Abstract:
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, and a transfer unit which transfers the biomass-water mixture separated by the separation unit to a later process, wherein the device comprises an 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, and a 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.
