Product Description
Product Brand
For liquid-phase, EBC-1/-2/-3
For vapor-phase, AB-12/-97 & SEB-08/-12/-18
Application
Liquid-phase ethylene to ethylbenzene unit
Vapor-phase ethylene to ethylbenzene unit
Description
The EBC catalyst is developed for benzene alkylation with pure ethylene in a liquid-phase, fixed-
bed reactor to produce ethylbenzene. SCM-1 zeolite is adopted as the active component for the
EBC catalyst. The delaminated SCM-1 zeolite possesses ultra-large external surface areas.
Therefore, the EBC catalyst exhibits excellent performance.
The AB catalyst is designed for benzene alkylation with pure ethylene in a vapor-phase, fixed- bed
reactor to produce ethylbenzene. The catalyst shows very stable performance in terms of ethylene
conversion and selectivity.
The SEB catalyst is developed for benzene alkylation with dilute ethylene from refinery offgas.
Contributed to the unique morphology of ZSM zeolite, the diffusion limitation is substantially
reduced. The undesired reaction to produce polyalkylbenzene and other byproducts is reduced,
leading to the improved activity and selectivity.
Advantages
> low reaction temperature
> Low benzene-to-ethylene ratio
> Long cycle length and service lifetime
