The partial oxidation of the feedstock is necessary to obtain the thermal energy required for the endothermic stages of the process in order to maintain the operative temperature at the required value. The oxidation phase is carried out in near oxygen free conditions in order to oxidize only part of the feedstock. The main reaction that take place during the oxidation phase are the following: | The partial oxidation of the feedstock is necessary to obtain the thermal energy required for the endothermic stages of the process in order to maintain the operative temperature at the required value.
