Abstract: Proposed is a carbon dioxide reforming (CDR) reactor having a multilayered catalyst layer arrangement for preventing catalyst deactivation, wherein, in the reactor in which a CDR reaction for reacting methane (CH4) with carbon dioxide (CO2) to reform the methane into a synthesis gas including carbon monoxide (CO) and hydrogen (H2) is performed, in order to prevent a case where an endothermic reaction between a catalyst and heated reactant gas supplied to the reactor gradually causes the temperature of the reactant gas to decrease and the catalyst is deactivated by cokes generated due to the decrease in temperature of the reactant gas, CDR catalysts in the reactor are arranged in multiple layers in a multilayered structure to allow the reactant gas temperature that has decreased due to the endothermic reaction to be restored in spaces between the catalyst layers.

Abstract: The present invention relates to a low-concentration air pollutant selective detection device and, more specifically, to a low-concentration air pollutant selective detection device capable of detecting a low-concentration air pollutant with high sensitivity, and selectively detecting an air pollutant when necessary. The low-concentration air pollutant selective detection device of the present invention comprises: a sensor which is located in a flow path, through which the gas moves, to detect contaminants in the gas; and a concentrator part which, by including an adsorbent that is positioned in the flow path of the gas that moves to the sensor and adsorbs contaminants in the gas, and a desorption means that is positioned adjacent to the adsorbent to individually desorb different contaminants from the adsorbent, delivers the concentrated contaminants to the sensor.

Abstract: The present invention provides a solid-phase catalyst for decomposing hydrogen peroxide comprising a permanganate salt and a manganese (II) salt. The solid-phase catalyst stays a solid state in the form of nanoparticles at the time of hydrogen peroxide decomposition, and thus can be recovered for reuse and also has an excellent decomposition rate. In the method for producing a solid-phase catalyst for decomposing hydrogen peroxide according to the present invention, a solid-phase catalyst is produced from a solution containing a permanganate salt, a manganese (II) salt, and an organic acid, so that the produced solid-phase catalyst is precipitated as a solid component even after a catalytic reaction, and thus is reusable and environmentally friendly, and cost reduction can be achieved through the simplification of a catalyst production technique.
