Research on Biomass Corn Stalk of Catalytic Liquefaction Process by Response Surface Methodology
In order to get high yield of biomass liquefaction oil,using corn straw as raw material,liquefied duration(LD),liquefaction temperature(LT) and catalyst dosage(CD) as influence factors for design Box-behnken experiment,the quantitative mathematical model of experimental factors and interaction of between factors effect on the liquefaction of corn stalk rate were got,response surface method(RSM) was used to determine the optimum process eonditions.The result shows that it was highly significant(P＜0.000 1)that the quadratic regression mathematics model established according to experimental data,which the coefficient of correlation is R2=0.953 8.The degree of fitting is provided with between the predicted value and the experimental value.When the LD is 63.66 min,the LT is 162.43 ℃ and the CD is 4.02％ for the best catalytic liquefaction conditions;Under the condition of the process,the liquefaction rate of corn straw is 98.88％,while the predictive value is 98.87％,which the relative deviation between them is 0.01％;Therefore,it is concluded that the optimization of the process parameters of corn stalk catalytic liquefaction by the RSM is more precise and reliable,and has a certain reference value.
