Title:
MANUFACTURING METHOD OF SOLID FUEL
Document Type and Number:
Japanese Patent JP2020132805
Kind Code:
A
Abstract:
To provide a manufacturing method for manufacturing a solid fuel which is safe on burning from a waste plastic as a raw material.SOLUTION: In the manufacturing method of a solid fuel, a solid fuel is manufactured by treating a plastic-based waste containing multiple kinds of plastics in a treatment space of a closed vessel by a temperature rising process, a temperature holding process, and a cooling process including treatment process, in which manufacturing method of a plastic-based solid fuel is characterized by that: in the temperature rising process, a temperature rising rate in the closed vessel to 7-12°C/min is set by using a high-temperature high-pressure water vapor; in the temperature holding process, a subcritical state having a temperature to 120°C or over and 175°C or under, and a pressure of 12-15atm is set in the closed vessel and a subcritical water treatment process is performed to a plastic-based waste by agitation in the subcritical state for 15-35 min for dissolution of several kinds of plastics among the plastic-based waste containing multiple kinds of plastics, allowing them to deposit around remaining other plastic and solidify; and in a cooling process, the obtained is cooled.SELECTED DRAWING: Figure 2
