摘要:
A denitration process for removing nitrogen oxides contained in low-temperature exhaust gas at a high denitration rate; namely, a denitration process for reductively removing nitrogen oxides contained in an exhaust gas (x) containing nitrogen monoxide and sulfur dioxide. The process comprises a preliminary step 2 of partially oxidizing nitrogen monoxide in the exhaust gas to form nitrogen dioxide, a radical formation step 3 of adding a nitrogen compound and a hydrocarbon compound to a high-temperature zone 22 to form amine radicals (r), and a denitration step 4 of mixing the amine radicals (r) with the pretreated gas (p) containing nitrogen monoxide and nitrogen dioxide that was discharged from the preliminary step 2. As a result, nitrogen oxides in the exhaust gas (x) are reductively decomposed.

To produce a cell culture membrane having biocompatibility utilizing DNA of natural resources and a cell culture kit, the cell culture membrane having DNA ionically-cross-linked with calcium ions or magnesium ions is provided. To produce a porous material utilizing DNA, a production method for a cell culture membrane and a production method for a porous material, fine pores of 1 nm to 100 μm in diameter are prepared in the porous material.
摘要:
A method of exhaust gas denitration in which nitrogen oxides contained in a low-temperature exhaust gas are removed at a high NOx removal efficiency. A injection pipe (11) is disposed in a flue (10) for an exhaust gas (x) so that the pipe protrudes from the inner wall of the flue. A hydrocarbon compound (b) and a nitrogen compound (a) are supplied through the injection pipe (11) into the flue (10). The hydrocarbon compound (b) is burned to form a combustion region (s). In this combustion region (s), amine radicals are produced from the nitrogen compound (a). These amine radicals are mixed with nitrogen oxides contained in the exhaust gas (x) to reductively remove the nitrogen oxides.
