  • Publication number: 20120083611
    Abstract: A process is provided for producing furfural from solid biomass by gaseous acid catalysed hydrolysis and dehydration in the presence of superheated steam and one or more acid catalysts. The solid biomass is heated to a temperature which is sufficiently high to ensure that the superheated steam and the acid catalyst or catalysts to be used remain in gaseous form during the reaction. The heated solid biomass is contacted with a gaseous stream containing superheated steam and one or more acid catalysts to produce a furfural-containing gaseous stream containing superheated steam, one or more acid catalysts and furfural. The furfural-containing gaseous stream is recirculated to bring it into further contact with the heated solid biomass to enrich the concentration of furfural.
