Claims
- 1. A method for forming formaldehyde from methanol and oxygen comprising:contacting a reactant stream containing methanol and oxygen at methanol conversion conditions with a fixed bed of particulate solids comprising a particulate source of iron oxide and a second particulate source of molybdenum oxide to form a catalyst composition and to convert said methanol into formaldehyde, wherein said first particulate source of iron oxide is different from said second particulate source of molybdenum oxide.
- 2. A method according to claim 1 wherein said methanol conversion conditions comprise a temperature within the range from about 150°-500° C.
- 3. A method according to claim 1 wherein said particulate source of iron oxide comprises powdered ferric oxide.
- 4. A method according to claim 1 wherein said particulate source of molybdenum oxide comprises molybdenum trioxide.
- 5. A method according to claim 1 wherein said reactant stream further contains an inert gas.
- 6. A method for forming formaldehyde from methanol and oxygen comprising: contacting a reactant stream containing methanol and oxygen at methanol conversion conditions with a fixed bed of particulate solids comprising a first particulate source of a metal oxide and a second particulate source of molybdenum oxide to form a catalyst composition and to convert said methanol to formaldehyde, wherein said first particulate source of metal oxide is different from said second particulate source of molybdenum oxide.
- 7. A method according to claim 6 wherein said first particulate source of metal oxide is selected from oxides of iron, lead, cadmium, zinc, bismuth, sodium, manganese, gadolinium, magnesium, copper, cobalt, tellurium, aluminum, chromium, nickel, and combinations thereof.
- 8. A method according to claim 6 wherein said methanol conversion conditions comprise a temperature within the range from about 150°-500° C.
- 9. A method according to claim 7 wherein said particulate source of metal oxide comprises powdered ferric oxide.
- 10. A method according to claim 6 wherein said particulate source of molybdenum oxide comprises molybdenum trioxide.
- 11. A method according to claim 6 wherein said reactant stream further contains an inert gas.
