Abstract: The present invention provides a process for removing mercaptans from a gas stream. A first mercaptan-comprising gas stream is contacted counter-currently with an absorption medium comprising a substituted disulphide and a nitrogen-containing base to obtain a second mercaptan-depleted gas stream. The substituted disulphinde preferably is RII—SS—RIII wherein: RII and RIII are the same and are selected from: —(CH2)n-X, wherein n=2 or 3, and wherein X=OR, and wherein R=H or —(CH2O)nH or —(CH2O)nCH3 and n=1 or 2. Absorption medium is regenerated and recycled.

Abstract: The present invention provides a process for the treatment of a liquid first furan stream comprising furan and carbon monoxide, said process comprising the steps of: i) contacting said first furan stream with a CO-lean first gaseous stream; and ii) stripping at least a portion of the carbon monoxide in the first furan stream into the first gaseous stream to produce a second furan stream comprising less carbon monoxide than the first furan stream and a CO-enriched second gaseous stream.

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.
