Abstract
Beads for use in beds in electrostatic separators for the separation of suspended particles from hydrocarbon oils. Electrostatic separators employing a bed of these beads have the capacity to remove as much as 99 weight percent of contaminating particles, such as catalyst fines, from various oil fractions to levels of less than 100 parts per million and even less than 5 ppm. A method and apparatus for purifying various FCC oils using these beads is also provided.
