“…The calculated value of the dimensionless Mears parameter was lower than 0.15, implying that the external mass transfer diffusion can be negligible in the kinetic study [33]. As listed in Table 3, the calculated Mears parameters at different temperatures were less than 0.15 which were in accordance with the experimental results.…”

“…On the basis of the dimensionless Mears parameter (C M ), theoretical calculation was used to examine the effect of the external mass transfer resistance on the conversion rate of FFAs [33]. where, ρ b is the bulk density of catalyst (g/mL), R c is the catalyst radius (m), n is the reaction order, C Ab is the bulk concentration of limiting reactant (mol/L) and κ c is the mass transfer coefficient (m/s) was expressed in the form of the Dwidevi-Upadhyay mass transfer correlation [28].…”

“…Hence, there exists a trade‐off between the high reaction rate due to the increased temperature and the decrease of the reaction rate, resulting from the vaporization of reactants. It is therefore essential to determine the optimal reaction temperature or temperature profile for efficient operation of the system considering the production rate as well as the vaporizing rate of reactants .…”

Kinetics of esterification of acrylic acid with ethanol in the presence of homogeneous (H2SO4, HCl, p‐TSA, HI) catalysts as well as heterogeneous catalysts (Dowex 50WX, Amberlyst 15) was studied. The effects and performance of these catalysts on the conversion of acrylic acid were evaluated. In the kinetics of homogeneous catalyzed reaction, both concentration and activity‐based model were employed. Activity coefficients were predicted by the Universal Functional group Contribution (UNIFAC) method to consider nonideal behavior of the liquid phase. The heterogeneous catalyzed reaction mechanisms were developed using Eley–Rideal theory. The model results were compared with the experimental results and were in good agreement. The temperature dependency of the constants, reaction enthalpy, and entropy, and activation energy were determined. The conversion of acrylic acid was obtained as 63.2%, 61.02%, 53.3%, 21.4%, 34.96%, and 14.84% for H2SO4, p‐TSA, HCl, HI, Dowex 50WX, and Amberlyst 15, respectively, under process temperature of 70°C, reactant molar ratio of 1:1, and catalyst concentration of 2% (v/v) for homogeneous and 2.17 g for heterogeneous catalyst. These outcomes provide an approach to understand the significant effect of each catalyst on the esterification kinetics of acrylic acid and ethanol.

“…The coefficients of determination (R) are also displayed in Table . In future work we intend to develop a Langmuir–Hinshelwood model for catalytic reactions to further discuss in detail the mechanism of the esterification and intrinsically link the result of catalyst characterization to butyl butyrate formation as has been done by Li et al …”

BACKGROUND: Butyl butyrate is an environmentally friendly biofuel component that can be produced through the esterification of butyric acid with n-butanol, both of which are obtainable from waste products. The reaction can be optimized by commercial catalysts; however they are currently hindered by issues such as environmental sustainability and cost. Thus, efforts have been made to develop catalysts with green characteristics by incomplete carbonization and sulfonation of pyrolysis products.
