  1. 6. Numerical Modelling of Wood Pyrolysis

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Marc Mate; [2016]
    Keywords : biomass; gasification; renewable energy; sustainability; heat transfer; reaction engineering;

    Abstract : In this project, a numerical model describing the reaction mechanism and the mass and energy transport in wood pyrolysis is studied. The applicability of the model in predicting actual biomass pyrolysis assessed by comparing the model to TGA experimental measurements. READ MORE

  3. 7. Thermogravimetric analysis and modeling of pyrolysis of macroscopic wood particles

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : YOSRA PERSNIA; [2016]
    Keywords : Biomass; gasification; renewable energy; thermogravimetric analysis; mathematical modeling;

    Abstract : The knowledge of kinetics of pyrolysis is important. It is also challenging to find parameters for kinetic which can be applied at different sizes of biomass. Many researchers have been investigating the pyrolysis behavior of wood powders due to heat and mass transfer limitations. READ MORE

  4. 8. Waste-to-Energy : A study on Reaction Kinetics of Tropical Wood Sawdust

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bertrand Asongwe Tita; [2016]
    Keywords : Tropical biomass; Thermo-gravimetric Analysis TGA ; reaction kinetics; pyrolysis;

    Abstract : The reaction kinetics of Iroko and Mahogany were studied using TGA. The pyrolysis process was achieved using six different heating rates of 2,5,8,12,15 and 20˚C. A 15˚C/min heating rate was used for gasification in steam at different temperatures while varying the concentrations of nitrogen and steam in the process. READ MORE

  5. 9. Simultaneous detection of potassium, water vapor and temperature with tunable diode laser absorption spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Edvin Norén; [2015]
    Keywords : TDLAS; DAS; WMS; Simultaneous detection; Measurement; Potassium; Water vapor; Temperature; Biomass; Optics;

    Abstract : Existing tunable diode laser absorption spectroscopy (TDLAS) sensors for potassium (K) and for water vapor (H2O) and temperature were combined to enable simultaneous measurements in combustion and gasification processes. In-situ real-time detection of the above mentioned combustion parameters will improve the understanding of ash-formation during thermochemical conversion of biomass. READ MORE

  6. 10. Investigation of the Effects of Introducing Hydrodynamic Parameters into a Kinetic Biomass Gasification Model for a Bubbling Fluidized Bed

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Daniel Andersson; Martin Karlsson; [2014]
    Keywords : Gasification; Gasifier; Biomass; Bubbling fluidized beds; Reaction kinetics;

    Abstract : Biomass is an alternative to fossil fuels that has a lower impact on the environment and is thus of great interest to replace fossil fuels for energy production. There are several technologies to convert the stored energy in biomass into useful energy and this thesis focuses on the process of gasification. READ MORE
