1. An unsaturated hydrocarbon production apparatus, comprising:
a light collecting device configured to collect sunlight, and to convert the sunlight into solar heat;
a heating furnace configured to heat a raw material gas containing at least methane and hydrogen with the solar heat generated by the light collecting device to 700° C. or more and 2,000° C. or less; and
a source of the raw material gas,
wherein
an amount of the hydrogen in the raw material gas is 3 mol or more and 8 mol or less per 1 mol of the methane in the raw material gas,
the heating furnace includes a tube and a furnace chamber,
the tube comprises a first part, a second part, and a third part that is provided between the first part and the second part,
the first part is connected to the source of the raw material gas,
the second part is connected to a send destination of the generated gas,
the first part and the second part are located outside the furnace chamber,
the third part is located in the furnace chamber, and the flow passage sectional area in the third part is smaller than the flow passage sectional area in the first part and the second part.
