A common problem in autothermal reformers is the evolution of the axial temperature profiles, which can exhibit pronounced hot-spots near the reactor inlet. These high temperatures introduce considerable stress on the reactor materials and can damage the catalyst. An attractive alternative to lower the hot-spots is to distribute the oxygen feed along the reactor length. This controlled feed of oxygen can be achieved by using a multibed configuration with lateral feed of O2 and also by means of a multitubular membrane reactor with O2 distribution through the porous wall. This work explores four different options of O2 feeding for ATR.
