Abstract
The present invention provides a process for the production of furan, said process comprising the steps of: i) contacting furfural with a decarbonylation catalyst in a decarbonylation reactor to produce a gaseous decarbonylation reaction product stream comprising furan and carbon monoxide; ii) contacting said gaseous decarbonylation reaction product stream with a solvent stream comprising furfural; iii) absorbing at least a portion of the furan present in the gaseous decarbonylation reaction product stream into the solvent stream to provide a furan-containing solvent stream and a gaseous stream comprising carbon monoxide; iv) separating the furan from the furan containing solvent stream by distillation to provide a first furan stream; and v) using at least a portion of the remaining solvent stream comprising furfural as at least a portion of the furfural provided to the decarbonylation reactor.
