Abstract
Heavy asphaltenic oils are converted to lighter fractions by PA0 (a) Deasphalting the asphaltenic oil with an aliphatic C.sub.5 -C.sub.7 hydrocarbon, PA0 (b) Maintaining the oil with hydrogen at 440.degree.-530.degree. C. and 40-140 bars in a non-catalytic conversion zone, and PA0 (c) Feeding the product of step (b) to a catalytic conversion zone at 320.degree.-430.degree. C. and 40-140 bars, the catalyst in said zone comprising at least one molybdenum and/or tungsten compound and at least one nickel and/or cobalt compound.
