“…These three chemicals are the main by-products in the spent liquor. Their production can be modeled as(Aguilar et al, 2002;Gámez et al, 2006;Rueda et al, 2015;Yan et al, 2014):(5)Where: C D = Concentrations of HMF, furfural, and acetic acid, g L -1 C 0 = Regression parameters, potential concentrations, g L -1 k 3 = Rate constants of reactions, min -1 Once the rate constant of reaction (k i ) is determined, the other important kinetic parameters can be correlated with temperature using the Arrhenius Equation(Gámez et al, 2006):…”

The aim of this work was to investigate the kinetics of multiple chemicals in acid bisulfite pretreatment and the relationship between total sugar yields and pretreatment factors (temperature and time). The results showed Saeman model accurately fitted the pretreatment process. According to this kinetic model, a maximum hemicellulose hydrolysis yield was achieved at a treatment time of 75min with a temperature of 145°C. Meantime, the concentrations of acetic acid, hydroxymethylfurfural (HMF), and furfural were 1.54, 0.60, and 1.15gL, respectively. Also, a Lorentzian function described the relationship between total sugar yield and pretreatment factors: temperature and time. The regression parameters from this mathematical fitting have accurately reflected the maximum total sugar yield and the optimal treatment conditions were determined to be 145°C and 110min.
