Block flow diagram for the production of petroleum refinery feedstocks from furfural in an integrated biorefinery. Furfural production from hemicellulose extract through dehydration is not shown. Key: FAF – furfural–acetone (2:1) dimer (i.e. the aldol condensation product of furfural and acetone), Oli – oligomeric adducts formed by Michael addition reactions, H-FAF – hydrogenated furfural–acetone (2:1) dimer, Cyc – cyclic compounds formed by hydrogenation and Diels–Alder reactions.
