Abstract
Deasphalting heavy, asphaltic crudes before significant thermal treatment, even mild treatment which is inherent in, e.g., vacuum distillation, produces deasphalted whole crude with a reduced soluble metal content. This process is especially effective for preparing feedstocks for catalytic cracking units from heavy crudes containing large amounts of Ni and V which are porphyrin coordinated, and which are thermally unstable.
