Abstract
Abstract A copper exchanged zeolite cracking catalyst capable of producing high octane gasoline of increased aromatic and olefinic content. Mixtures of copper and hydrogen ions are exchanged into a Y-type zeolite using a combination of exchange and calcination steps. The exchanged zeolite is advantageously combined with a major portion of inorganic oxide matrix to produce a catalyst suitable for use in standard commercial fluid and moving bed catcracking units.
