    摘要： Petroleum resid is upgraded in an improved process to produce a low pour point 650.degree.-775.degree. F. fraction without disturbing the product characteristics of other distillate boiling range fractions. The 650.degree.-775.degree. F. fraction is dewaxed separately from the remaining hydrodesulfurized product.

    摘要： A process for desulfurizing a delayed coker naphtha in a catalytic naphtha desulfurization process in which the feed comprising the delayed coker naphtha is passed over a silicon trap comprising a high surface area inert alumina of low metals content prior to being hydrodesulfurized in an olefin-retentive, catalytic naphtha hydrodesulfurization process. Unpromoted (no intentional metals content), inert alumina is preferred for the silicon trap since it will not affect the olefin-retentive qualities of the hydrodesulfurization catalyst and for maximal silicon capture, a high surface area alumina is employed.

    摘要： A system and method for producing fuels and lubricant basestocks from gas oil boiling range feeds is provided. Desulfurization and conversion stages are used to form fuel and lubricant products. The product from a desulfurization stage can be fractionated, and a portion of the fractionated bottoms can be used as an input feed for a conversion or hydrocracking stage. The configuration can advantageously allow for reduced amounts of catalyst in the conversion stage.

    摘要： Low sulfur gasoline of relatively high octane-barrel value is produced from cracked, sulfur containing olefinic naphthas by hydrodesulfurization at low temperature and low space velocity over either a conventional catalyst, such as CoMo/Al.sub.2 O.sub.3, or a dual functional catalyst, such as CoMo ZSM-5/Al.sub.2 O.sub.3. This approach also minimizes the olefins/hydrogen sulfide re-combination frequently observed at high temperature. The process produces a gasoline having a reduced sulfur content with a less than 5% change in motor octane number and a less than 10% change in research octane number.
