摘要： A method of manufacturing a methane oxidation catalyst and methane oxidation catalysts formed by the method are provided. The method includes providing a palladium (Pd)-based catalyst including Pd dispersed onto a support. A magnesium (Mg) precursor is introduced to the Pd-based catalyst by one of ion exchange or incipient wetness impregnation. After introducing the magnesium precursor to the Pd-based catalyst, the catalyst is dried and subjected to a final heat treatment that includes hydrothermal calcination. A method of methane oxidation in a lean exhaust environment via the methane oxidation catalyst is also provided.

摘要： The present disclosure relates to a method for generating a hydrogel from a CO2 gas stream. The method for converting a CO2 gas stream comprising a CO2 into an ester, comprises the conversion of CO2 into a (COOH)2 preferably by passing the CO2 through a water bath to produce a carbonated water; and passing the carbonated water through a metal ion exchange bubble column comprising a M2(COO)2 to produce the (COOH)2 and a MHCO3; reacting the (COOH)2 with a mono-alcohol to obtain the ester. The invention further relates to a system for converting CO2.

摘要： An exhaust gas-purifying catalyst includes a catalyst-coated filter and inorganic particles in a powder form. The catalyst-coated filter includes a filter substrate and a catalyst layer on a pore wall of the filter substrate. The catalyst-coated filter has a first end portion, a second end portion, a filter wall, an entry-side cell, and an exit-side cell. The filter wall is porous. The entry-side cell is opened at the first end portion and closed at the second end portion. The exit-side cell is opened at the second end portion and closed at the first end portion. The entry-side cell and the exit-side cell are adjacent to each other with the filter wall interposed therebetween. The inorganic particles in a powder form are localized at a surface of the filter wall adjacent to the entry-side cell at a cross section parallel to the thickness direction of the filter wall.
