Modelling of reactors devoted to the thermal treatment of waste and biomass is a very complex task. It has to represent the physical and chemical phenomena occurring at different scales with a feedstock which is often neither completely known nor homogeneous. The first difficulty to overcome is associated to the description of the intrinsic reactio...
In this study, the performance of three nano-composite energy storage absorbents; Vermiculite-CaCl2 (SIM-3a), Vermiculite-CaCl2-LiNO3 (SIM-3f), and the desiccant Zeolite 13X were experimentally investigated for suitability to domestic scale thermal energy storage. A novel 3 kWh open thermochemical reactor consisting of new meshed tube air diffusers...

There is continuous increase in quantum and variety of waste being generated by anthropogenic activities. Burgeoning amount of waste being generated has potential to harm the environment and human health. Aggravating the problem, ever-increasing energy demand is putting strain on the non-renewable sources of energy and there is huge gap between the...

A brief review has been done of technologies involved in the exploitation of biogenic wastes, in order to provide an introduction to the subject from the technological perspective. Biogenic waste materials and biomass have historically been utilised for thousands of years, but a new conversation is emerging on the role of these materials in modern ...
Les procédés de stockage de chaleur haute température par voie thermochimique solide/gaz présentent un grand intérêt pour des applications à des centrales solaires thermodynamiques. Le couple réactif CaO/Ca(OH)2 est adapté à cette application pour des déstockages entre 350 et 550°C sous des pressions de vapeur entre 0,2 et 2bar. Les paramètres de t...

Terrestrial lignocellulosic biomass has the potential to be a carbon neutral and domestic source of fuels and chemicals. However, the innate variability of biomass resources, such as herbaceous and woody materials, and the inconsistency within a single resource due to disparate growth and harvesting conditions, presents challenges for downstream pr...
