Claims
- 1. In an apparatus for magnetic separation for particulates comprising: a) a source of catalyst or sorbent containing magnetic materials from a hydrocarbon conversion process, in communication with; b) a magnetic separator having a moving element passing through a magnetic field, said moving element having a substantial horizontal momentum which is imparted to said particles, and having a deposit point at which particles move from said moving element to fall under the influence of gravity, and having a plurality of catching means for successively larger particles, and c) an additional oversize particle catching means for substantially oversized, substantially non-magnetic particles, said additional catching means being spaced from said moving element a distance in the direction in which said moving element imparts momentum to said particles; whereby oversized particles are separated into said oversized particle catching means.
- 2. An apparatus according to claim 1 wherein said moving element is a belt moving over a magnetic roller.
- 3. An apparatus according to claim 1 wherein said moving element is a disc moving through a magnetic field.
- 4. An apparatus according to claim 1 wherein said moving element is a magnetic roller or drum.
- 5. An apparatus according to claim 1 wherein said source comprises particulate selected from the group consisting of fluid catalytic cracking catalyst, fluidized sorbent, ebulating bed catalyst, moving bed catalyst, and fixed bed catalyst.
