Abstract

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.

First claim

What is claimed is:

1 . An unsaturated hydrocarbon production apparatus, comprising:
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.

2 . The unsaturated hydrocarbon production apparatus according to claim 1 , further comprising a cooling unit configured to rapidly cool a generated gas generated in the heating furnace to 600° C. or less.

3 . The unsaturated hydrocarbon production apparatus according to claim 1 , wherein the heating furnace accommodates a catalyst for accelerating a reaction of the raw material gas to any one or both of ethylene and acetylene.

4 . The unsaturated hydrocarbon production apparatus according to claim 1 , further comprising a preheating unit configured to preheat the raw material gas with heat released from the heating furnace.

5 . The unsaturated hydrocarbon production apparatus according to claim 4 , further comprising a first heat exchange unit configured to subject the generated gas generated in the heating furnace and the raw material gas to heat exchange,
wherein the raw material gas subjected to heat exchange in the first heat exchange unit is introduced into the preheating unit.

6 . The unsaturated hydrocarbon production apparatus according to claim 4 , further comprising a second heat exchange unit configured to subject the generated gas generated in the heating furnace and the raw material gas preheated by the preheating unit to heat exchange.

7 . The unsaturated hydrocarbon production apparatus according to claim 1 , further comprising a separation unit configured to separate ethylene or acetylene from the generated gas generated in the heating furnace.

8 . The unsaturated hydrocarbon production apparatus according to claim 1 , wherein the heating furnace is configured to heat the raw material gas to 1,000° C. or more and 1,200° C. or less.
