The Q-MAX™ process provides a very good cumene yield and quality. The QZ-2000 zeolite
based catalyst used in the Q-MAX™ process operates with a low flow rate of benzene and
hence investment and utility costs are reduced greatly. QZ-2000 is non-corrosive and
regenerable, avoiding the significant maintenance and catalyst disposal problems associated
with SPA and AlCl3 systems. Compared to other zeolite based cumene technologies, the QMAX™
process provides the highest product quality and great stability. Impurities in the
feed have less effect.
