Abstract
Systems and methods are provided for conversion of ethylene-containing feeds to fuels boiling range compounds, such as jet boiling range compounds. It has unexpectedly been discovered that improved conversion of ethylene-containing feeds can be achieved in a single stage at temperatures of 250° C. or less using a MWW framework catalyst that is substantially free of supported metals.
Claims20
A method of converting an ethylene-containing feed, comprising:
- exposing a feed comprising 5.0 wt % or more of ethylene to a catalyst comprising an MWW framework structure under conversion conditions comprising a temperature of 250° C. or less to form a conversion product comprising C9-C16 components,
- the catalyst comprising a) 0.75 wt % or less of Group 5-10 and Group 13 non-noble metals supported on the catalyst, and b) 0.05 wt % or less of Pt, Pd, or a combination thereof supported on the catalyst,
- the feed comprising a molar ratio of ethylene to isoparaffins of 1.0 or more and a molar ratio of ethylene to aromatics of 1.0 or more.
