Effects of dilute acid pretreatment on chemical and physical properties of kenaf biomass

In the current research, kenaf represents an agricultural biomass that possesses enormous potential for industrial applications. Because of its complex structure, which is composed of cellulose, hemicellulose, and lignin, pretreatment process was conducted. Here, dilute acid pretreatment process w...

Because of its complex structure, which is composed of cellulose, hemicellulose, and lignin, pretreatment process was conducted.
