Abstract

Abstract Residual oil fractions are upgraded in that CCR is selectively removed without undue hydrogen consumption by hydroprocessing with a catalyst comprises a single metal such as molybdenum, tungsten, nickel, iron or palladium or multimetallic combination of such metals, excluding, however, active desulfurization compositions such as nickel molybdenum and nickel-tungsten. Said catalyst is characterized as having greater than about 50% of its pore volume contribution in pores having diameters in the range of between about 100 and 200 Angstroms. The product of such hydroprocessing is a particularly preferable feedstock for coking to give more liquid yield and less coke make.
