About This PhD Project

Project Description

Since all the UK’s industrial activities need to reduce carbon emissions 57 % by 2030 on 1990 levels as part of the “fifth carbon budget”, decreasing the cost of carbon capture technologies is an important concern for all energy intensive sectors. Particularly power generation plants could divert the extra electricity during night-time for CO2 capture at high emitter industrial sites, assisted with radiofrequency heating using the lower nocturnal price rates. Radiofrequency heating is a greener and innovative technology which can contribute to the heating needed for the adsorption-desorption cycles of solid, low cost CO2 sorbents which require high temperatures of 600 and 800 oC respectivaely, considering a magnetic material as the heating source. This material could be the own reactor or the catalyst support in the energy intensive chemical industries (refineries, hydrogen and ammonia plants, steel and cement plants). Normally these plants will have emissions from coal, naphtha, or methane, so the CO2 concentration will be around 15-40 % in the feedstream, posing fuel specific challenges in the capture process. The development of magnetic catalyst will be studied for optimisation of the whole process, so the heating released will be a great advantage for the whole energy balance. CaO based sorbents will be considered but other alternatives could be also studied.
