Gravity-induced flocculation
(Elsevier, 1984-09)
In polydisperse colloidal systems, flocculation can occur as a result of the differential creaming rates between small and large particles. As an improvement on earlier work, we have rigorously modelled this process of ...
CO oxidation of Pt/Al2O3 and Pd/ Al2O3 transient response and concentration cycling studies
(Elsevier, 1986)
By combining transient response experiments with forced concentration cycling, we were able to determine the reactive surface intermediates responsible for the large rate enhancements observed during periodic operation. ...
Periodic separating reactors: Experiments and theory
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1989-05)
The novel combination of a pressure swing adsorber (PSA) with a periodic flow-forced packed-bed reactor is explored. The device provides integral component separation and reaction. Feed sequences studied for the periodic ...

Co oxidation on Pd/Al2O3. Transient response and rate enhancement through forced concentration cycling
(Elsevier, 1986)
Catalytic oxidation of CO over Pd/Al2O3 was studied with a novel monolithic reactor, with inside the reactor detection of reactants and products. Periodic switching of the feed between CO/N2 and O2/N2 resulted in time-averaged ...
Monomer-addition growth with a slow initiation step: A growth model for silica particles from alkoxides
(Elsevier, 1989-10-01)
A simplified monomer-addition model with a first-order activation step is developed to describe the dynamics of growth of silica particles from alkoxides. In the limit of slow hydrolysis, we obtain expressions for the ...
Emulsion stability--theoretical studies on simultaneous flocculation and creaming
(Elsevier, 1981-07)
A general dynamic equation is derived describing the behavior of a polydispersed emulsion in which Brownian flocculation, sedimentation-flocculation, and creaming are taking place simultaneously. The resulting equation ...
Spectroscopic and scattering investigation of isopoly-molybdate and tungstate solutions
(Elsevier, 1984)
Detailed spectroscopic and scattering investigations of isopoly-molybdate and -tungstate solutions as a function of concentration and pH were made. From scattering results the apparent molecular weights were determined as ...
Competition among flow, dissolution, and precipitation in porous media
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1989-07)
A theoretical and experimental study has been carried out on flow, dissolution, and precipitation in porous media. Flow experiments were performed on linear carbonate cores using acidic ferric chloride solutions. Dissolution ...
