Method of manufacturing oxygenated fuel

摘要

A Fischer-Tropsch reaction (10) is conducted using a synthesis gas of carbon monoxide and hydrogen as a raw material to synthesize hydrocarbons containing a large amount of olefin. These hydrocarbons are separated into a light fraction and a heavy fraction by means of a heat exchanger (12) and an oxo process (14) is conducted with respect to the olefin contained in the light fraction with a cobalt catalyst. As a result, an oxygenated fuel containing alcohol, aldehyde, etc. is manufactured. The oxygenated fuel made by such a manufacturing method is excellent in lubricity and oxidation stability, has a high cetane number, and is also capable of suppressing generation of soot when the oxygenated fuel is combusted. <IMAGE>
