Method and system for synthesizing liquid hydrocarbon compounds

摘要

Provided is a method for synthesizing liquid hydrocarbon compounds wherein synthesizing liquid hydrocarbon compounds from a synthesis gas by a Fisher-Tropsch synthesis reaction. The method includes a first absorption step of absorbing a carbon dioxide gas, which is contained in gaseous by-products generated in the Fisher-Tropsch synthesis reaction, with an absorbent, and a second absorption step of absorbing a carbon dioxide gas, which is contained in the synthesis gas, with the absorbent which is passed through the first absorption step.

1. A method for synthesizing liquid hydrocarbon compounds comprising:
a synthesis step of synthesizing liquid hydrocarbon compounds from a synthesis gas containing carbon monoxide gas and hydrogen gas by a Fisher-Tropsch synthesis reaction in a reactor; a discharge step of discharging gaseous by-products formed by the Fisher-Tropsch synthesis reaction from the reactor; a first absorption step of absorbing carbon dioxide gas contained in the gaseous by-products discharged from the reactor with a first absorbent; and a second absorption step of absorbing carbon dioxide gas contained in the synthesis gas to be supplied to the reactor, with a second absorbent; and a supply step of supplying the first absorbent which has passed through the first absorption step to the second absorption step as the second absorbent.
