Vast amounts of renewable biomass are available for conversion to liquid fuel, ethanol. In order to convert biomass to ethanol, the efficient utilization of both cellulose-derived and hemicellulose-derived carbohydrates is essential. Six-carbon sugars are readily utilized for this purpose. Pentoses, on the other hand, are more difficult to convert. Several metabolic factors limit the efficient utilization...
Ethyl levulinate (EL) has been identified as a versatile chemical feedstock derived from biomass. The production of EL from cellulose in the system containing alcohol was studied. In addition, the effects of water and organic solvent (cyclohexane) on EL yield were also investigated. The results show that higher acid concentration can improve the conversion of cellulose to EL and the addition of cyclohexane...
The alkali pretreatment and enzymatic hydrolysis of banana pseudostem (BPS) for the production of ethanol was optimized using response surface methodology. Alkali concentration, temperature and time were considered as independent variables and reducing sugars concentration was a response variable. Pretreatment of BPS was performed at different alkali concentration, temperature and pretreatment time...
