material. By using the hydrogen gas or the ammonia gas, the destruction and removal efficiency (DRE) of the N2O gas is at least 50 percent while the concentration of nitric oxide (NO) and/or nitrogen dioxide (NO2) in the abated material is substantially reduced, such as at most 5000 parts per million (ppm) by volume.

摘要： A plasma abatement process for abating effluent containing compounds from a processing chamber is described. A plasma abatement process takes gaseous foreline effluent from a processing chamber, such as a deposition chamber, and reacts the effluent within a plasma chamber placed in the foreline path. The plasma dissociates the compounds within the effluent, converting the effluent into more benign compounds. Abating reagents may assist in the abating of the compounds. The abatement process may be a volatizing or a condensing abatement process. Representative volatilizing abating reagents include, for example, CH4, H2O, H2, NF3, SF6, F2, HCl, HF, Cl2, and HBr. Representative condensing abating reagents include, for example, H2, H2O, O2, N2, O3, CO, CO2, NH3, N2O, CH4, and combinations thereof.
