Pilot unit test of residue type catalysts on North Sea atmospheric residue
Paper i proceeding, 2009
In order to study the influence of the zeolite content and the matrix when a North Sea atmospheric residue was cracked, two state-of-the-art catalysts with the same zeolite and RE levels were investigated in the circulating ARCO pilot unit at Chalmers. The results from these tests showed that there was a limit in the size of the zeolite to matrix surface area ratio. The choice of matrix also influenced the product yields. The paper will also contain a review of the optimization studies of residue catalysts that the authors have performed during the years.
