Levulinic acid production from wheat straw
Abstract
Studies were carried out on the effects of temperature, acid concentration, liquid:solid ratio and reaction time on levulinic acid production from wheat straw using response surface methodology. The P-value of the coefficient for acid concentration was 0.0002, suggesting that this was highly significant. The quadratic effects of temperature and liquid:solid ratio were also significant and their P-values were <0.0001 and 0.0027, respectively. The coefficient determination (R 2) was good for the second-order model. The optimal conditions for levulinic acid production from wheat straw were 209.3 °C, 3.5% acid concentration, 15.6 liquid:solid ratio and 37.6 min of reaction time resulted 19.86% yield.
