Patent ID: 8460515

Claim:
A process for producing biocokes using pulverized biomass raw material attributed to photosynthesis, by heating and pressure molding, in reaction vessels, the pulverized biomass of which the moisture content is regulated to a given ratio, wherein a plurality of said reaction vessels and a pulverizate delivery path for delivering the pulverized biomass are provided, each of the reaction vessels being connected to the pulverization delivery path via connection tubes, wherein a temperature range and a pressure range for inducing a pyrolytic of hemicellulose and thermal curing reaction of lignin thereof are preset, said process comprising: maintaining the pulverized biomass in each of the reaction vessels for a predetermined period of time in a pressurization state and a heating state while in the pressure and temperature range; cooling the pulverized biomass; treating the pulverized biomass in a series of treatments for discharging produced biocokes from a bottom of the reaction vessels; and charging a predetermined amount of the pulverized biomass from the pulverizate delivery path via the connection tubes to a corresponding one of the reaction vessels in accordance with a timing of pulverizate charging to the reaction vessels in said treating by opening and closing gates in the connection tubes.
