Evaluation of periodic operation of a trickle-bed reactor based on empirical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this paper, we propose a new procedure for fast evaluation of the potential of periodic operations in trickle-bed reactors, based on empirical modeling. Step response experiments, with different input amplitudes, were ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Some practical aspects of nonlinear frequency response method for investigation of adsorption equilibrium and kinetics
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Some practical aspects regarding application of the nonlinear frequency response (NFR) method for investigation of gas adsorption: choice of the optimal mass of the adsorbent, frequency range and input amplitude, are studied ...
Estimation of competitive adsorption isotherms based on nonlinear frequency response experiments using equimolar mixtures-numerical analysis for racemic mixtures
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The nonlinear frequency response method for estimation of competitive adsorption isotherms, based on analysis of the response of a chromatographic column to sinusoidal perturbation of the inlet concentration, was modified ...
Nonlinear frequency response analysis of forced periodic operation of non-isothermal CSTR with simultaneous modulation of inlet concentration and inlet temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The nonlinear frequency response (NFR) method is applied for evaluation of possible improvement through simultaneous periodic modulation of two inputs of a non-isothermal continuously stirred tank reactor (CSTR) in which ...
Nonlinear Frequency Response measurements of gas adsorption equilibrium and kinetics: New apparatus and experimental verification
(Pergamon-Elsevier Science Ltd, Oxford, 2015)

Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Reactor conceptual design by optimization for hydrogen production through intensified sorption- and membrane-enhanced water-gas shift reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In this feasibility study, a novel industrial-scale reactor structure for continuous hydrogen production via intensified water-gas shift (WGS) reaction is proposed. It considers both trickling calcium-oxide sorbent for ...
Nonlinear frequency response analysis of forced periodic operations with simultaneous modulation of two general waveform inputs with applications on adiabatic CSTR with square-wave modulations
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Nonlinear frequency response (NFR) method was used to evaluate the forced periodic operations and their potential for improving the system performance compared to steady-state operations. The NFR method was used to evaluate ...
Influence of fluid-mechanical parameters on volumetric mass transfer coefficient in a spout-fluid bed with a draft tube
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In order to apply a spout-fluid bed reactor with a draft tube for the nitrification process of wastewater treatment, the influence of fluid-mechanical parameters on volumetric mass transfer coefficient was analyzed. ...
