摘要： In one aspect, the disclosure relates to an oxide-molten salt (OMS) composite material offering excellent energy storage capacity at low cost. The OMS composite material can be provided in at least three forms, including a porous, perovskite-oxide particle as a matrix having pores filled with unary salt or salt mixtures; an external shell of perovskite-oxide particles and an internal core of salt or a salt mixture; and/or a porous, perovskite-oxide particle as a matrix filled with unary salt or salt mixtures, wherein the whole particle is enclosed with an oxide outer shell. Further in this aspect, the outer shell can be dense but either mixed ionic-electronically conductive or porous. In another aspect, the disclosed methods and systems can be used for grid-scale energy storage by retrofitting existing steam turbine-based power plants and concentrated solar plants. In a further aspect, the disclosed methods, systems, and materials are environmentally benign.

摘要： Acrolein is produced by selectively oxidizing iso-propanol over a first mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The first mixed metal oxide catalyst comprises oxides of molybdenum and bismuth. Acrylic acid is produced by selectively oxidizing the acrolein over a second mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The second mixed metal oxide catalyst has a different composition from the first mixed metal oxide catalyst.

摘要： The present invention is a perovskite metal oxide catalyst substituted with metal ions for reducing carbon deposition, a method for producing the same, and a process for performing a methane reforming reaction using this catalyst. The catalyst is produced in which Ni in ionic form is substituted at a portion of the Ti site of SrTiO3, MgTiO3, CaTiO3, or BaTiO3, which is a multi-component metal oxide having a perovskite structure. Then, various methane reforming reactions (steam-methane reforming, dry reforming of methane, catalytic partial oxidation of methane) may be efficiently and economically performed using this catalyst. The nickel-substituted perovskite metal oxide catalyst has a structure in which Ni2+ is substituted in the perovskite lattice structure. Thus, the metal oxide catalyst has advantages in that carbon deposition thereon does not occur, and thus, the catalyst has a high catalytic stability and may be used for a long time.

摘要： The present invention relates to the technical field of catalyst preparation, disclosing a preparation method and application of a coated vanadium-tungsten-titanium oxide monolithic SCR catalyst. The method includes the steps of mixing a vanadium oxide precursor, a tungsten oxide precursor, titanium dioxide, an inorganic adhesive, an organic adhesive and a macromolecular surfactant with deionized water and stirring them to obtain a thick liquid; adding a pH adjuster to the thick liquid to make its pH 1.5-4.5; impregnating a cordierite honeycomb carrier in the thick liquid to obtain a preliminarily-impregnated catalyst and dried and calcined the preliminarily-impregnated catalyst to obtain a finished catalyst. The method has advantages such as simple operation, easy repetition and short time-consuming, so it can be applied to exhaust gas post-treatment of a marine diesel engine, and provide a good choice for catalysts used to denitrify medium and high temperature exhausted gas from marine engines.
