  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.
