Abstract

A process is provided for the synthesis of furan and related compounds by vapor-phase decarbonylation of furfural and derivatives, using a palladium/metal aluminate catalyst that has been promoted with an alkali carbonate, such as cesium carbonate. The use of such catalysts, which are inherently less acidic than alumina, results in improved lifetime and high productivity.
