Abstract
A process is provided for the synthesis of furan and related compounds by vapor phase decarbonylation of furfural and derivatives, using a palladium/alumina catalyst that has been promoted with an alkali carbonate. Catalyst lifetime is improved. The catalyst can be regenerated in situ by feeding a mixture of air and steam, with a composition of between about 2% and about 40% air, to the catalyst bed at a temperature between about 300° C. and about 500° C.
