Equilibrium-limited periodic separating reactors
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1987-08)
A new unit operation is presented that utilizes a rapid feed pressure swing cycle in a bed packed with catalyst and adsorbent to effect both reaction and separation. This hybrid device combines features of a cyclic-steady-state ...
On the extension of the model of matrix acid stimulation to different sandstones
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1976-07)
A model was developed for the acidization of various sandstone cores which successfully describes the flow and reaction in the porous media during acidization. A comparison of the experimental results of various investigators ...
Small angle X-ray scattering from coal-derived liquids
(Elsevier, 1982-05)
Small angle X-ray scattering measurements were used to determine the size and shape of asphaltene and preasphaltene micelles in solution. The fraction of the coal-derived liquids forming micelles in solution was as high ...
Desorption by ultrasound: Phenol on activated carbon and polymeric resin
(Wiley Subscription Services, Inc., A Wiley Company, 1998-07)
An experimental feasibility study of using ultrasound to accomplish the dificult desorption of phenol from activated carbon and polymeric resin adsorbents is discussed. The desorption rates of activated carbon were found ...
Laminar Newtonian jets at high Reynolds number and high surface tension
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1988-09)
No Abstract.
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Solubility inversion effects on diffusion from collapsing bubbles
(Elsevier, 1971-09)
This work discusses the dissolution of gas bubbles in liquids subjected to a sudden pressure surge, as well as lending insight to studies on rectified diffusion. The bubble growth rates for rectified diffusion under ...
The effects of exopolymers on cell morphology and culturability of Leuconostoc mesenteroides during starvation
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Biofilm formation by bacterial cells can be used to modify the subsurface permeability for the purpose of microbial enhanced oil recovery, bio-barrier formation, and in situ bioremediation. Once injected into the subsurface, ...
Recuperative parametric pumping in adsorptive membranes
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1996-01)
Recuperative parametric pumping in adsorptive membranes, a cyclical adsorptive separation process, can lead to two distinct mechanisms of separation: rejection and preferential transport. During rejection, the adsorptive ...
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
