a Comparison and validation of hydrocarbon droplet diameter (dp) from CFD-PBM simulations and those calculated via the empirical formula. b Comparison and validation of the overall mass transfer coefficient (kLa) from CFD-PBM simulations and those calculated via the semi-empirical formula. c Comparison and validation of interfacial mass transfer flux of isobutane (Nisobutane) from CFD-PBM simulations and those calculated via the empirical formula. d The dp distribution of the H2SO4-catalyzed isobutane alkylation as a function of PPG400 concentration. e The kLa of the H2SO4-catalyzed isobutane alkylation as a function of PPG400 concentration. f The Nisobutane of the H2SO4-catalyzed isobutane alkylation as a function of PPG400 concentration. Interfacial parameters acquired from the I/O ratio of 16:1 system. Error bars represent the propagated deviation originating from statistical error in MD-calculated liquid–liquid interfacial tension. No independent experiments were performed.
