- Optimal design on an economic basis for continuous stirred tank reactors in series using michaelis-menten kinetics for ping-pong reactionsPublication . Malcata, F. XavierA theoretical analysis of the reactant concentration profile along a given number of CSTR's in series for ping-pong type reactions following Michaelis-Menten kinetics (with equal initial concentrations for both substrates) has been developed. Minimising the total holding time was taken as the intermediate objective function whereas minimising the total capital investment was assumed to be the main objective function.

- Double surface-renewal model for the prediction of mass transfer rates during bubble formation with instantaneous reaction on the liquid sidePublication . Malcata, F. XavierDesorption of a component from a gas mixture being injected through a submerged nozzle, during the bubble formation stage, is theoretically studied. The solute is assumed to suffer an instantaneous reaction on the liquid side, the reaction plane being on the liquid/gas interface. The volume elements on the gas bubble are assumed to result from a forced surface renewal coupled with a natural surface renewal, both achieved via gas elements with fresh composition. A surface residence time distribution is thus obtained, and desorption rates are calculated from the relevant variables, assuming non-steady state, unidimensional diffusion in a semi-infinite medium as the main mass transfer mechanism. Comparison of the model with experimental data is reported, physical evidence being predicted better than with previous models.
