Abstract
An oxidation reactor having elongated shape includes in combination, a mixing member including a pipe for feeding oxidizing gas and a pipe for feeding oxidizable charge; a reaction member, arranged subjacent the mixing member, and a discharge member associated with a discharge pipe for the products of the reaction. The reaction member includes a central zone which has a first lining and the reactor includes at least one peripheral zone which has a second lining, passages in the second lining being smaller than passages in the first lining so that the pressure loss in the second lining is greater than that of the first lining. The second lining forms a sleeve surround the first lining and this sleeve is formed of at least one refractory heat insulating material. The oxidation reactor is provided with an external sleeve steel jacket, a concrete wall and a steel element surrounding the mixing member arranged above the reaction member. The reaction member includes a series of single elements which form juxtaposed channels.
