Abstract (en)

[origin: WO0029509A1] A dual functional catalyst is used to produce low sulfur gasoline from olefinic naphthas at relatively low pressure with minimal loss in road octane number. The dual functional catalyst uses a Group VI and/or a Group VIII metal on a suitable substrate for hydrodesulfurization and a zeolite for cracking. One such combination is a Cobalt Molybdenum/ZSM-5 catalyst. At low pressure, the catalytic reaction favors olefin cracking instead of olefin saturation from metals to improve product yields and enhance the octane number.
