Pretreatment Process for Lignocellulose by Dilute Hydrochloric Acid

Pretreatment process for lignocellulose by dilute hydrochloric acid was performed and four factors including reaction temperature(θ),reaction time(t),concentration of hydrochloric acid(c),and the ratio of liquid/solid(r) were studied by method of Plackett-Burman design.Finally,the preferred pretreatment conditions are found as follows: t=1 h,θ=115 ℃,c=1% and r=10.
