Abstract: A novel process can be used for producing methacrylates such as methacrylic acid and/or alkyl methacrylates, in particular MMA. The process leads to an increased yield and increased efficiency compared to other C4-based production processes, in particular processes starting from isobutylene or tert-butanol as raw material. The process can be operated for longer periods without disruption and with the same or even increased activities and selectivities. The process can also be executed in a manner that is as simple, cost-effective, and environmentally friendly as possible.

Abstract: Methods of making an iron based catalyst using microwave hydrothermal synthesis are provided. The methods include dissolving iron(III) nitrate, Fe(NO3)3, in an organic solvent to form a solution. Once dissolved, the methods include a step of neutralizing the solution with an alkaline mineralizing agent to obtain a precipitate. The solution with the precipitate is then subjected to microwave radiation to cause a temperature gradient and a hydrothermal crystallization process to form a synthesized product. The synthesized product is subsequently separated from the mineralizing agent. The method includes washing and drying the synthesized product to obtain particles of sodium iron oxide (NaFeO2) catalyst that can be used as a composition for a passive NOx adsorber. A two-stage NOx abatement device for removal of NOx from an exhaust gas stream during a cold start operation of an internal combustion engine is also provided.

Abstract: As a visible-light-responsive photocatalytic-titanium-oxide-particulate dispersion liquid that can achieve a high visible light activity and is of a type different from the related art, the present invention provides a visible-light-responsive photocatalytic-titanium-oxide-particulate dispersion liquid in which two types of titanium oxide particulates are dispersed in an aqueous dispersion medium. The two types of titanium oxide particulates are first titanium oxide particulates, in which a tin component and a transition metal component (but excluding an iron-group component) for enhancing visible light responsiveness are dissolved, and second titanium oxide particulates, in which an iron-group component is dissolved. When a photocatalytic film formed by using this dispersion liquid is used, a high decomposition activity is achieved even in a case where a decomposition substrate has low concentration, which was previously difficult under visible light conditions.
