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

    University dissertation from Umeå : Umeå universitet

    Author : Johan Ahlkvist; Jyri-Pekka Mikkola; Riitta Keiski; [2014]
    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.

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

    University dissertation from Umeå : Umeå University

    Author : Mikhail Golets; Jyri-Pekka Mikkola; Evgenii Rebrov; [2014]
    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

  3. 3. Ionic liquids in bio-refining synthesis and applications

    University dissertation from Umeå : Umeå universitet

    Author : John Gräsvik; Jyri-Pekka Mikkola; Bertil Eliasson; Manu Lahtinen; [2013]
    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

  4. 4. Three-dimensional structured carbon foam synthesis and applications

    University dissertation from Umeå : Umeå University

    Author : Ngoc Tung Pham; Jyri-Pekka Mikkola; Krisztian Kordas; William Siljebo; Dmitry Yu. Murzin; [2016]
    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.

  5. 5. Biochemical conversion of biomass to biofuels pretreatment–detoxification–hydrolysis–fermentation

    University dissertation from Umeå : Umeå universitet

    Author : Venkata Prabhakar Soudham; Jyri-Pekka Mikkola; Christer Larsson; Tom Birger Granström; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

    Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE
