Title:

METHOD FOR DIRECTLY SYNTHESIZING MONOCYCLIC AROMATIC COMPOUND AND LONG-CHAIN OLEFIN COMPOUND FROM CARBON DIOXIDE-RICH SYNTHETIC GAS

Document Type and Number:

WIPO Patent Application WO/2016/111463

Kind Code:

A1

Abstract:

The present invention relates to a method for directly synthesizing a monocyclic aromatic compound and a long-chain olefin compound from a carbon dioxide-rich synthetic gas and, more specifically, to a method for directly synthesizing a monocyclic aromatic compound and a long-chain olefin compound from a carbon dioxide-rich synthetic gas, the method comprising a step of preparing a C1-C15 short-chain hydrocarbon by Fischer-Tropsch (FT) synthesis and a step of preparing a monocyclic aromatic compound and a long-chain olefin compound by dehydrogenating the prepared short-chain hydrocarbon, and having effects of maximizing the yield of the short-chain hydrocarbon by using, as a synthetic gas to be used in FT synthesis, a carbon dioxide-rich synthetic gas in which the molar ratio of hydrogen, carbon monoxide and carbon dioxide is delimited to a specific range, and maximizing the yield of the monocyclic aromatic compound or the long-chain olefin compound by specifying the composition of a catalyst to be used in the dehydrogenation and the temperature and pressure condition.
