Kinetics of Bamboo Fiber Hydrolysis Reaction in Saturated Formic Acid

摘要：

　　Kinetic models can have practical applications for the optimization of the process and performance analysis,or economic estimations,so investigate the bamboo fiber kinetics is necessary.In this paper,effects of temperature and time on bamboo fiber hydrolysis in saturated formic acid with 4% hydrochloric acid solution reaction kinetics have been investigated.The rate constants,average apparent activation energy and frequency factors were evaluated according to the Arrhenius equation.The results showed that the hydrolysis velocities of bamboo fiber were 1.63×10-2 h-1 at 55 ℃,2.59×10-2 h-1 at 60 ℃,4.56×10-2 h-1 at 65 ℃,6.75×10-2 h-1 at 70 ℃ and 0.10 h-1 at 75 ℃ in formic acid solution with 4 % hydrochloric acid.The degradation velocities of glucose were 6.57×10-3 h-1 at 55 ℃,1.98×10-2 h-1at 60 ℃,2.53×10-2 h-1 at 65 ℃,7.47×102 h-1 at 70 ℃ and 0.14 h-1 at 75 ℃.The pre-exponential factor of Arrhenius equation of bamboo fiber hydrolysis reaction and glucose decomposition was 1.48×1014 h-1 and 2.32×1020 h-1 respectively.The activation energy of bamboo fiber hydrolysis was 87.65kJ/mol,and the activation energy of glucose degradation was 141.44kJ/mol.
