Abstract
A process for reducing the aldehyde concentration in a target stream of a carbonylation process is disclosed. More specifically, a process for reducing the aldehyde concentration in an internal process stream or feed stream of a carbonylation process is disclosed. In particular, a process in which a target stream comprising a carbonylatable reactant and a first aldehyde concentration is subjected to a reaction comprising a supported catalyst that comprises at least one Group 8 to Group 11 metal at conditions sufficient to reduce the first aldehyde concentration to a second aldehyde concentration is disclosed.
Claims46
A process comprising:
- contacting a gas phase target stream that comprises a carbonylatable reactant and a first aldehyde concentration with a supported catalyst that comprises at least one Group 8 to Group 11 metal at conditions sufficient to reduce the first aldehyde concentration to a second aldehyde concentration.
A process comprising:
- contacting a target stream of a carbonylation process comprising a first aldehyde concentration in the gas phase with a supported catalyst comprising at least one Group 8 to Group 11 metal within a reaction vessel at conditions sufficient to produce a treated stream having a second aldehyde concentration that is less than the first aldehyde concentration;
- and removing the treated stream from the reaction vessel.
A process comprising:
- providing a gas phase feed stream of a carbonylation process comprising a carbonylatable reactant and a first aldehyde concentration to a reaction vessel containing a supported catalyst comprising at least one Group 8 to Group 11 metal;
- contacting the gas phase feed stream with the supported catalyst within the reaction vessel at conditions sufficient to produce a treated stream comprising a second aldehyde concentration that is less than the first aldehyde concentration;
- and removing the treated stream from the reaction vessel.
