Catalyst evaluation using an ARCO pilot unit on North Sea atmospheric residue

Paper in proceeding, 2009

Most North Sea atmospheric residues are well suited feedstocks to a residue fluid catalytic cracker (RFCC) due to their low metals and asphalthene contents. StatoilHydro have used the circulating ARCO pilot unit at Chalmers University of Technology for pilot scale testing of catalysts and feedstocks since 1984. A comparison with the commercial RFCC unit showed that the converted ARCO unit works quite well and we are confident in the results. This will be exemplified with different cases that have happened since the project started.
