Abstract
The present invention relates to the conversion of saturated paraffin hydrocarbons having 4 or more carbon atoms to olefins having fewer carbon atoms. In particular, the invention provides for contact of a mixture of 40 to 95 wt % paraffin hydrocarbons having 4 or more carbon atoms and 5 to 60 wt % olefins having 4 or more carbon atoms with solid zeolitic catalyst such as ZSM-5 at conditions effective to form propylene and the separation of light olefins from the reaction mixture.
