Abstract:
1. A method comprising reacting an initial stream comprising one or more hydrocarbons with an oxygen-containing gas stream, to form a product stream, wherein: the oxygen-containing gas stream has a predetermined oxygen concentration and a predetermined temperature; the oxygen-containing gas stream is obtained by combusting a fluid fuel stream with a primary air stream, such that λ values of the primary air stream to the fluid fuel stream range from 0.6 to 1.2, to obtain a combustion gas stream, and then admixing secondary air stream with the combustion gas stream to obtain the oxygen-containing gas stream; the predetermined oxygen concentration of the oxygen-containing gas stream ranges from 2 to 20 vol. % and the predetermined temperature of the oxygen-containing gas stream is adjusted via flow rate and temperature of the secondary air stream; and the combusting and the admixing occur within a combustion chamber comprising
