Selvidge, C W

An asphaltic, hydrocarbonaceous charge stock, containing more than about 2.0 percent by weight of sulfur and more than about 150 ppM by weight of metallics, is converted to a low-sulfur fuel oil in a plurality of catalytic conversion zones. The charge stock is initially separated to provide a light fraction and an asphaltic-containing heavy fraction. The latter is subjected to deasphalting to provide a deasphalted oil, containing from 30--100 ppM of metallics, and precipitated asphaltics. The light fraction and deasphalted oil are individually subjected to hydrodesulfurization in separate reaction systems. The fuel oil product, in admixture with the precipitated asphaltics, has a sulfur concentration less than about 1.0 percent by weight. 4 Claims, 1 Drawing Figure (auth)
