  1. 41. Computational framework for studying charge transport in high-voltage gas-insulated systems

    Författare :Shailendra Singh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drift diffusion equation; gaseous dielectrics; high voltage; gas discharge; low temperature plasma; streamer propagation;

    Sammanfattning : Increasing demands in electric energy stimulates a shift in functional requirements to power distribution networks and pushes equipment manufacturers to develop highly optimized products where high rated parameters (e.g., energy, voltages) are combined with reduced geometrical dimensions of components.

  3. 42. Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading

    Författare :Helena Svensson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuels; Reverse-flow reforming; Gas upgrading; Amine absorption;

    Sammanfattning : Replacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. LÄS MER
