  1. 1. Coke characterization on HZSM-5, Fe/ZSM-5, Ni/ZSM-5, and Fe-Ni/ZSM-5 from Catalytic Fast Pyrolysis of Biomass

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Isa Duman; [2018]
    Keywords : Biomass; Bio-Oil; Catalytic Fast Pyrolysis; Coke; ZSM-5; Biomassa; Bio-Olja; Katalytisk Pyrolys; Koks; ZSM-5;

    Abstract : The combustion of fossil fuels has for a long time been a problem from an environmental and sustainability point of view, especially when it comes to the emissions of atmospheric carbon dioxide. The environmental concern has for instance shifted the attention towards finding new sustainable alternatives for producing chemicals and fuels, as a substitute to today’s dependence on fossil based crude oil.

  5. 4. Toward libraries for increased bio plastic production in cyanobacteria

    University essay from KTH/Skolan för bioteknologi (BIO)

    Author : Mahanand Muppidi; [2014]
    Keywords : cyanobacteria; metagenomics; libraries; bioplastic; transcription factors;

    Abstract : Cyanobateria are promising cell factories due to their minimal nutrient requirements and utilization of asmospheric carbon di-oxide as its sole carbon source. In particular, polyhydroxybutyrate (PHB) is an industrially useful bio plastic that is produced naturally by some cyanobacteria. READ MORE

  6. 5. Emissions of biogenic volatile organic compounds in a Salix biofuel plantation : field study in Grästorp (Sweden)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Broberg; [2013]
    Keywords : Salix; biogenic volatile organic compounds; BVOC; willow; atmosphere; soil; physical geography; Earth and Environmental Sciences;

    Abstract : Biogenic volatile organic compounds (BVOCs) play an important role in the climate system by altering the oxidative capacity of the atmosphere, affecting the lifetime of methane and production of tropospheric ozone, and by contributing to formation of aerosols and clouds. Salix plants (willows) are well-documented emitters of BVOCs and this study aims to examine emissions in a Salix biofuel plantation for a better understanding of its total climate impact. READ MORE
