Hemicellulose solubilization and cellulose recovery after steam pretreatments performed at a constant severity of 3.6 with the addition of 0.7 wt% H2SO4 (on biomass) and temperatures increasing in 10 °C increments from 160 to 200 °C denoted, SP1–SP5 respectively. Sample SP2# was treated without the addition of the H2SO4 catalyst
