Additive-mediated interfacial engineering of H2SO4-catalyzed isobutane alkylation from molecular design to industrial process intensification

from apparent kinetic model, mass transfer-free kinetic parameters of isobutane alkylation are determined, quantitatively confirming the reaction is mass transfer controlled. Additive-mediated process intensification reveals PPG400 additive increases alkylate capacity by 24.85% up to 99.83 kt/a from 79.96 kt/a in additive-free system.
