Abstract
<PICT:0782791/III/1> Petroleum oils which contain metallic contaminants, particularly nickel compounds, are purified by subjecting the oil to distillation or coking and bringing the vapours into intimate contact with a counter-current flow of asphaltic oil having an initial boiling-point above 1050 DEG F., whereby the metallic contaminants are extracted by the asphaltic oil, and a metal-free gas oil, suitable for catalytic cracking, is obtained as distillate. Heavy virgin stocks obtained by solvent precipitation from petroleum having a low content of metallic contaminants may in some cases be used as refluxing agent; thermal tars separated from the products of a thermal cracking unit may also be used; but "synthetic asphalts" separated from the products of a cat. cracking process are the preferred agents. A residual oil is introduced through line 46 into coker 45, which may contain a fluidized bed of coke particles at temperatures of 800 DEG to 1000 DEG F. The vapours produced in the coker are introduced into tower 48 where they are scrubbed with heavy catalytic tar, introduced through line 57. The vapours withdrawn from the head of the scrubbing tower are subjected to catalytic cracking in reactor 50. The cracked products are fractionated in vacuum distillation tower 52; and light-boiling products are withdrawn through lines 53, 54, 55 and 56. Heavy catalytic tar is withdrawn from the base of tower 52, and is conveyed to scrubbing tower 48 via line 57. The heavy liquid withdrawn from the base of tower 48 is passed to coker 45.
