Research  |  Core areas of EGICHEM group
Ion Exchange

Egichem research on ion exchange has covered the issue of water pollutant removal through modeling and measurement of heavy metals removal from water solutions with the aid of titanosilicate materials.

Oligomerization

Catalytic reaction has been addressed by Egichem researchers through the synthesis and characterization of catalysts for applications such as the oligomerization of light alcenes to diesel.

Molecular Dynamics

Computation of diffusion properties for new molecules has been studied by Egichem researchers using molecular dynamics approach.

Membranes

Egichem contribute to membranes field has been achieved through the conjugation of synthesis, structural characterization, measurement of permeances and modeling of new inorganic membranes.

Transport Properties

Egichem research covers transport properties through the measurement and modelling of diffusion coefficients. Some of the best models currently found in literature for correlation and prevision of diffusion coefficientes were published by Egichem researchers.

Supercritical Fluid Extraction

Egichem has been working with supercritical fluid extraction technology within the scope of biorefinery, where biomass residues are characterized and extracted aiming at their valorization. This research areas also involves modeling, simulation, scale-up and economic evaluation studies.

Modeling and Simulation

EgiChem possesses solid competencies on modeling and simulation. Comprehensive modeling of equilibra and mass transport phenomena are two important examples, individually or incorporated in specific separation technologies mainly supported by Matlab software. Simulation and optimization of case-study or real industrial processes has also been done with resort to Aspen One software.

Synthesis and characterization of lanthanide titanosilicates

Egichem collaborates on the synthesis and characterization of lanthanide silicates for applications in ion exchange and sensing studies. The main purpose is to take advantage of their photoluminescent properties together with its microporous frameworks, to sense Cesium ion in aqueous solutions. The materials science part of the work is supervised by Professor João Rocha.

Extraction and characterization of vegetable biomass

EgiChem team has skills on studying vegetable biomass from the very first steps of obtaining an extract and performing its characterization. Analytical techniques such as GC-MS and HPLC can be employed for this purpose, and the closeness to agroforestry chemistry partners is an advantage.

Adsorption-Desorption cycles

Egichem models and simulates the four steps of the cyclic adsorption-desorption process (isobaric adsorption, isosteric heating, isobaric desorption, isosteric cooling), in order to evaluate the behaviour of the systems (in terms of temperature, pressure, adsorbed concentration) and optimize the heating or cooling performance.
