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 ...
Project and portfolio cash flow development
(2021)
Efficient cash flow management is vital for the survival and long-term success of every company. The nature of the construction business often forces contractors to work with less internal financing and trust that customer ...
Monomers from vegetable oil feedstock : kinetics, catalysis and thermal risk
(Åbo Akademi University & Institut National des Sciences Appliquées de Rouen, 2021-07-09)
Polyurethanes are among the most important polymers in our everyday life, they are industrially produced via the reaction of polyols and di-isocyanates. This process present multiple severe drawbacks such as high toxicity ...
Methods for Researching the Stratification Phenomena and Parameters Effecting it in a Cavern Thermal Energy Storage
(2021)
At the moment energy companies in Finland have invested in large scale thermal energy storage to improve the efficiency of their district heating systems. This means that energy that would otherwise have beenwastedis saved ...
Production schedule optimization in an animal feed industry
(2021)
This thesis focuses on the optimization of the supply chain for an animal feed plant, including product deliveries and the production schedule. A Capacitated Vehicle Routing Planning (CVRP) model has been developed to ...
Alkali chloride induced superheater corrosion – Impact of percentage of molten phase
(2021)
World energy consumption has doubled in the last thirty years, and projections indicate that the energy demand will increase. Carbon dioxide is the most critical greenhouse gas generated by human activity, originating ...
Investigation of waste heat sources and their utilization in process industry
(2021)
Waste heat is a commonly used term for such heat energy that is not utilized in the process but dissipates to the environment unused. Waste heat is a by-product which can be found in various streams exiting ...
Machine learning for predicting alkali salt induced high-temperature corrosion of superheater materials
(2021)
Climate change due to human activities has caused a global desire to lower CO2 emissions in the hope of halting the increasing global temperature. For electricity generation, this means reducing the CO2 emissions by ...
Measurement of electrostatic forces for in-line quality control of ceramic slip
(2021)
In this master’s thesis, done in collaboration with Geberit in Ekenäs, the goal was to determine whether a new in-line measurement probe was suitable for monitoring and controlling the slip manufacturing process. The ...
The potential of lignin as a maritime biofuel
(2021)
In the 1940s, efforts towards lignin valorisation were triggered by high oil prices, but today, the motives are much more varied. The movement towards a greener future to combat climate change and the expected introduction ...
