The oxidation of methane on POB>4-deficient barium hydroxyapatite (BaHAp) has beeninvestigated in the presence and absence of tetrachloromethane (TCM). In the absence of TCM,the principal product was CO₂ with less than 20% selectivity to partial oxidation and oxidative-coupling products. On introduction of a small partial pressure of TCM to the feedstream andwith higher times-on-stream, the formation of CO₂ was virtually eliminated while CO and theC₂ hydrocarbon became the dominant products. The observations with TCM can be attributed tothe chlorination of the catalyst and, in particular, the formation of the corresponding chlorapatite.
