  2. 6. Molecular Simulations of Microstructure, Thermodynamics, and Dynamics of Complex Liquid Mixtures at Interfaces and Confined Spaces

    Author : Qingwei Gao; Ji Xiaoyan; Sture Nordholm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : In modern chemical engineering, process intensification is realised by introducing a nano- or micro-interface. The introduction of such an interface breaks the homogeneous nature of the fluid and forms a unique nano- or micro-interfacial structure, which has a significant impact on the properties of fluids.

  4. 7. CO2 electrochemical reduction: Techno-economic evaluation and experimental research for producing methanol

    Author : Fangfang Li; Xiaoyan Ji; Joakim Lundgren; Klas Engvall; Hailong Li; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Recently, CO2 electrochemical reduction (CO2R) has gained popularity, to cope with the strict environmental rules on greenhouse gas emissions, and to convert CO2 to value-added chemicals/fuels. Ionic liquids (ILs) have been considered as potential media for CO2R owing to their multi-functions in enhancing CO2R solubility and improving CO2R reaction rate and product selectivity. READ MORE
