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