BIOCOKE MANUFACTURING METHOD AND MANUFACTURING DEVICE

Title:

BIOCOKE MANUFACTURING METHOD AND MANUFACTURING DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/113679

Kind Code:

A1

Abstract:

Provided are a biocoke manufacturing method and device that enable the efficient production of biocoke in a short period of time. In the biocoke manufacturing method, fine biomass particles are packed in a reaction vessel, whereafter, in a substantially airtight state, the particles are pressure molded while being heated in a temperature and pressure range that give semi-carbonized or pre-semi-carbonized solids, and subsequently cooled. The biocoke manufacturing method involves a packing process in which, after fine biomass particles are loaded into a reaction vessel, a pressing member is lowered from the top of said reaction vessel to pack and press the fine biomass particles at a lower pressure than the aforementioned pressure range; a reaction process in which, after the pressure of the pressing member is increased and the fine biomass particles are pressed at a pressure within the aforementioned pressure range while the fine biomass particles are heated by a heating means to a temperature in the aforementioned temperature range and maintained at that temperature for a preset time period, a subsequent switch is made from the heating means to a cooling means for cooling the molding; and an extraction process in which the base of the reaction vessel is released after reducing the pressure of the pressing member, and the cooled molding is extracted.
