Separation of nitrogen and methane via periodic adsorption
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1971-03)
The periodic process utilizes a rapid pressure swing cycle in an adsorbent bed to effect the separation of gas mixtures. During the first portion of a cycle the compressed gas mixture flows into the adsorbent-filled column. ...
Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
LETTER TO THE EDITOR: Efficient measurement of the percolation threshold for fully penetrable discs
(IOP Publishing Ltd, 2000-10-27)
We study the percolation threshold for fully penetrable discs by measuring the average location of the frontier for a statistically inhomogeneous distribution of fully penetrable discs. We use two different algorithms ...
Kinetics of phenol oxidation in supercritical water
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1992-03)
Aqueous solutions of phenol were oxidized in a flow reactor at temperatures between 300 and 420°C (0.89 < T r < 1.07) and pressures from 188 to 278 atm (0.86 < P r < 1.27). These conditions included oxidations in both ...
Transpiration-based micropump for delivering continuous ultra-low flow rates
(IOP Publishing Ltd, 2003-03-01)
In this paper we describe the design, construction and operation of a micropump that delivers continuous, ultra-low flow velocities at ∼100 μm s−1. The pumping concept is based on the commonly observed phenomenon of ...
Mass transfer in engineering practice, By Aksel L. Lydersen, Published by John Wiley & Sons, April 1983, 321 pp. $39.95
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1985-01)
No Abstract.
Self-sustained oscillations in a heterrogeneous catalytic reaction: a monte carlo simulation
(Elsevier, 1989)
We have utilized Monte Carlo methods to study the kinetics of a generic heterogeneous catalytic reaction, A+B-->AB. This reaction includes the elementary steps of adsorption and desorption of reactants A and B, surface ...
Proof of crossing formula for 2D percolation
(IOP Publishing Ltd, 1995-11-21)
The author`s recently conjectured expression (ibid., vol. 28, p. 1249, 1995) for Cardy`s (1992) crossing formula in 2D percolation is rewritten in terms of theta and elliptic functions and verified explicitly. Exact results ...
The role of conduction/valence bands and redox potential in accelerated mineral dissolution
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1986-10)
The dissolution kinetics of a number of manganese oxides in acidic solutions were studied. Using a slurry reactor, rate laws were determined for each of the manganese oxides in the hydrohalogen acids. Significant variations ...
Molybdenum carbide catalysts for water–gas shift
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 2000-12)
Molybdenum carbide (Mo 2 C) was demonstrated to be highly active for the water–gas shift of a synthetic steam reformer exhaust stream. This catalyst was more active than a commercial Cu–Zn–Al shift catalyst under the ...
