Abstract

A concentrated acid treatment unit is composed of a reaction section and an agitation extraction section. A phenol sorped raw material obtained by defatting botanical resource-derived raw material by solvent to subject sorption phenols to sorption is introduced, thus obtaining mixed solution of phenol solution including a lignophenol derivative and concentrated acid solution including a cellulose hydrolysate. The reaction section agitates and mixes the phenol sorped raw material and concentrated acid to cause cellulose to be swollen to thereby convert lignin to lignophenol. A part of the cellulose is subjected to hydrolysis. The agitation extraction section receives the treated liquid sent from the reaction section and adds phenols for extraction thereto to cause lignophenol dispersed in the concentrated acid solution to be dissolved and extracted in phenols for extraction.

Description

technical field [0001] The present invention relates to a plant resource phase separation system conversion device and conversion method capable of separating and recycling plant resources as lignocellulosic composite materials into sugars and lignophenol derivatives, and the conversion device and conversion method. Concentrated acid treatment part and concentrated acid treatment method. Background technique [0002] In order to effectively use plant resources as industrial raw materials to replace petroleum, it is necessary to fully utilize plant resources as molecular raw materials. For each component of a plant that is highly compounded at the molecular level, it is necessary to fully utilize the molecular functions. It is important to efficiently separate the constituents in this state. [0003] For example, wood is a complex of carbohydrates and lignin, which have completely different structures and properties. As methods for separating wood into two components, carbo...
