Oxidation process for a gaseous phase oxidizable charge and the reactor for carrying it out.

摘要

The process comprises the following stages: a) an oxidisable feedstock (5) and an oxidising gas (6) are introduced into a dispersing zone (2) entirely filled with particulate elements of ceramic matter whose dimensions are such that the free spaces between the said elements have, at least in one direction, a dimension not exceeding the quenching distance of the flame capable of resulting from the oxidation of the said feedstock by the said oxidising gas, the said feedstock and the said oxidising gas being introduced into the said dispersing zone with the aid of at least one means of accelerating (7) the gases, embedded in the said particulate elements, enabling a gas velocity of at least 10 m s<-><1> to be obtained at the exit of the said accelerating means, and b) the gaseous mixture originating from stage (a) is reacted in a reaction zone (4) of ceramic material comprising a multiplicity of spaces (9) exhibiting passages which have, in at least one direction, a dimension not exceeding the said flame quenching distance, the interzone distance not exceeding the said flame quenching distance.
