LIGNOCELLULOSIC BIOMASS SACCHARIFICATION PRE-TREATMENT DEVICE
First Claim
1. A lignocellulosic biomass saccharification pre-treatment device comprisinga mixing unit configured to obtain a substrate mixture by mixing lignocellulosic biomass serving as a substrate and ammonia water;
- a reservoir unit configured to obtain a pretreated material for saccharification in which lignin is dissociated from the substrate or the substrate is swollen by storing the substrate mixture obtained by the mixing unit; and
a separation unit configured to separate ammonia gas continuously from the pretreated material for saccharification by heating the pretreated material for saccharification supplied from the reservoir unit, wherein the device comprisesan ammonia recovery unit configured to recover the ammonia gas as ammonia water by dissolving the ammonia gas separated in the separation unit in water;
a first heat recovery unit configured to recover heat-of-dissolution generated when ammonia gas is dissolved in water in the ammonia recovery unit; and
a heat supply unit configured to generate heat to be supplied to the separation unit by using the heat-of-dissolution recovered by the first heat recovery unit as a heat source and to supply the heat to the separation unit.

Abstract
Provided a lignocellulosic biomass saccharification pre-treatment device capable of producing a pretreated material for saccharification.
The lignocellulosic biomass saccharification pre-treatment device comprises a separation unit 4 which separates ammonia gas by heating a pretreated material for saccharification obtained from a substrate mixture obtained by mixing lignocellulosic biomass and ammonia water; a first heat recovery unit 25 which recovers heat-of-dissolution generated when ammonia gas is dissolved in water, and the heat supply units 8, 9, 10 which generate heat by using heat-of-dissolution recovered by the first heat recovery unit 25 and supply the heat to the separation unit 4.
