Biomass hydrolysis with phosphotungstic acid

In this study, the effect of phosphotungstic acid on the biomass hydrolysis was investigated. Hydrolysis experiments were carried out in four different concentration ranges (1–4%) and at two different temperatures (200 and 250 °C) in the batch reactor. Biomass hydrolysis was investigated by determin...

Description
Summary:In this study, the effect of phosphotungstic acid on the biomass hydrolysis was investigated. Hydrolysis experiments were carried out in four different concentration ranges (1–4%) and at two different temperatures (200 and 250 °C) in the batch reactor. Biomass hydrolysis was investigated by determining the total organic carbon content and polysaccharides average molecular weights of hydrolysates. The hydrolysis efficiency and total organic carbon content increased with increasing phosphotungstic acid percentage, while polysaccharides average molecular weights were decreased at 200 °C. Increase of temperature in the presence of solid acid catalyst caused a significant increase on the biomass hydrolysis percentage. [Display omitted] •The effect of phosphotungstic acid on the biomass hydrolysis was investigated.•The highest solubility was achieved at using 3% PTA on biomass hydrolysis.•The average molecular weights of polysaccharides decreased as acidity increased.•Monosaccharide distribution differs with increasing acid concentration.•The temperature was more effective on hydrolysis than acid concentration.
