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 ...
Kinetic Separation of Oxygen and Argon Using Molecular Sieve Carbon
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
A pressure-swing adsorption (PSA) simulation study was performed for the separation of a mixture of 95% O 2 and 5% Ar using a molecular sieve carbon (MSC) as the adsorbent. Two PSA cycles have been outlined to maximize the ...
Monte Carlo simulation of the adsorption of co on pt(111): thermodynamic considerations for the surface configuration of adsorbed species
(Elsevier, 1991-02-02)
We have developed a "two-site" lattice gas model which provides a theoretical framework for understanding adsorption equilibrium in systems for which the potential energy surface is inherently heterogeneous in terms of ...

Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
The structure and function of supported molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1994-03)
A series of [gamma]-Al2O3 supported Mo nitrides were prepared by the temperature programmed reaction of supported molybdates with NH3. Several loadings, heating rates, and space velocities were employed in an attempt to ...
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 ...
Pt/MCM-41 catalyst for selective catalytic reduction of nitric oxide with hydrocarbons in the presence of excess oxygen
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1998-03)
First results are reported on the use of MCM-41 mesoporous molecular sieve as the support for Pt for the selective catalytic reduction of NO by hydrocarbons in the presence of O 2 . MCM-41 provided the highest specific NO ...
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 ...
