Nonlinear frequency response of adsorption systems: isothermal batch and continuous flow adsorbers
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The problem of nonlinear frequency response of adsorption systems is treated using the concept of higher-order frequency response functions (FRFs). The FRFs on the adsorber and on the particle scale are considered. Based ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - I. A semi-batch adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A semi-batch mode of operation is considered, ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - II. A continuous flow adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A continuous mode of operation is considered, ...
Osmotic and activity coefficients of {yNaH(2)PO(4)+(1-y)Na2SO4}(aq) at the temperature 298.15 K
(Elsevier Science Bv, Amsterdam, 1999)
The osmotic coefficients of the mixed electrolyte solution {yNaH(2)PO(4) + (1 - y)Na2SO4}(aq) have been measured by the isopiestic method, at the temperature T = 298.15 K. The activity coefficients of NaH2PO4 and Na2SO4 ...
Synthesis of mullite nanostructured spherical powder by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
In this paper the synthesis of nanostructured spherical particles of mullite powders by ultrasonic spray pyrolysis is presented. The mullite crystallization and the nanostructure development during heating were examined ...
The polymerisation kinetics of lower dialkyl itaconates
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical polymerisation kinetics of diethyl- (DEI), dipropyl- (DnPI), dibutyl- (DnBI), and dihexyl itaconate (DHI) in the bulk were studied in the temperature range from 50 to 70 degrees C. The concentration of the ...
Flow regimes and liquid mixing in a draft tube gas-liquid-solid fluidized bed
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with ...
Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
Resistance parameters and water quench test as criteria of thermal shock behaviour of alumina based refractories
(Taylor & Francis Ltd, Abingdon, 1999)
The materials investigated were five alumina based commercial refractories with different contents of Al2O3 + TiO2 from 28 to 78%. Thermal (k thermal conductivity, alpha coefficient of thermal expansion) and mechanical (E ...
Electron microscopy observations of twin-twin intersections in a particle hardened copper-titanium alloy
(Scripta Materialia, 1999)
The twin-twin intersections in the precipitation hardened two-phase copper-titanium alloys were studied using conventional and high-resolution electron microscopy. The incident twin propagation through an obstacle twin was ...
