Abstract:
1. A method for thermo-chemical gasification, utilization, and recycling of a feedstock including a carbon content solid waste or a solid mixture of at least one organic and one inorganic material, the method comprising: treating said feedstock during its gravity movement from a top section to a bottom section of a vertical column apparatus to facilitate drying, organic material's gasification, and inorganic material's melting processes; receiving an overheated steam from a steam-heater apparatus into a gasification zone of said vertical column apparatus in which said gasification of organic materials is performed; applying said overheated steam at a temperature of 1600° C.-1850° C. to said feedstock so as to separately discharging said liquid multi-component glassy slag and said liquid multi-metal alloy; evaporating water from said feedstock to produce an evaporated steam in said vertical column apparatus; cleaning said evaporated steam and then condensing said evaporated steam into a warm water; and separating said warm water into a first portion, a second portion and a third portion, wherein said gasification of said organic materials and said syngas production is performed concurrently with said utilization and recycling of said inorganic materials in the same vertical column apparatus in an atmosphere of said overheated steam and in the absence of air, oxygen, and catalysts.
