  1. 11. The effect of a feruloyl esterase producing inoculant along with mechanical treatment prior to ensiling on fibre digestibility of grass silage

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Kiros Kelkay Haile; [2019]
    Keywords : ryegrass; in vitro incubation; feruloyl esterase; ensiling; meadow fescue; fibre digestibility;

    Abstract : Plant fibre is the main portion of dairy cattle diets. It is also important in maintaining health and proper function of the rumen. However, digestibility of fibre is relatively low, and, in most cases, it is not more than 60%. In cell walls of grasses and cereals, lignin and hemicellulose are connected, forming a matrix.

  3. 12. Influence of metal ions on lignin-based carbon fiber quality

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Sofia Andersson; [2017]
    Keywords : Carbon fiber; lignin; kraft lignin; cellulose; impregnation; LignoBoost; metal; ash; inorganic; black liquor; morfology; tensile testing; dry-jet wet spinning;

    Abstract : Carbon fiber is a lightweight, versatile material with many current and potential applications. To be able to expand the market for carbon fiber composites in other areas than special applications the production costs must be reduced. READ MORE

  4. 13. Evaluation of thermal and mechanical properties of the composite material of LignoBoost- lignin and recycled polyurethan : A preliminary feasibility study for a novel composite material from waste materials

    University essay from Karlstads universitet

    Author : Shaymaa Al-Taee; [2017]
    Keywords : ;

    Abstract : The purpose of this study was to investigate the possibility of producing a composite material of lignoBoost- lignin and recycled polyurethane. Also, the study evaluated the thermal and mechanical properties of the composite materials. READ MORE

  5. 14. Development of characterization methods for lignocellulosic biogas substrates

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Mirjam Victorin; [2016]
    Keywords : characterization methods; anaerobic digestion; straw; Biogas; lignocellulose; BMP; mechanical pretreatment; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : As the need of environmentally friendly alternatives to fossil fuels is growing bigger, so is the need for knowledge and research around possible new raw materials that could serve that pur-pose. One discussed product is biogas. READ MORE

  6. 15. Evaluation of the Carbonization of Thermo-Stabilized Lignin Fibers into Carbon Fibers

    University essay from Linköpings universitet/Kemi; Linköpings universitet/Tekniska fakulteten

    Author : Henrik Kleinhans; [2015]
    Keywords : Lignin; Carbon Fibers; Carbonization; Stabilization; Uniaxial Tensile Testing; Thermomechanical Analysis TMA ; Thermogravimetric Analysis TGA ; Fourier Transform Infrared Spectroscopy FTIR ; Scanning Electron Microscope SEM ; Energy Dispersive X-ray Spectrometer EDS ;

    Abstract : Thermo-stabilized lignin fibers from pH-fractionated softwood kraft lignin were carbonized to various temperatures during thermomechanical analysis (TMA) under static and increasing load and different rates of heating. The aim was to optimize the carbonization process to obtain suitable carbon fiber material with good mechanical strength potential (high tensile strength and high E-modulus). READ MORE
