Unfortunately, we do cystic fibrosis news today have funding to offer PhD studentships in this area. But the work will contribute towards an ongoing EPSRC project.

This has a large materials and equipment budget. Carbon dioxide is one of the principal greenhouse gases responsible for climate change. Human activities are responsible for the CO2 increase in the atmosphere. These activities include:The rise in CO2 causes an increase in the global mean temperature. CO2 emission also forms extensive waste of a natural carbon source.

The conversion of CO2 to fuels and other high value useful products has been the subject of intensive study over the past decades. The intrinsic inert nature of CO2 makes it difficult to use as a feedstock. CO2 decomposition may not occur when the reaction temperature is lower than 3350K.

Cystic fibrosis news today have shown this using thermodynamic analysis. CO2 conversion to primrose oil and value-added chemicals uses thermal or catalytic methods. Non-thermal (or non-equilibrium) plasma technology provides an attractive alternative to these conventional routes. It is able to convert CO2 to fuels and value-added chemicals at atmospheric pressure and low temperatures.

Integrating plasma, solid catalysts and process intensification may generate a synergistic effect. This can:We will investigate CO2 conversion to fuels and value-added chemicals in an energy efficient and sustainable way.

We will do this by the integration of non-thermal plasma catalysis and process intensification. Most of the vegetable oil comes from rapeseeds, sunflower seeds or soya beans. The rest is waste vegetable matter. It may be possible to gasify the waste vegetable matter and produce bio-ethanol, but the energy density of the crop remains low.

Some species of algae also produce vegetable oils as an cystic fibrosis news today storage mechanism. One species even produces cystic fibrosis news today C34 straight chain hydrocarbon.

This is approximately 2. But algal production of oil is not used as a method of producing biodiesel. This is because of the cost of the very large bioreactors needed to grow the algae over 4-5 days. Oscillatory Baffled Reactors (OBRs) are an intensified form of plug flow reactor.

Their niche application is the performance of long reactions in continuous, plug flow mode. Efficient growth of algae for biofuel is a large challenge that an OBR-based photobioreactor may be able to contribute to. This is due to its periodic regular mixing patterns and low and controllable shear.

It also has a relatively low energy consumption compared to stirred tanks. We would like to take this work further. This project will follow up on some interesting observations. These concern selectivity and catalyst formulation. Our previous work cystic fibrosis news today currently confidential, but you will find out the details when you start work here. You will investigate the preparation of sulphated zirconia and other acid catalysts. You will also characterise them.

Dr Kamelia BoodhooWe can tailor OBR baffle design to fit particular systems. We have basic proof-of-concept for significant improvements in baffle design liquid-liquid systems. This is at small scale. We would like to develop this further. This project cystic fibrosis news today taking forward the conventional design. We will develop new designs for specific applications.

A novel catalyst for the biodiesel reaction could improve the economics of biodiesel production. Such a solid basic catalyst would be viable and low temperature. It would simplify biodiesel production. This is because it removes the need for a constant supply of the current homogeneous supply, which is not regenerated. It would reduce the load on cystic fibrosis news today operations. In so doing, it would also reduce the environmental impact of the process, by reducing waste.

This project follows on from two completed PhD projects: Claire McLeod and Din Wan Yussof. It will investigate catalysts on tailored substrates for heterogeneous catalysis of biodiesel.

We will develop our own catalysts. We will also evaluate catalysts from a reactor engineering point of view. This will feed back to our partners at Cardiff University, who will modify and develop microstructured catalysts. Cystic fibrosis news today reactors perform much better if we can maintain the conditions throughout the reactor bed or the catalyst. Specific temperatures, heat fluxes, and so on all have an impact on reactor drez. This is not possible in most reactor configurations.

To maintain conditions, we must use fully-intensified units such as spinning disc reactors. But there infj a heat transfer technology that can be effective in overcoming cystic fibrosis news today of conventional reactors - the heat pipe.

It can be designed for operation at any reactor temperature. It can:This PhD project will involve studies on heat pipe behaviour.

I apologise, but, in my opinion, you are not right. Let's discuss it. Write to me in PM.

What words... super, a magnificent idea

I apologise, but I suggest to go another by.

I can not participate now in discussion - it is very occupied. I will return - I will necessarily express the opinion.

In my opinion it is obvious. I recommend to look for the answer to your question in google.com
