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, ...
Palm oil hydrolysis by lipase from Candida cylindracea immobilized on zeolite type Y
(Elsevier Science Inc, New York, 1998)
Lipase from Candida cylindracea immobilized on hydrophobic zeolite type Y was used to hydrolyze palm oil in a microaqueous two-phase reaction system containing isooctane as organic medium and lecithin as surfactant. The ...
Impact of plate types on refining and specific energy consumption
(Editura Acad Romane, Bucuresti, 1998)
Fibre refining is one of the most important stages of mechanical and chemical fibre treatment with direct impact on the quality of the final product-paper. The raw material to be refined and the requirements regarding the ...
Rheological behavior of cured acrylate-terminated unsaturated copolyesters
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
The viscoelastic properties of cured acrylate-terminated copolyesters were studied by means of dynamic mechanical analysis. The influence of terminal double bonds, as well as of the cis-trans configuration and distribution ...
The efficiency of an enzyme treatment in reducing wool shrinkage
(Taylor & Francis Ltd, Abingdon, 1998)
The influence of different experimental conditions, chosen according to a central rotatable plan (Box-Hunter) at three levels of treatment time, on the shrink-resistance properties of wool treated with serine proteinase ...
Kinetics of the reactions of pyridine and pyridine-N-oxide carboxylic acids and substituted benzoic acids with diazodiphenylmethane in various alcohols
(Sage Publications Ltd, London, 1998)
Solvent effects on the reactivity of pyridine and pyridine-N-oxide carboxylic acids and p-substituted benzoic acids in their reaction with diazodiphenylmethane (DDM) in alcohols have been investigated and the rate constants ...
The effect of growth rate on the structure of primary and secondary dendrites of single crystal of Ni based superalloy
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
So far, in our work aimed at obtaining single crystals of a Ni based superalloy, we have investigated the possibilities of obtaining single crystals using different methods as well as the influence of growth conditions, ...
2D model of pseudomorphic InGaAs/InAlAs HEMT's structure
(Trans Tech-Scitec Publications Ltd, Durnten-Zurich, 1998)
This paper presents the 2D model of the pseudomorphic InGaAs/InAlAs/InGaAs HEMT (High Electron Mobility Transistor) structure based on relevant physics. Together with parameters governed by the geometry and the producing ...
