Process for the preparation of distillates atmospheric from a hydrocarbon residual oil is obtained by distillation under vacuum.

摘要

P process for the preparation of one or more oils, atmospheric distillates of hydrocarbons. / p & & p & a vacuum residue is hydrotreated catalytically 2. The hydrotreated product is separated by distillation, in one or several atmospheric distillates and a residue. At least a portion of the residue 20 is separated by deasphalting in a deasphalted oil 21 and 22 in the asphalt. The oil deasphalted is catalytically cracked in one or several atmospheric distillates. At least 50% by weight of the asphalt is recycled to the catalytic hydrotreatment. / p & & p & application to the preparation of gasolines. / p
