Abstract
Abstract Fermentation–pervaporation–catalysis (FPC) integration process was employed to produce bio-butadiene using sweet sorghum juice as feedstock. After in situ ethanol removal from fermentation broth, permeate of pervaporation membrane (478.6 g/L bio-ethanol) was directly converted into butadiene by an Ag/Mg–Si catalyst. A butadiene yield of 64.1% with a butadiene selectivity of 75.8% was achieved within 6 h of operation. The integration process showed a great potential on high final product yield in a long-term operation. Following this protocol, about 16 g of bio-butadiene was produced from 1 kg sweet sorghum stalk. The integration process showed a potential in further application for bio-butadiene and materials production.
