What is Two-Catalyst Olefin Production Process about?
This patent describes a two-catalyst process for making olefins, particularly ethylene and propylene, from an oxygenate feedstock. The process uses two zeolite catalysts - a first catalyst containing ZSM-5, and a second catalyst containing a 10-ring molecular sieve such as ZSM-22, ZSM-23, ZSM-35, or ZSM-48. The ZSM-5 catalyst can be unmodified, phosphorus-modified, or steam-modified. The two catalysts convert the oxygenate feed to olefins in two separate reaction stages.
