LIGNOCELLULOSIC BIOMASS SACCHARIFICATION PRE-TREATMENT DEVICE
First Claim
1. A lignocellulosic biomass saccharification pre-treatment device comprising:
- a mixing unit which mixes lignocellulosic biomass and ammonia,a heating unit which heats a biomass-ammonia mixture obtained by the mixinga separation unit which separates ammonia gas from the biomass-ammonia mixture heated by the heating unit to obtain a biomass-water mixture, anda transfer unit which transfers the biomass-water mixture separated by the separation unit to a later process,wherein the device comprisesan ammonia water supply unit which supplies ammonia water to the mixing unit,an ammonia recovery unit which recovers ammonia gas separated by the separation unit as ammonia water by dissolving the ammonia gas in water,a heat-of-dissolution recovery unit which recovers heat-of dissolution generated when ammonia gas is dissolved in water by the ammonia recovery unit, anda heat pump unit which generates heat to be supplied to the heating unit by using at least the heat-of-dissolution recovered by the heat-of-dissolution recovery unit as a heat source.

Abstract
A lignocellulosic biomass saccharification pre-treatment device is provided, which is capable of easily recovering ammonia water to be used in a pre-treatment for saccharification of a lignocellulosic biomass and putting in recycle use. The lignocellulosic biomass saccharification pre-treatment device has a mixing unit 2 for mixing lignocellulosic biomass and ammonia, a heating unit 3 for heating the biomass-ammonia mixture, a separation unit 4 for separating ammonia gas from the biomass-ammonia mixture to obtain a biomass-water mixture, and a transfer unit 6 for transferring the biomass-water mixture to a later process 5. The device has ammonia water supply unit 8 for supplying ammonia water to the mixing means 2, ammonia recovery unit 20 for recovering ammonia gas as ammonia water, heat-of-dissolution recovery unit 24 for recovering heat-of dissolution generated when ammonia gas is dissolved in water, and heat pump unit 30 for generating heat to be supplied to the heating unit 3 using at least the heat-of-dissolution as a heat source.
