An unsaturated hydrocarbon production apparatus includes: a light collecting device configured to collect sunlight, and to convert the sunlight into solar heat; and a heating furnace configured to heat a raw material gas containing at least any one selected from the group consisting of methane and hydrogen, methane and oxygen, and ethane with the solar heat generated by the light collecting device to 700° C. or more and 2,000° C. or less.

Unsaturated hydrocarbon production apparatus

A hydrogen production apparatus includes: a first furnace configured to heat a mixed gas of a raw material gas, which contains at least methane, and hydrogen to 1,000&#xb0; C. or more and 2,000&#xb0; C. or less; and a second furnace configured to accommodate a catalyst for accelerating a reaction of a first gas generated in the first furnace to a nanocarbon material, and to maintain the first gas at 500&#xb0; C. or more and 1,200&#xb0; C. or less.

Hydrogen production apparatus and hydrogen production method

A recovery apparatus of carbon dioxide includes: an absorption column contacting a carbon dioxide-containing gas into contact with an absorbing liquid and allowing the absorbing liquid to absorb carbon dioxide; a regeneration column for regenerating the absorbing liquid to release carbon dioxide; a circulation system which circulates the absorbing liquid to flow from the absorption column and return to the absorption column through the regeneration column; and a steam supply system which generates steam available for a heat source that regenerates the absorbing liquid, using the absorbing liquid that returns to the absorption column and/or the absorbing liquid in the absorption column, and supplies the steam to the regeneration column. High temperature steam is generated from the absorbing liquid and is provided to the regeneration column to use as a heat source for regenerating the absorbing liquid.

Method of recovering carbon dioxide and recovery apparatus

A gasification furnaceis divided into a plurality of gasification furnace unitsandeach of which has an inleton a lower portion at a longitudinally upstream end in a direction of travel of raw and bed materials and has an outleton an upper portion at a longitudinally downstream end in the direction of travel. The outletis connected to the inlet. The inletis fed with a raw material and a hot bed material from a materials separator. The inletis also fed with the hot bed material from the material separator. The outletis connected to a combustion furnace
