Abstract
A process for producing a desulfurized gasoline boiling range product of relatively high octane number from a sulfur containing feed boiling in the naphtha boiling range by converting the feed in a first stage over a conventional hydrodesulfurization catalyst, and then converting at least the normally liquid portion of the product of this first stage conversion over a catalyst comprising a zeolitic behaving refractory solid having acid activity and shape selectivity to produce a product having a sulfur content within the required specifications, and an octane number which at least approaches the octane number of the feed.
