Mass transfer limitations in microchannel reactors - ScienceDirect

WebThe calculations showed that the first channel is more kinetically favourable (Δ G‡ ≈ 5.7–5.9 kcal/mol). Meanwhile, the domino products 6 are more thermodynamically stable than 5 (Δ G‡ ≈ 4.2-4.7 kcal/mol) and this fact may … WebInternal mass transfer limitation: refers to the catalyst structure and characterization that affects two factors [30]: • The diffusion of reactants and products in and out of the interior of the photocatalyst particle. • The light penetration inside the photocatalyst volume. Webboth the mass-transfer limited current, I lim, and the kinetically limited current, I kin, according to the follow-ing equation: 1=I ¼ 1=I lim þ 1=I kin: ð3Þ The mass-transfer can be changed by (i) varying the rotation speed using RDE or (ii) varying the concentra-tion of the substrate in the solution. I kin can be calcu- dod devsecops maturity model
