For over 50 years, the chemical industry had used solid phosphoric acid (SPA) or aluminum chloride catalysts to synthesize cumene from benzene and propylene. This approach was fundamentally changed by the recent introduction of Co.’s revolutionary Q-Max process. The Q-Max process represents a new generation of cumene technology based upon a highly-selective and stable zeolite catalyst developed by Co. s researchers. The process offers excellent cumene product quality at over 99.7 wt-% yield. The catalyst used in the Q-Max process can be regenerated repeatedly, avoiding the significant catalyst disposal problems associated with the older SPA and aluminum chloride catalyst systems. Compared to other cumene synthesis technologies, the Q-Max process offers better product quality, better heat integration, lower investment cost, and a far more rugged and reliable catalyst system. |
