Preparation of a Synthetic Steamcracker Feedstock from Pyrolysis Gasoline on Zeolite Catalysts

摘要

With the advent of the Auto Oil Programme of the European Union, the aromatics content of gasoline has to be reduced significantly and, thus, an oversupply of aromatics is likely to occur. Therefore, the hydroconversion of aromatics-rich process streams, in particular of pyrolysis gasoline from naphtha, steamcrackers, into a high-quality synthetic steamcracker feedstock (composed mainly of ethane, propane and n-butane) at around 400 deg C and 6 MPa may become an attractive process.
