Abstract
Methods comprising: (a) providing a starting mixture comprising at least one hydrocarbon and at least one oxygen source, wherein the starting mixture has a fuel number of at least 4; (b) heating the starting mixture to a temperature of not more than 1400° C. and subjecting it to a single-stage, autothermal, uncatalyzed reaction to form a reaction gas; and (c) subjecting the reaction gas to rapid cooling to form at least one olefin and synthesis gas are described.
