One embodiment is an improved process for economically converting carbo-metallic oils by means of catalytic particulates into lighter products, wherein a portion of the particulates is withdrawn and passed through a high strength magnetic field of at least 1 kG and field gradients of at least 10 kG/inch while conveyed on an electrostatic conducting belt to enable separation of the mass of particulates by inertia into at least two fractions; one of which has, in the case of catalyst, higher activity and lower metals content and is recycled back to the unit; a second higher metals, lower activity catalyst which is disposed of or treated for recovery of metals; and optimally, intermediate fraction which can be disposed of, or first treated to remove metals, and then chemically reactivated and returned to the unit. Another embodiment is an improved metals removal process employing very low activity sorbent to remove metals and Conradson Carbon, wherein a portion of said sorbent is withdrawn and passed through a high strength magnetic field of at least 1 kG, preferably at least 5 kG, and still more preferably at least 8 kG with a field gradient of at least 10 kG/inch and still more preferably a field gradient of at least 15 kG/inch that are generally in the range of about 10 kG/inch to 200 kG/inch, while conveyed on an electrostatic conducting belt, whereby at least two fractions of different metals levels are obtained.
