Two stage butane haleic anhydride process |
摘要 |
Butane is oxidized with molecular oxygen in a dilute state by bringing a mixture of vaporized butane and air of controlled butane content into the presence of a contact vanadium-phosphorus-oxygen catalyst in a first oxidation zone under controlled pressure and temperature conditions, cooling the gaseous effluent from the first oxidation zone to a temperature in the range of 50 DEG to 300 DEG C., introducing a controlled amount of butane into the cooled gaseous effluent from the first oxidation zone, introducing said cooled butane-enriched stream into the second oxidation zone, and bringing the thus butane-enriched mixture into contact with a vanadium-phosphorus-oxygen catalyst disposed in the second zone.
