  2. 1. Formic and Levulinic Acid from Cellulose via Heterogeneous Catalysis

    Author : Johan Ahlkvist; Jyri-Pekka Mikkola; Riitta Keiski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Levulinic acid; formic acid; Amberlyst 70;

    Abstract : The chemical industry of today is under increased pressure to develop novel green materials, bio-fuels as well as sustainable chemicals for the chemical industry. Indeed, the endeavour is to move towards more eco-friendly cost efficient production processes and technologies and chemical transformation of renewables has a central role considering the future sustainable supply of chemicals and energy needed for societies.

  4. 2. Development of nitrogen-containing materials for capture and catalytic conversion of carbon dioxide to value-added chemicals

    Author : Thai Q. Bui; Jyri-Pekka Mikkola; Knut Irgum; William Siljebo; Riitta Keiski; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCUS; PEHA; DBU; mesoporous melamine-formaldehyde; DMC; cyclic carbonate; flow reactor; Physical Chemistry; fysikalisk kemi; sustainable development; hållbar utveckling;

    Abstract : Anthropogenic carbon dioxide (CO2) emissions have become a critical environmental issue because a large amount of CO2 releasing into the atmosphere, particularly from the massive use of fossil fuels, is the major factor promoting the global warming and climate change. To mitigate the CO2 emissions, Carbon Capture, Utilization and Storage (CCUS) can be one of important solutions. READ MORE

  5. 3. Heterogeneously Catalyzed Valorization of Monoterpenes to High Value-Added Chemicals

    Author : Mikhail Golets; Jyri-Pekka Mikkola; Evgenii Rebrov; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalysis; terpenes; alpha-pinene;

    Abstract : A potential industrial process is profitable only if it is successfully implemented by the continuously developing chemical industry. Throughout last decades heterogeneous catalysis has opened doors to the creation of various know-how products which previously were considered unfeasible. READ MORE

  6. 4. Ionic liquids in bio-refining : synthesis and applications

    Author : John Gräsvik; Jyri-Pekka Mikkola; Bertil Eliasson; Manu Lahtinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid; Joniska vätskor;

    Abstract : Fossil fuel resources are not limitless so alternative renewable recourses are needed to fill the void that inevitably will be created once the supplies of this resource start do dwindle. Biomass has the potential to fill this void. READ MORE

  7. 5. Three-dimensional structured carbon foam : synthesis and applications

    Author : Ngoc Tung Pham; Jyri-Pekka Mikkola; Krisztian Kordas; William Siljebo; Dmitry Yu. Murzin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon foam; melamine foam; absorbent; water purification; heterogeneous catalyst; catalyst support; SpinChem®; rotating bed reactor; water electrolysis; energy conversion;

    Abstract : Recently, due to the unique properties and structures such as large geometric surface area, electrical conductivity and light weight, 3D structured carbon materials have been attracting extensive attention from scientists. Moreover, the materials, which can provide well-defined pathways for reactants to easily access active sites, are extremely useful for energy conversion as well as environmental and catalysis applications.
