<p>The reactor 1 that allows continuous regeneration of catalyst consists of a chamber 2 that comprises an oxychlorination zone superposed on a calcination zone equipped with a pipe for introducing calcination gas and a pipe for injecting oxychlorination gas 73. A mixing box is arranged between the oxychlorination zone and the calcination zone, at least one space 85 for catalyst grains to pass being made between the box and the chamber 2, with the mixing box comprising an inner space 80 surrounded by a gas-tight side wall 84, a gas-permeable bottom 83, and a roof 81 that covers the inner space 80. The pipe 73 for introducing oxychlorination gas empties into the inner space 80. The mixing box comprises means 82 for evacuating gas, whereby these means are arranged between said vertical wall 84 and the roof 81.</p> |
