    Abstract : In this thesis, a numerical approach is adopted to study biomass thermochemical conversion. Detailed physical and chemical processes involved in the thermochemical conversion of biomass are considered. READ MORE

  5. 8. Benzene-char conversion and particle-vapor characterization in biomass gasification

    Author : Mario Morgalla; Michael Strand; Leteng Lin; Henrik Wiinikka; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; fluidized bed; particulate matter; aerosol; char; tars; benzene conversion.; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. READ MORE

  6. 9. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory

    Author : Xiaolei Zhang; Weihong Yang; Linda J. Broadbelt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass thermal conversion; cellulose pyrolysis; char steam gasification; adsorption; interaction; mechanism; quantum chemistry; density functional theory;

    Abstract : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.

  7. 10. Optical Diagnostics for Quantitative Potassium Chemistry in Biomass Thermochemical Conversion Processes

    Author : Wubin Weng; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; TDLAS; Sulfation; Biomass; UV absorption spectroscopy; TLAF; Potassium chemistry;

    Abstract : Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. READ MORE
