Method and apparatus for pretreating biomass using internal heat

摘要

A method for pretreating a biomass, in which a water-reactive anhydride contacts a biomass, is disclosed. The biomass is pretreated using internal heating by an exothermic reaction. Further, an apparatus for pretreating a biomass having a reaction part including an inlet part and an outlet part for the water-reactive anhydride is disclosed.

主权项

1. An apparatus for pretreating a biomass, comprising:
a reaction part for pretreating a biomass, the reaction part including an inlet part which is formed at a first end of the reaction part and through which a gaseous water-reactive anhydride can be input, wherein the inlet part is connected to a first supply tank containing fresh gaseous water-reactive anhydride, and an outlet part which is formed at a second end of the reaction part opposite the first end and through which the gaseous water-reactive anhydride can be output; a biomass supply part for supplying a biomass to the second end of the reaction part; a water supply part formed between the biomass supply part and the reaction part, and connected to the second end of the reaction part to supply water to the biomass; a washing part connected to the first end of the reaction part to wash the biomass, and a separation part connected to the washing part for separating components extracted from the biomass, wherein the inlet, outlet, and biomass supply parts are configured such that the direction of flow of the gaseous water-reactive anhydride through the reaction part is the reverse of the direction of transfer of the biomass through the reaction part.
