  1. 1. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Melker Axelsson; [2023]
    Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

  3. 2. Valence Band Properties of the Ruthenium Complex Catalyst Using Ab Initio Theory

    Abstract : Ruthenium complexes has been geometrically optimized with different combinations of basis sets. Using single point calculation, the Density of States and partial Density of States has been calculated. RuIII-OH2 experienced a shift towards higher binding energies. READ MORE

  4. 3. Synthesis of Ruthenium-based Water Oxidation Catalysts and Mechanistic Study

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : YOSHIDA MOTOKI; [2015]
    Keywords : Ruthenium Complex; Water Oxidation Catalyst; Electrochemistry; Oxygen Evolution; Pourbaix Diagram;

    Abstract : Two series of new mononuclear ruthenium complexes with hydrophobic or hydrophilic ligands [Ru(bda)L2] and [Ru(pdc)L3] (H2bda = 2,2'-bipyridine-6,6'-dicarboxylic acid; H2pdc = 2,6-pyridinedicarboxylic acid; L = pyridyl ligands) were synthesized and their electrochemical properties and catalytic activity toward water oxidation were examined. It was revealed that the hydrophobic ligands introduced to [Ru(bda)L2 ] improved the catalytic performance, ahnost twofold TON and TOF values were achieved compared to the [Ru(bda)] catalyst with hydrophilic ligands.

  5. 4. Simulation of a lab-scale methanation reactor

    University essay from KTH/Kemiteknik

    Author : Seyedeh Guilnaz Mirmoshtaghi; [2011]
    Keywords : Biogas; methanation reactor; Ruthenium catalyst; isothermal; adiabatic;

    Abstract : By the everyday increasing enthusiasm for using renewable-sustainable sources in energy production area, focusing on one and optimizing it in the best possible way should be of much interest. Biogas production from anaerobic digestion of wastes is a well known energy source which could be applied more efficiently if the CO2portion of it would be upgraded to CH4as well. READ MORE
