The invention relates to a method of producing carbonyl compounds, more particularly C-Cketones and aldehydes. The method is based on the gas-phase oxidation by nitrous oxide of C-Calkane-olefin mixtures, such as a butane-butylene fraction or a propane-propylene fraction, obtained by thermal and/or catalytic cracking, to produce C-Cketones and aldehydes. The process is carried out under continuous flow conditions at a temperature of 300-550&#xb0; C. and pressure of 1-100 atm, without prior isolation of individual olefins from the fractionation products and in the absence of a catalyst. The process provides for high productivity, high overall selectivity for ketones and aldehydes, and explosion-safe operation.

The present invention relates to a process for the purification of off-gases containing nitrogen oxides. An off-gas is passed through a reactor in admixture with ammonia or an ammonia precursor over a plurality of spaced catalyst beds under conditions to reduce the nitrogen oxides to nitrogen gas while heat is liberated. After the gas stream has obtained a desired temperature, the gas flow is reversed.
