  2. 1. Study of Catalyst Deactivation in Three Different Industrial Processes

    Author : Ann-Charlotte Larsson; Mehri Sanati; Ferruccio Trifiro; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deactivation; catalyst; SCR; VOC; steam reforming; aerosol particle; potassium; zinc; ash salts; biomass; organosilicon; Chemical engineering; Kemiteknik; Kemi; Chemistry;

    Abstract : Deactivation of catalysts were investigated focusing on three industrial processes: 1) Selective Catalytic Reduction (SCR) for abatement of NOx from biomass combustion using V2O5-WO3 /TiO2 catalysts; 2) Catalytic oxidation of volatile organic compounds (VOC) from printing industries using a Pt/γ-Al2O3 catalyst; and 3) Ni and Pt/Rh catalysts used in steam reforming reaction of bio-syngas obtained from biomass gasification.The aim has been to simulate industrial conditions in laboratory experiments in order to comprehend influence of compounds affecting catalysts performance.

  4. 2. Biomass Pre-treatment for the Production of Sustainable Energy : Emissions and Self-ignition

    Author : Katarina Rupar-Gadd; Mehri Sanati; Evert Ljungström; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terpenes; SPME; biomass; pellets; self-ignition; storage; drying; calorimetry; Chemical engineering; Kemiteknik; Bioteknik; Biotechnology;

    Abstract : Organic emissions with focus on terpenes, from biomass drying and storage were investigated by Solid Phase Microextraction (SPME) and GC-FID and GC-MS. The remaining terpenes in the biomass (Spruce and pine wood chips) after drying were dependant on the drying temperature and drying medium used. READ MORE

  5. 3. The Survey of Ash Agglomeration Phenomena in a Commercial Circulating Fluidised Bed (CFB)

    Author : Ann Charlotte Tranvik; Mehri Sanati; Britt-Marie Steenari; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; combustion; biomass; agglomeration; ash; silicate; potassium; bed material; layer; deposition; Thermal energy engineering; Termisk energiteknik;

    Abstract : Renewable energy sources will act an important roll in the development of sustainability in the future in order to protect environment and ecological cycle.Amongst the Kyoto protocol conclusions there is an agreements for the EU a reduction of 8 % of greenhouse gas emissions (corresponding of around 6 million tonnes of CO2 equivalents ) between 2008-2012 (compared to 1990 level).
