Hydrocarbon conversion of long-chain paraffins : Role of metal(Pt, Ru, Ni) &influence of acid sites, structures and textural properties of solid catalysts
(Åbo Akademi, 2019)Hydroisomerization of long-chain hydrocarbons for the production of high quality branched fuel was studied due to their vast availability and product versatility. Most of these long-paraffins are cracked to obtain lower ... -
Hydrodeoxygenation of bio-oil model compounds using alumina, zirconia and carbon supported metal catalysts
(Åbo Akademi, 2018)Bio-oil is an attractive alternative to petroleum oil and important renewable source of energy and chemicals. Through hydrodeoxygenation (HDO) it can be transformed into transportation fuel by removal of oxygen. Because ... -
Hydrodeoxygenation of lignin-derived phenol compound isoeugenol over nickel- and cobalt based catalysts
(Åbo Akademi, 2019)The climate change has increased the need of renewable transportation fuels obtained from lignocellulosic biomass. Due to its high oxygen content and complex structure, catalytic hydrodeoxygenation (HDO) is needed to upgrade ... -
Improvement of heat recovery in the paper industry
(Åbo Akademi, 2018)A significant part of the operational costs at pulp and paper mills come from energy costs of heating. One of the most energy consuming processes is the drying of paper in a paper machine. About 20 – 30 MW steam is used ... -
