Title:
二酸化炭素の有機物化処理方法
Document Type and Number:
Japanese Patent JP4044990
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a treating method for transforming carbon dioxide into an organic material, by which the carbon dioxide (CO2 ) is transformed into a reusable organic material by an industrially feasible method by reducing the carbon dioxide with hydrogen by a hydrothermal reaction by using an iron component as a catalyst, etc., and water as a hydrogen source under saturated steam pressure. SOLUTION: CO2 is supplied to a hopper 1 from a supplying line 2, and water of >=2 molar times as much as the number of moles of the CO2 is supplied from a water-supplying line 3. The supplied CO2 and water are formed into a aqueous solution state in a mixing line 4, and a pulverized slag consisting essentially of FeO, etc., is fed to the mixture in the aqueous solution state. The obtained mixture is kneaded by an agitator 9 to provide a slurry. The obtained slurry coming through a valve 10 is pressurized by a slurry pump 5 to 100-400 atm, and introduced into a reaction tube 7 at a temperature kept by a heater 6. A hydrothermal reaction of the slurry is carried out in the reaction tube 7 at about 300-400 deg.C under a saturated steam pressure to reduce the CO2 with hydrogen to provide an organic material such as methanol and propane.
