Abstract
An apparatus and process for producing biocoke usable as a substitute fuel for coal coke from biomass as a raw material. The apparatus comprises pulverizing means for pulverizing a biomass raw material attributed to photosynthesis; heating means for heating to the temperature range in which the hemicellulose of the pulverized biomass raw material is pyrolyzed so as to exhibit bonding effects; pressurization means for, in the state of the heating, pressurizing to the pressure range in which the lignin of the pulverized biomass exhibits a thermal curing reaction and maintaining the pressure; and cooling means for cooling after maintaining the state of the pressurization. The apparatus further comprises temperature detecting means provided at the exit end of the region being heated by the heating means and regulation means for judging a reaction terminal point in accordance with the result of the temperature detection and regulating the timing for transfer from heating to cooling.
