Pre-requisites: CHEM2015 AND CHEM2016
Aims and Objectives
Having successfully completed this module you will be able to:
- Discuss possible methods of reducing CO2 emissions and analyse their respective merits
- Elucidate the nature of catalytic processes and their impact in the context of Green Chemistry (E-factor, atom efficiency, F3 factory).
- Rationalise the availability and utilisation of renewable feedstocks and their influence on energy efficiency and the environment
- Discuss the role of porous architectures in the context of driving selectivity in chemical transformations.
- Discuss how energy and chemical feedstocks can be sustainably sourced from either coal or biomass
- Review the availability of alternate solvents and make informed choices based on Chemistry principles
- Understand the chemistry of nuclear power generation, and extraction of metals
- Assess the likely sustainability of medium and large scale chemical and energy related processes.
- Evaluate the role of CO2 and other greenhouse gases in climate change, and be able to reproduce a simple atmospheric model
