  1. 1. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Author : Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Abstract : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. READ MORE

    Author : Viviane Forsberg; Håkan Olin; Renyun Zhang; Magnus Hummelgård; Joakim Bäckström; Li Yang; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; MoS2; Exfoliation; Inkjet Printing; 2D materials; Environmental Friendly; TMD; thin films; industrial printing; 2D inks; printed electronics; thin films carrier mobility; large-area electronics; graphene analogues; solar cells;

    Abstract : Since the discovery of graphene, substantial effort has been put toward the synthesis and production of 2D materials. Developing scalable methods for the production of high-quality exfoliated nanosheets has proved a significant challenge. READ MORE

  3. 3. Hydrotreatment of lignin and its bio-oils over transition metal sulfide-based supported and unsupported catalysts

    Author : You Wayne Cheah; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Hydrotreatment; MoS2; Bio-oils; Transition metals; Pyrolysis oil; Propylguaiacol; Reaction network; Unsupported TMS; Advanced biofuels; Kraft lignin;

    Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks such as lignin can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE

  4. 4. Catalytic Upgrading of Waste Oils to Advanced Biofuels – Deactivation and Kinetic Modelling Study

    Author : Prakhar Arora; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Stearic acid; TEM; Advanced biofuels; NiMo; Catalytic HDO; MoS2; Kinetic modelling; Oleic acid; Hydrodeoxygenation;

    Abstract : The demand for liquid hydrocarbons as transportation fuels is enormous and ever growing. Advanced biofuels is one of the promising solutions to keep pace with the global transition to cleaner energy by reducing greenhouse gas emissions from the transport sector. READ MORE

  5. 5. Spin Transport in Two-Dimensional Material Heterostructures

    Author : André Dankert; Chalmers University of Technology; []
    Keywords : Black phosphorous; Topological insulator; h-BN; Silicon; Transistor; Spintronic; MoS2; Graphene; 2D materials; Spin polarized tunnelling; Schottky barrier;

    Abstract : Spintronics is considered as an alternative for information processing beyond the charge based technology. The spintronic device performance depend on the spin relaxation mechanisms in the channel material. Si and graphene are interesting for their long spin coherence lengths and ideal for spin transport channels. READ MORE
