Abstract:
In this study, a novel process concept is presented based on formic acid catalysed conversion of hemicellulose and cellulose. Lignin-free xylose-cellulose mixture is used as a model feedstock in order to investigate the appropriate reaction conditions to produce furfural from hemicellulose and glucose from cellulose. The first stage in this concept is for furfural production and the second one for glucose production. Separation of unreacted cellulose and soluble components can be done by washing and filtration. The study showed that both furfural and glucose can be produced in the simple reactor system. By combining appropriate temperature, acid concentration and time, furfural production can be optimised while minimising cellulose hydrolysis in the first reactor. This requires milder conditions in the first reactor than in the second one. Moreover, the possible separation units were considered in the study.
