Abstract: An apparatus including a carbonizing furnace for obtaining a carbonized biomass by carbonizing a molded biomass and classification means disposed at the downstream side of the carbonizing furnace for classifying the carbonized biomass, and cooling means disposed at the downstream side of the classification means for cooling the classified carbonized biomass. The molded biomass is obtained by molding pulverized raw biomass and the cooling means cools the carbonized biomass by spraying water.

Abstract: A gas absorption tower comprising a primary desulfurization absorption section and a secondary desulfurization section are mounted in lower and higher portions, respectively, of the inside of the tower body. The primary absorption section mounted in the lower portion comprises an inner cylinder disposed substantially in the center of the tower body, a gas passage formed between the inner cylinder and the inner wall surface of the tower body, a gas introduction port opening into the gas passage, a gas inlet port formed in the side wall of the inner cylinder and opening into the cylinder, and a plurality of absorbent-spraying nozzles mounted along the flow of gas in the gas passage extending to the gas inlet port in the inner cylinder. The top of the inner cylinder is in communication with the secondary absorption section. The inner cylinder has a closed lower portion to form a vessel for holding absorbent dropping from the secondary absorption section.
