  1. 1. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Samina Gulshan; [2019]
    Keywords : ;

    Abstract : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. READ MORE

  2. 2. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

    University essay from KTH/Materialvetenskap

    Author : Febryana Nugrahany; [2018]
    Keywords : ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

    Abstract : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. READ MORE

  3. 3. Process Design and Technical feasibility analysis of Catalytic fas tpyrolysis for biocrude production

    University essay from KTH/Materialvetenskap

    Author : Jonathan Guzman; [2018]
    Keywords : ;

    Abstract : The demand of renewable fuels is increasing. Catalytic Fast Pyrolysis is a growing technology that could supply with high quality bio crude that can be used in the already existing infrastructure. The process of choice in this paper to implement this technology is insitu circulating fluidized bed using saw dust as feed. READ MORE

  4. 4. Simulation of a lab-scale methanation reactor

    University essay from KTH/Kemiteknik

    Author : Seyedeh Guilnaz Mirmoshtaghi; [2011]
    Keywords : Biogas; methanation reactor; Ruthenium catalyst; isothermal; adiabatic;

    Abstract : By the everyday increasing enthusiasm for using renewable-sustainable sources in energy production area, focusing on one and optimizing it in the best possible way should be of much interest.Biogas production from anaerobic digestion of wastes is a well known energy source which could be applied more efficiently if the CO2portion of it would be upgraded to CH4as well.

  5. 5. Application of the ChlorOut concept in a waste wood fired CFB boiler

    University essay from SLU/Dept. of Energy and Technology

    Author : Mårten Carlberg; [2008]
    Keywords : superheater; corrosion; alkali; chlorides; ammonium; sulphate; chlorOut; IACM; potassium; KCl; bio fuels; sulphur;

    Abstract : Boilers converting from sulphur rich fossil fuels to alkali and chlorine rich bio fuels often experience an increased super heater corrosion. This is partly due to the increased formation of KCl during combustion of bio fuels. The problem could, for instance, be handled with a sulphur containing additive to the fuel or to the flue gases.
