BIOCOKE PRODUCING APPARATUS, METHOD OF CONTROLLING THE SAME AND PROCESS FOR PRODUCTION THEREOF

摘要

A biocoke producing apparatus that realizes efficient mass production of biocoke; a method of controlling the same; and a process for manufacture thereof. The apparatus includes a horizontal tubular reaction vessel (10) provided on its one end side with a supply part (11) for pulverized biomass and provided on its other end side with a discharge part (12). On the supply part side, there is provided an extrusion piston (6) capable of reciprocation along the longitudinal direction in the interior of the reaction vessel and capable of pressurizing the pulverized biomass within the vessel; The temperature range and pressure range for inducing a pyrolytic or thermal curing reaction of lignin and hemicellulose contained in the pulverized biomass are preset, and the reaction vessel (10) is provided with a thermal reaction region (13) for heating the pulverized biomass at temperature within the above temperature range and with a cooling region (14). By means of the extrusion piston (6), not only is the pulverized biomass transferred so as to stay for a given period of time in each of the regions but also the pulverized biomass within the vessel is pressurized so as to fall within the above pressure range.
