ABSTRACT:
Light cycle oil (LCO) is upgraded to a low sulfur gasoline by co-processing the LCO with a cracked, sulfur-containing olefinic naphthas by hydrodesulfurization followed by treatment over an acidic catalyst comprising zeolite beta with a metal hydrogenation component such as molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The zeolite beta catalyst is active for conversion of the higher boiling portions of the feed to products of low sulfur content in the gasoline boiling range.
