Abstract
This invention relates to a process for the separation of fine catalyst particles from a hydrocarbon feedstock coming from a catalytic cracking unit by filtration through mineral barriers and a filtration loop. The process consists of filtering the feedstock through mineral barriers that are resistant to heat and have a porosity adapted to the minimum diameter of the particles to be retained. The porosity is generally between 0.1 and 100 microns.
