Abstract
This invention relates to the production of formaldehyde and to catalysts which may be used therefore. In more detail the invention relates to a process for the production of formaldehyde from methanol includes the passage, at an elevated temperature, of a gas stream containing methanol and oxygen through a catalyst, the catalyst comprising a monolithic support provided with channels for passage therethrough of the gas stream and with the channel wall surfaces coated or impregnated with one or more elements selected from the group consisting of copper, silver, gold and iron.
Claims6
A process for the production of formaldehyde from methanol includes the passage, at an elevated temperature, of a gas stream containing methanol and oxygen through a catalyst, the catalyst comprising a monolithic support provided with channels for passage therethrough of the gas stream and with the channel wall surfaces coated or impregnated with at least one member of the group consisting of copper, silver, gold and iron.
In a process for the production of formaldehyde from methanol which comprises passing at an elevated temperature sufficient to convert the methanol to formaldehyde by oxidative dehydrogenation the modification which comprises using, as the catalyst, one comprising a monolithic support provided with channels for passage therethrough of the gas stream the channel wall surfaces being coated or impregnated with at least one member of the group consisting of copper, silver, gold and iron.
