  1. 1. DME and the Heavy Duty Diesel Engine

    Author : Henrik Salsing; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; diesel engine; Dimethyl Ether; fuel injection system; DME;

    Abstract : Increasing awareness of adverse anthropogenic environmental effects, such as the effectsof combusting fossil fuels on atmospheric carbon dioxide concentrations, and thatcombustion-related emissions from the transportation sector are going to approachsustainable levels in the near future has led to increased interest in fuels from renewablesources. These fuels offer possibilities to diversify the feedstocks that can be used forfuel production, as well as to reduce fossil carbon dioxide emissions, thereby reducingour dependence on a very limited range of sources.

  2. 2. DME Combustion in Heavy Duty Diesel Engines

    Author : Henrik Salsing; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; heavy duty; DME; dimethyl ether; Diesel engine;

    Abstract : Interest in alternative energy and fuels has grown considerably in recent years due to increasing concern about the adverse effects of global warming, the limited sources of non-renewable feedstocks, the insecurity of their supply and associated fluctuations in their prices. However, although there is an urgent, and widely recognized, need to address these issues, selecting suitable candidate feedstocks and fuels is far from straightforward, since numerous factors must be considered when selecting promising candidates for further evaluation and, ultimately, commercial use.

  3. 3. RhPt and Ni based catalysts for fuel reforming in energy conversion

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Angélica Viviana González Arcos; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

    Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE

  4. 4. Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Houman Ojagh; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable diesel; Sulfided phase; Carbon deposition; Poisoning; Hydroconversion; Deactivation; Brønsted acid sites; Ring opening; Hydrodeoxygenation HDO ;

    Abstract : Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies Houman Ojagh Department of Chemistry and Chemical Engineering Chalmers University of Technology Abstract Production of biomass derived fuels such as renewable diesel, are primarily intended to reduce the reliance of the conventional engines on petroleum fuels as well as the emission of CO2 from fossil hydrocarbons. Hydrodeoxygenation (HDO) is a powerful technique that has been regularly used in the fuel upgrading processes. READ MORE

  5. 5. Excess heat utilisation in oil refineries - CCS and algae-based biofuels

    Abstract : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. READ MORE
