What is the influence of catalyst as it related to oil-alcohol inter phase toward maximizing the yield of biodiesel production in hydrodynamic reactor?
Since the reactants mixture have interaction in hydrodynamic reactor, catalyst definitely increase the reaction rate...
Thank you for your wonderful contribution, Dr. Ramesh Desikan . Can the interaction be attributed to the ability of catalyst to enhance mass transfer and reduce inter phase between non-homogeneous mixture of the oil and alcohol?
There are limitations of mass transfer when heterogeneous catalysts are used during the transesterification of oils to produce biodiesel. Thus, well mixing efficiency is required for the solid-liquid phase to reduce external limitations. It is generally operated at a high temperature and with a high molar ratio of alcohol to oil to overcome the limitation of diffusion and equilibrium towards products.
you are asking about phase transfer, it is correct. the catalyst rate has not much influence on this, with the exception of having a catalyst with some surface activity. The obligated response is to look for phase transfer avoiding techniques (Boocock or QS Biodiesel), I am in favor of mine, the latest. Check kinetic specifics of reversible catalytic chemical reactions. Do not forget that a catalyst is not a reagent or substrate, neither a solvent
