Transformation of carbon dioxide to diethyl carbonate over ceria and ceria-supported catalysts
(Åbo Akademi - Åbo Akademi University, 2015-05-08)
Carbon dioxide is regarded, nowadays, as a primary anthropogenic greenhouse gas leading to global warming. Hence, chemical fixation of CO2 has attracted much attention as a possible way to manufacture useful chemicals. One ...
The role of metal ions in selective and sustainable processes
(Åbo Akademi - Åbo Akademi University, 2015-10-14)
Sustainability and recycling are core values in today’s industrial operations. New materials, products and processes need to be designed in such a way as to consume fewer of the diminishing resources we have available ...
Hydrogenation of L-arabinose, D-galactose, D-maltose and L-rhamnose
(Åbo Akademi - Åbo Akademi University, 2012-05-04)
Towards novel biogas upgrading processes
(Åbo Akademi - Åbo Akademi University, 2013-03-26)
Biogas production has considerable development possibilities not only in Finland but all over the world since it is the easiest way of creating value out of various waste fractions and represents an alternative source of ...
Methyl and ethyl chloride synthesis in microreactors
(Åbo Akademi - Åbo Akademi University, 2014-09-19)
Methyl chloride is an important chemical intermediate with a variety of applications. It is produced today in large units and shipped to the endusers. Most of the derived products are harmless, as silicones, butyl rubber ...
Heterogeneous catalytic copolymerization reactions of carbon dioxide and propylene oxide over polyalcohols under subcritical conditions
(Åbo Akademi University and Universidad de Valladolid, Spain, 2017-03-15)
Carbon dioxide (CO2) is one of the main gases which cause the greenhouse effect. As a way to attenuate this damage, CO2 could be used as a building block for copolymerization reactions; precisely as C1 feedstock (monomer ...

Reactor Modelling for Fluid-Solid Systems
(Åbo Akademi - Åbo Akademi University, 2017-10-13)
Reactor Modelling for Fluid-Solid Systems
The aim of the present doctoral thesis is the development of reliable mathematical models for the simulation of fluid-solid reactors. The main idea was to elaborate a rigorous ...
?-Pinene oxide and verbenol oxide isomerizations over heterogeneous catalysts
(Åbo Akademi - Åbo Akademi University, 2014-12-19)
Terpenes are a valuable natural resource for the production of fine chemicals. Turpentine, obtained from biomass and also as a side product of softwood industry, is rich in monoterpenes such as α-pinene and β-pinene, which ...
Fractionation of marine algae to its constituents towards valuable chemicals and energy products
(Åbo Akademi - Åbo Akademi University, 2017-11-20)
There is an urgency for finding renewable resources for the replacement of fossil resources aiming at more environmentally friendly processing. The old concept of processing forestry biomass for pulp and paper that dominated ...
