✦ Synopsis

The oxidative conversion of methane by O 2 to CO and H 2 (i.e. syngas) over NiO supported on microporous aluminophosphate (ALPO-5) in the presence or absence of simultaneously occurring CO 2 and steam reforming reactions of methane has been investigated. During the catalytic reactions, the NiO/ALPO-5 is transformed into Ni0/AlPO 4 (tridymite). The catalyst shows high activity and selectivity, particularly at high temperatures (>1073 K ), in the oxidative conversion of methane to syngas and also in the exothermic oxidative conversion that occurs simultaneously with the endothermic CO 2 and steam reforming of methane. In the latter case, the overall catalytic process can be made almost thermoneutral, requiring little or no external energy. The process also occurs in a most energy efficient and safe manner.
