  1. 6. 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.

  4. 8. Parameter setting on catalytic controller : Using Design of Experiments and Scanning Electron Microscope Analysis

    University essay from Högskolan i Jönköping/JTH, Produktutveckling

    Author : Unnikrishnan Asan Janardhanan Pillai; Dharani Shanmugavel; [2017]
    Keywords : Design of Experiments; Catalytic converter; Catalyst deactivation; Engine emission control; Scanning Electron Microscope;

    Abstract : This thesis work has been conducted in the Handheld Laboratory at Husqvarna AB with the purpose of finding the parameters responsible for the performance of the catalytic converters used in the test rig. The catalytic converters are used in the test rig during the long term testing of the chain saws to reduce the hydrocarbon content from the exhaust before it enters into the environment. READ MORE

  5. 9. Evaluation of Non-Noble Metal Catalysts for CO Oxidation

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Daniel Jonsson; [2016]
    Keywords : CO oxidation; sulfur; deactivation; catalysis; CuO;

    Abstract : The aim of the study is to evaluate the ability of non-noble metal catalysts to function as the commercially used noble metal catalyst. The exhaust gas that was used in the project is generated from a heater developed by ReformTech AB with diesel as fuel. The compound that was focused on is carbon monoxide that has a concentration of 300-750 ppm. READ MORE

  6. 10. Preparation and evaluation of sulfided NiMo/γ-Al2O3 hydrotreating catalysts

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : ALI KAMYAB; [2016]
    Keywords : NiMo catalyst; hydrotreating; phosphorous; catalysis; preparation;

    Abstract :   Four nickel-molybdenum catalysts were synthesized on gamma alumina with higher surface area and on NiMo catalyst was prepared using gamma alumina with lower surface area. Catalysts with higher-surface-area support were prepared by co-impregnation, sequential impregnation and adding phosphorous. Theses catalysts were calcined at 500  ͦC. READ MORE
