Title:
METHOD FOR ULTRA-LOW-TEMPERATURE CARBONIZATION TREATMENT OF BIOMASS MATERIAL, AND METHOD FOR PRODUCING CARBIDE
Document Type and Number:
WIPO Patent Application WO/2017/195407
Kind Code:
A1
Abstract:
[Problem] To provide: a novel carbonization treatment method for carbonizing a biomass material containing a large amount water at an extremely low temperature; and a method for producing a carbide. [Solution] A water-containing biomass material is carbonized while maintaining the biomass material under treatment conditions including an oxygen-containing atmosphere and a temperature range of 70ºC or higher and lower than 100ºC, without the need to subject the biomass material to a drying step for removing or reducing the water forcibly. In this process, it is preferred that the water content (in percent) in the biomass material at a time point at which the carbonization of the biomass material starts while maintaining the biomass material under the above-mentioned treatment conditions is 40 to 80% inclusive, and it is more preferred that the above-mentioned maintenance is carried out for two weeks or longer. As the biomass material, at least one biomass material selected from a waste-material-type biomass material, e.g., a food-derived waste material, a livestock excrement, an agricultural-product-derived waste material, a seafood-derived waste material and a forest-product-derived waste material, and a plant- (cultivated crop)-derived biomass material can be used.
