Research fellow, Aalto University, Finland

- Conducting experiments to analyze several environmentally friendly catalysts (such as Tertiary amines) in reducing the retention time and material consumption in oxidation of Lignin and HexA as two major undesired compounds in pulps.

- Experimental analysis and characterization of brightness stability, organically-bond compound, Carbonyl group content in catalytically treated pulp samples.

- Optimization of a complete pulp bleaching process in order to gain the shortest overall reaction time, by manipulating the pH, material consumption, catalyst, time duration of each chemical applied, and chemical order processes.

- Setting up a small scale experiment to predict a large scale behavior of different types of catalyst in oxidation of Carbon-Carbon double-bond compounds under various experimental conditions, i.e., pH, material, and time to investigate the decomposition mechanisms.

- Design and implementation of a high consistency reactor for Ozone oxidation measurement analysis.

- Implementation of a low and medium consistency reactor for oxidation of organic compound such as Lignin and HexA.
