  2. 16. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

    Author : Magnus Marklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. READ MORE

  4. 17. Colloidal synthesis of metal nanoparticles

    Author : Anna Pekkari; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inline quality control; palladium; gold; stabilizers; NO2 reduction; core-shell; colloidal synthesis; copper; reduction kinetics; platinum; nanoparticles; segmented flow; nanocube; flow chemistry;

    Abstract : Metal nanoparticles (NPs) are central in a wide range of industrial areas including catalytic and biomedical applications. Due to their interesting physical properties, the demand of these precious materials is steadily increasing, which has created a need for the development of effective and high-performing NPs.

  6. 19. Entrained flow black liquor gasification : detailed experiments and mathematical modelling

    Author : Per Carlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Black liquor, a by-product from the Kraft pulping process is a highly viscous fluid consisting of approximately 30% water, 30 % alkali salts and 40 % combustible material. The alkali salts originating from the pulp making process need to be recovered in order for the pulp mill to be economical and to satisfy environmental regulation. READ MORE

  7. 20. Monolith Reactors in Three-Phase Processes

    Author : Rolf Edvinsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; desulfurization; methanol synthesis; acetylene hydrogenation; Taylor flow; monolith reactor; three-phase; computational fluid dynamics;

    Abstract : The use of monoliths in chemical processes has been studied with the emphasis on liquid-phase hydrogenations. A monolithic catalyst consists of many narrow, parallel channels with catalytically active species either incorporated into the wall itself or into a layer of a porous oxide deposited on the wall (a washcoat).
