Kinetic study of liquid phase esterification of lactic acid with n-amyl alcohol catalyzed by cation exchange resins: experimental and statistical modeling

Thermodynamic and Kinetic Study on the Catalysis of Isoamyl Acetate by a Cation-Exchange Resin in an Intensified Fixed-Bed Reactor

Kinetics and thermodynamics of esterification by a cation-exchange resin in an intensified fixed-bed reactor was studied systematically. The resin type, catalyst loading, volume flow rate, initial molar ratio, temperature, and catalyst reusability were studied and optimized. The nonideality of the reaction system was corrected by the UNIFAC group contribution method. The Δ_r H ⁰, Δ_r S ⁰, and Δ_r G ⁰ of the reaction were acquired by two methods. The pseudo-homogeneous (PH) model and the Langmuir-Hinshelwood-Hougen-Watson (LHHW) model were adopted to simulate the kinetic process. The result indicated that the LHHW model was better suited to simulate the kinetic process than the PH model.

Kinetic study of esterification over structured ZSM-5-coated catalysts based on fluid flow situations in macrocellular foam materials

Kinetics on the structured catalysts exhibited strong dependency on a fluid flow characteristic (e.g., Re number). The results can guide the design of structured catalytic packing in the applications of the reaction distillation (RD) process.
