  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.

  3. 7. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2018]
    Keywords : Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Abstract : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. READ MORE

  4. 8. 2-Hydroxypyridine-Ligated Pd-complexes as pre-catalysts in Hydrogen Borrowing Chemistry α -Alkylation of Ketones Using Alcohols

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ayesha Kanwal; [2017]
    Keywords : Hydrogen Borrowing in activation of alcohols; Palladium in Catalysis; hydrogenation and dehydrogenation reactions; hydrogen borrowing concept for hydrogenation and dehydrogenation reactions; 2-hydroxyquinoline Ligand; 2-hydroxy pyridine ligands; inorganic chemistry; oorganisk kemi; Chemistry;

    Abstract : An efficient method for selective alpha-alkylation of ketones with alcohols was developed using 2-hydroxypyridine-based ligands coordinated by palladium as pre-catalysts. The reactions were performed without additional additives under mild reaction conditions. The method is environmentally friendly to build C-C bond as water is the only byproduct. READ MORE

  6. 10. Olfactory discrimination performance and longterm odor memory in Asian elephants (Elephas maximus)

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Alisa Rizvanovic; [2012]
    Keywords : Asian elephant; Elephas maximus; Behavioral testing; Olfactory discrimination; Olfactory memory;

    Abstract : Behavioral evidence suggests that Asian elephants strongly rely on their sense of smell in a variety of contexts including foraging and social communication. Using a food-rewarded two-alternative operant conditioning procedure, three female Asian elephants were tested on their olfactory discrimination ability with 1-aliphatic alcohols, n-aldehydes, 2-ketones, n-carboxylic acids and with a set of twelve enantiomeric odor pairs.
