Additive systems increase olefin production

摘要

Engelhard's Maximum Propylene Additive (MPA) combines a distributed matrix structure (DMS) platform technology with ZSM-5-based additives in a single additive formulation.This system is claimed to allow higher propylene production from fluid catalytic cracking (FCC) units while maintaining the flexibility of applying additive systems.Since the DMS-based activity function is included,less catalyst dilution activity occurs when applied at high concentrations of additives.MPA allows higher propylene production with fewer trade-offs.
