1. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts
Abstract : Hydrodemetallization (HDM) is an indispensable step in industrial catalytic hydroprocessing of residual oils. To develop improved HDM catalysts and reactors, a detailed knowledge of the reaction mechanisms and kinetics, and a good understanding of the mechanisms and process of the catalyst decaying are very important.

2. Kraft lignin valorization by hydrotreatment over Mo-based sulfided catalysts
Abstract : The production of green fuels and chemicals from bio-based feedstock can suppress the dependency on fossil resources and help mitigate global climate challenges. Kraft lignin is a thermochemically modified natural lignin obtained from the pulping process as a byproduct. READ MORE

3. Slurry Hydrotreatment of Biomass Materials over Metal Sulfide-based Supported and Unsupported Catalysts
Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks are abundant, carbon-rich, and renewable bioresources that can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE
