Title: Fixation method for carbon dioxide as inorganic carbon material by carbonization of organic matter
Inventor: MITOMA TATSUHISA
IPC: C02F11/10
Filed: 2011-03-23
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of carbon dioxides in the atmosphere since carbon of fossil fuel etc., fixed in organic matter through photosynthesis returns into the atmosphere as carbon dioxides through combustion etc., to cause global warming problems.SOLUTION: When organic matter is carbonized, fossil fuel is necessary as a heat source because of endothermic reaction as heat of decomposition, and carbon dioxides are discharged. The carbonization, however, is carried on by self-heating after temperature is applied in the beginning. The discharge of carbon dioxides of a carbonized product produced by a carbonization furnace which is smaller in heating value and carbon dioxide conversion value of warming gas such as generated carbon monoxides (NO) in carbide production than the carbon dioxide conversion amount of inorganic carbon as products becomes smaller than the carbon dioxide conversion amount of the inorganic carbon as the products. The difference thereof is an effective amount of soil-fixed carbon dioxides which can be reduced from the atmosphere so as to reduce carbon dioxides in the atmosphere.
