TL;DR: In this paper, a method of removing a nitrogen oxide from an exhaust containing the same which comprises preparing an absorbent solution by adding divalent copper ions alone or a mixture of the divalent Copper ions and divalent manganese ions to an acid aqueous solution containing sulfites or acid sulfites of ammonium, alkaline metals, or alkaline earth metals or mixture of two or more of these compounds.

TL;DR: In this paper, a method for reducing NOx gas contained in an exhaust gas to harmless N2 gas with NH3 gas using an iron oxide catalyst was proposed, characterized in that said IRO catalyst comprises a substance consisting essentially of hematite crystals ( alpha -Fe2O3), and the peak intensity of X-rays diffracted on the (110) plane of the lattice of said crystal has a ratio of 0.6 to about 1.0.

TL;DR: In this paper, a method of removing nitrogen oxides from an exhaust which comprises the steps of contacting an exhaust containing nitrogen oxide and ammonia with a reducing catalyst received in a reactor to reduce the nitrogen oxide to nitrogen gas, wherein iron ore catalyst lumps having a particle size of 25 mm or less and forming a catalyst bed in the reactor are used as reducing catalyst, the lumps of the catalyst bed are let to fall gravitationally through the reactor continuously or intermittently.

TL;DR: In this article, a process for passing reaction gas with which the leakage of the reaction gas and the outer atmosphere at the charging inlet and the discharging outlet of reaction equipment containing the catalyst, can be prevented is described.

TL;DR: In this article, a solid-gas contact apparatus wherein a heat exchanger or catalytic reactor sectioned into a plurarity of chambers is inclined and so installed to be rotated freely thereby preventing occurence of troubles such as gas clogging and corrosion is presented.
