    摘要: Hydroxylammonium salts are eliminated from wastewaters containing such salts by a process which comprises treating a wastewater containing such salts with not less than 0.5 mole of manganese (IV) oxides per mole of hydroxylamine in the form of hydroxylammonium salts at a pH of from 1 to 4 and at from 10.degree. to 100.degree. C.

    摘要: Recuperative heat exchangers or regenerative heat exchangers are used for the thermal decomposition of N2O in N2O-containing gases. The process for the thermal decomposition of N2O in N2O-containing gases at from 800 to 1200° C. comprises passing the N2O-containing gas through one or more recuperative heat exchangers or regenerative heat exchangers in such a way that when the gas to be reacted is passed through a charge of heat transfer material it is heated to a temperature in the range from 800 to 1200° C. and the N2O present is decomposed thermally, and cooling the reacted gas by heat exchange so as to heat the charge of heat transfer material and the gas to be reacted.
