Abstract: The invention relates to a cellulose solution manufacturing method including: performing an ozonation treatment to bring a cellulose-containing material and ozone into contact with each other; and performing an alkali treatment to bring the obtained treated material and an alkali aqueous solution into contact with each other, thereby dissolving at least cellulose in the cellulose-containing material brought into contact with the ozone in the alkali aqueous solution. According to the invention, it is possible to provide a method of manufacturing a cellulose solution in which cellulose can be dissolved in a more simple manner, a method of manufacturing a cellulose precipitate in which cellulose can be recovered from the cellulose solution, and a method of saccharifying cellulose which uses the cellulose precipitate.

Abstract: A pillared structure of a gas-treating apparatus of a construction such that a plurality of chambers defined by partition members adjoin in a circular arrangement in the outer peripheral part of a rotary cage, each chamber being packed with an adsorbent, the cage being adapted to rotate, bringing the chambers by turns into at least an adsorption zone and then a desorption zone, characterized in that a plurality of hollow pillars for holding the partition members in place are rigidly joined at the lower ends to the upper surfaces of a plurality of rigid bottom beams radially extending from a central rotating shaft of the cage, and that holes are formed in the pillars for introducing a cooling fluid into the uprights.
