Abstract
A process for the production of low sulfur, low nitrogen fuels at low hydrogen consumption by splitting a feed into two components, a high boiling component, suitably a 1050.degree. F.+ fraction, and a low boiling component, suitably a 1050.degree. F.- fraction, and processing the two different components over two different types of catalysts, at different severities. Suitably, on the one hand, the high boiling component is treated over a large pore metal hydrogenation catalyst at severity sufficient to convert at least 30 percent, preferably at least 50 percent of the feed, based on the weight of the feed, to a 1050.degree. F.- product. The 1050.degree. F.- product from the conversion over the large pore metal hydrogenation catalyst is then blended with the low boiling component split from the original feed, and the blended low boiling material is then treated at low severity over a small pore metal hydrogenation catalyst to hydrodesulfurize and hydrodenitrogenate said low boiling components. The product of the hydrodesulfurization, hydrodenitrogenation reaction constitutes a suitable feed for hydrocracking, or for use as a catalytic cracker feed.
