(54) Title: PROCESS FOR THE CONVERSION OF METHANE INTO PROPANAL 7 r (57) : The present invention provides methods for making propanal in a reaction comprising the oxidative coupling of methane © (OCM) and oxygen as a reactant stream in a gas phase reaction, preferably in the presence of water or steam, to form ethylene, ethane, In carbon dioxide (CO2), water and syngas (CO and H2) in a first reactor as an ethylene stream, and then forming propanal in a second reactor by feeding to the second reactor the ethylene stream with the syngas from the first reactor in the gas phase and hydroformylating 0 ---- in the presence of a catalyst for a water shift reaction. In the method, the ratio of H2 to CO in the syngas is maintained by either co- GC , 1 feeding steam into the first reactor or the second reactor to generate additional H2 in the syngas, or by forming CO in the second reactor 0 from the water shift reaction by feeding the CO2 from the ethylene stream into the second reactor. ei O
