Investigation on catalytic distillation for ethyl acetate production with different catalytic packing structures

Zhiwei Wang et al.

Summary: The catalytic packing plays a critical role in catalytic distillation, with the catalyst's presence in the packing influencing the process significantly. To analyze the impact of catalyst packings on catalytic distillation, the ethyl acetate reactive distillation system was studied, comparing a supported catalytic packing (SCP) with a conventional tea-bag catalytic packing (TBP). Laboratory experiments showed that the SCP had higher ethyl acetate conversion at a low catalyst loading. The effects of reaction kinetics, mass transfer performance, and actual catalytic efficiency of the packings were considered and investigated through experiments and numerical simulations, highlighting the role of relatively immediate in-situ separation caused by rapid reaction kinetics and improved mass transfer performance of SCP in the conversion rate difference.
