BIOCOKES PRODUCING METHOD AND APPARATUS

摘要

It is intended to provide biocokes producing method and apparatus which can produce biocokes efficiently and in a short amount of time. A method of producing biocokes in which pulverized biomass is fed and pressed in a reaction container, the pulverized biomass in a substantially-packed state is pressure-formed while being heated in a temperature range and a pressure range to obtain a semi-carbonized solid matter or pre-semi-carbonized solid matter and then cooled to produce biocoke. The method may include, but is not limited to: a filling step having the substeps of: feeding the pulverized biomass to the reaction container, and then pressing the pulverized biomass in the reaction container by lowering a pressurizing member from above the reaction container at a pressure lower than the pressure range; a reaction step having the substeps of: pressurizing the pulverized biomass in the pressure range by increasing a pressure of the pressurizing member to the pressure range; heating the pulverized biomass by means of a heating device to the temperature range and keeping such state for a prescribed period of time to form a shaped matter of the pulverized biomass in the reaction container, and then cooling the shaped matter by switching from the heating device to a cooling device; and an ejecting step having the substeps of: reducing the pressure of the pressurizing member, and then releasing the bottom part of the reaction container to eject the shaped matter having been cooled.
