21. Production of Hydrogen for Oil Refining by Thermal Gasification of Biomass: Process Design, Integration and Evaluation
Abstract : Hydrogen is an important part of crude oil refining operations since it is required in several units for the desulphurization and upgrading of various oil fractions. At present, most of the refineries meet their hydrogen demand through methane steam reforming, a refinery unit that can represent up to 25% of the plant’s fossil CO2 emissions. READ MORE

23. Mechanism of the passive NOx adsorption process on zeolite-supported Pd in controlling cold-start emissions
Abstract : Passive NOx adsorbers (PNA) have been used for preventing NOx emissions being released during a cold start. This method involves trapping NOx on an adsorbent at low temperatures and releasing them later, when the exhaust temperature exceeds 200℃. READ MORE

24. Design, Synthesis and Evaluation of Photoswitches for Molecular Solar Thermal Energy Storage Systems
Abstract : To meet the future energy demands and handle climate changes, new sustainable energy sources must be developed. Over the last decades, great scientific progress on harvesting solar energy has been made, but storing the energy is still a challenge. READ MORE

25. Low temperature deicing of road infrastructure using renewable energy
Abstract : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.
