Abstract
A synthesis gas and nanocarbon production method has a lower hydrocarbon decomposition step for decomposing lower hydrocarbon to produce hydrogen and nanocarbon, a carbon dioxide reduction step for reacting a part of the nanocarbon produced with carbon dioxide to produce carbon monoxide, and a mixing step for mixing the hydrogen and carbon monoxide produced in a predetermined ratio, thereby nanocarbon and a synthesis gas having a desired gas ratio can be simultaneously produced easily.
Claims16
A synthesis gas and nanocarbon production method, comprising:
- a lower hydrocarbon decomposition step of directly decomposing lower hydrocarbon using a catalyst to produce hydrogen and nanocarbon;
- a carbon dioxide reduction step of reacting a part of the nanocarbon produced in the lower hydrocarbon decomposition step with carbon dioxide to produce carbon monoxide;
- and
- a mixing step of mixing the hydrogen produced in the lower hydrocarbon decomposition step and the carbon monoxide produced in the carbon dioxide reduction step in a predetermined ratio to obtain a synthesis gas.
A synthesis gas and nanocarbon production system, comprising:
- a lower hydrocarbon decomposition reactor, in which a lower hydrocarbon supply tube for supplying lower hydrocarbon is connected thereto, a catalyst is stored in a space communicated with the lower hydrocarbon supply tube, and the space is a reaction space where the lower hydrocarbon is directly decomposed;
- carbon monoxide production reactor, in which a carbon dioxide supply tube for supplying carbon dioxide is connected thereto, nanocarbon is stored in a space communicated with the carbon dioxide supply tube, and the space is a reaction space where the carbon dioxide is reduced to carbon monoxide;
- and
- a mixing equipment, which is connected to the lower hydrocarbon decomposition reactor and the carbon monoxide production reactor, and in which the hydrogen produced in the lower hydrocarbon decomposition reactor and the carbon monoxide produced in the carbon monoxide production reactor are mixed.
