OLEFIN UPGRADING WITH FERROSILICATE ZEOLITE CATALYST

摘要

A process for upgrading lower olefin to produce heavier hydrocarbons having a substantially linear molecular conformation comprising contacting olefinic feedstock under oligomerization conditions at reaction temperature and pressure favorable to formation of higher molecular weight aliphatic hydrocarbons with a shape selective medium pore acidic crystalline ferrosilicate zeolite catalyst having a major portion of zeolitic iron in tetrahedral coordination therein.
