Abstract

The invention relates to the conversion of saturated hydrocarbons. According to the invention a first gas containing chlorine and a second gas containing hydrogen are introduced into a chamber (3) so as to mix them. At the exit (4) of this chamber (3) the mixture of chlorine and hydrogen is ignited and the products originating from this flame are then mixed in a chamber (7) with a third gas containing the hydrocarbons to be converted, with a mean weight content of hydrogen element of at least 18%. The effluents from the chamber (7) are collected, quenched and fractionated. The hydrochloric acid is reformed into chlorine which is recycled in the first gas, the hydrogen is recycled in the second gas, and the alkanes in the third gas. The unsaturated hydrocarbons are recovered. The invention applies in particular to the conversion of natural gases into unsaturated hydrocarbons, such as ethylene.
