Synthesis of Hydrocarbon Fuels From Dimethyl Ether Through Co‐Oligomerization of Olefins
ABSTRACT This work investigates the impact of higher olefins and typical impurities from a preceding Dimethyl ether‐to‐Olefins (DtO) process on olefin oligomerization for fuel production. Feed complexity was systematically increased to mimic a DtO product containing lower and higher olefins as well as paraffinic and aromatic components. Higher olefins incorporation enhanced the yield of C 13+ hydrocarbons, while impurities reduced it. Kerosene was the dominant product fraction. Temperature was determined to be the governing parameter for promoting C 13+ formation and increasing diesel fuel yields, surpassing feed composition effects. Several key properties of the kerosene fraction comply with the ASTM D7566 22a standard for sustainable aviation fuels, whereas some important properties of the diesel fraction meet the ISO 8217 DMB grade for marine diesel fuel.
