Abstract

The invention belongs to the technical field of lignocellulose pretreatment, in particular to an FeOCl-based lignocellulose pretreatment system and application thereof. The pretreatment system consists of the following effective components including 0.2-3.5 g / L of FeOCl and 0.09-1.55 mol / L of peralcohol, wherein, the peralcohol is any one of hydrogen peroxide and sodium peroxide or a mixture of the hydrogen peroxide and the sodium peroxide in an arbitrary proportion; and the pH value of the pretreatment system is 3-8. The pretreatment system can have a Fenton-like catalytic reaction within thepH value range of 3-8; the treatment time is short; and the degradation efficiency of lignin and cellulose in a lignocellulose raw material is effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of lignocellulose pretreatment, and in particular relates to a FeOCl-based lignocellulose pretreatment system and its application. Background technique

[0002] Lignocellulose is an extremely abundant renewable resource, which is widely distributed all over the world. In order to solve the current global energy crisis, the rational use of biomass resources is particularly important. Due to its complex and compact structure, lignocellulose in nature poses great challenges to the conversion and utilization of biomass resources. Pretreatment of lignocellulose by chemical, physicochemical or biological methods can overcome its recalcitrant structure and increase the carbon and water content. Compound enzymatic conversion efficiency. The existing physical and chemical pretreatment methods often involve harsh conditions such as high temperature, high pressure, strong acid and strong alkali, which often cause a la...
