Studies on selective removal of volatile organosulfur compounds from model biogas stream using deep eutectic solvents
The scientific aim of the project is to reduce the selective transfer barrier the volatile organosulfur compounds (VSCs) from the model biogas stream, thus accreting the VSCs absorption effectiveness by enhancing the accessibility of the active sites in on deep eutectic solvents (DES).
The project will be investigated the effect of the structure of symmetric quaternary salts (alkyl chain length and cation type), and co-existing organic solvents on the VSCs absorption efficiency. For newly synthesized DESs will be specified basic physicochemical properties, i.e. melting point, decomposition temperature, viscosity, density, volatility DES, or solubility of VSCs in DES, which influence efficacy the absorption process. Furthermore, the chemical structure of the new DESs and interaction between DES and VSCs (which influence on the selective "capture" of VSCs from the biogas stream) will be determined using molecular modeling (density functional theory (DFT) simulations, electrostatic potentials (ESP), reduced density gradients (RDG) analysis), and using spectroscopic methods (Nuclear Magnetic Resonance (NMR) spectroscopy and Fourier Transform Infrared spectroscopy (FT-IR)). Additionally, in the project, the studies on the regeneration of new absorption materials will be prepared.
A research hypothesis is assumed that the results of investigations planned in this project will examine and identify the main mechanism removal of selected VSCs compounds from model biogas stream with used DES in the absorption process.

Monitoring of absorptive model biogas purification process using sensor matrices and gas chromatography
PublicationThis study examined the process of purifying model biogas using a new type of absorbent based on a Deep Eutectic Solvent (DES) and a commercially available absorbent (Genosorb) to remove acetone, toluene, and cyclohexane. The main aim of the research was to control the purification efficiency using gas chromatography (GC) and an alternative method based on sensor matrices (SM). As a result of comparing the multidimensional SM signals...
