European refiners can produce good quality fluid catalytic cracking (FCC) feedstocks by deasphalting vacuum residue with propane, butane, or pentane. Propane deasphalting is the least expensive route because no hydrotreatment of the deasphalted oils (DAO) is required. Butane and pentane deasphalting is more difficult because these heavier feeds must be upgraded via hydrotreating to achieve suitable Conradson carbon and metals contents, and the pitch resulting from deasphalting must be effectively utilized. But all three solvent deasphalting approaches can produce suitable FCC feeds at acceptable economics. The investment required for this conversion route is lower compared to direct hydroconversion, and more flexible than the conventional coking route. The European Economic Community (EEC) and France, as examples, have increased FCC capacity while decreasing distillation capacity, as a result of changing worldwide demand for petroleum products. Thus it is now possible to consider that some FCC overcapacity exists, tightening supplies of conventional vacuum gas oil (VGO) FCC feedstocks.
