Abstract:

In the global warming scenario, a literature review on carbon dioxide capture technologies shows that CO2 capture by chemical absorption seems to be the immediately viable route for sustainable energy supply in near future. The technology for chemical absorption is available and has been practiced in the industry. Development and identification of optimal absorbents for absorption is required to employ it on the scale required for CO2 capture and to minimize the energy penalty of capture. Hydroxide and carbonate systems have been used for absorption of CO2 from the beginning of the 20th centur

Abstract:

Coastal areas in Grenada and the Caribbean are experiencing an abundance of stranded macroalgae. Climate change and eutrophication are probable causes of this inconvenience. This leads to logistic and economic dilemmas for the Caribbean societies. Research of methods to benefit from the algal bloom is therefore valuable for a sustainable future in these countries. Studies of biogas and fertilizer production are initiated around the world, but a large scale production is absent. Therefore, this thesis scrutinize the requirements for producing biofertilizer from biogas by examine the content of

Ever increasing anthropogenic emissions of greenhouse gas carbon dioxide (CO₂) are considered as the main driving force behind climate change on Earth. Despite the incentives surrounding carbon-free energy, it will take decades until significant market penetration is achieved. In the meantime, while carboneous fossilized energy sources continue to dominate the energy blend and worldwide energy demand is continuously increasing, carbon capture and storage (CCS) can offer an immediate solution to fight climate change.

l,2-Dioxines are an important class of compounds that are useful in organic synthesis for the incorporation of 1,4-oxygen functionality. 1,2-Dioxines contain a weak peroxide bond that may be readily reduced and which may also undergo transition metal mediated homolysis yielding reactive cis-γ-hydroxyenone intermediates. These cis-γ-hydroxyenone intermediates undergo cyclopropanation when allowed to react with stabilised phosphorus ylides. The synthesis of some l,2-dioxines is presented. This is followed by an investigation into the cobalt catalysed rearrangement of unsymmetrical 1,2-dioxines
