Removal of sulfur oxides and particulates with copper-containing absorbers

Patent ·
OSTI ID:5241084

This patent describes a gas purification process, comprising the steps of: cracking a hydrocarbon feedstock in a reactor of a catalytic cracking unit in the presence of a cracking catalyst under catalytic cracking conditions to produce an upgraded cracked product leaving spent cracking catalyst; regenerating the spent cracking catalyst in a regenerator; emitting regenerator particulate-laden off-gases comprising sulfur oxides and cracking catalyst particulates from the regenerator; and passing the regenerator particulate-laden off-gases generally downwardly through a substantially vertical conduit of a granular bed filter and scrubber.
