1. 11. Waste-integrated biorefineries : A path towards efficient utilization of waste

   Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. LÄS MER

3. 12. Waste Heat Recovery from Combustion Engines based on the Rankine Cycle

   Författare :Gunnar Latz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste heat recovery; Rankine cycle; piston expander;

   Sammanfattning : Most of the energy in the fuel burned in modern automotive internal combustion engines is lost as wasteheat without contributing to the vehicle’s propulsion. In principle some of this lost energy could becaptured and used to increase the vehicle’s fuel efficiency by fitting a waste heat recovery system to theengine. LÄS MER

4. 13. Waste-Heat Recovery from Combustion Engines based on the Rankine Cycle

   Författare :Gunnar Latz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rankine cycle; waste heat recovery; energy losses; energy efficiency; vehicle propulsion;

   Sammanfattning : The majority of the energy in the fuel burned by the combustion engines used in modern vehicles is lost in the form of waste heat and does not contribute to the propulsion of the vehicle. Three different technologies have been proposed for recovering some of this lost heat and thereby increasing the overall efficiency of combustion engines: the turbocompound, thermoelectric converters, and heat engines based on the Rankine cycle.

5. 14. Improving Model-Based Systems Analysis of Waste Management

   Författare :Mattias Olofsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material recycling; modelling; import; energy recovery; greenhouse gas emissions; export; systems analysis; scrap markets; waste prevention; waste management;

   Sammanfattning : Model-based systems analysis is a tool to support decision-makers in the field of waste management. Of special concern in this thesis is the development of mathematical models for the analysis of the technological system. The aim of the models (here denoted WMS models) is to address whole waste management systems, i.e. LÄS MER

7. 15. Nano-EngineeredThermoelectric Materials for Waste Heat Recovery

   Författare :Mohsin Saleemi; Muhammet Toprak; Mari-Ann Einarsrud; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Energy crisis and thermal management related issues have been highlighted in the modern century due to escalating demands for energy consumption and global warming from fossil fuels. Sustainable and alternative energy sources are an ever growing global concern. LÄS MER
