Carbon materials possess useful properties for several applications, such as: (i) stability in acidic/basic media; (ii) possibility to control, to some extent, the porosity and the surface chemistry; (iii) structural stability at high temperatures; and (iv) easy recovery of expensive metals (by burning away the support). Due to the high specific surface area, activated carbons have been traditionally used as adsorbents or as supports for metal catalysts; whereas graphitic materials having high conductivity can be used as […]

The general perception of chemical reactors is generally associated with two main embodiments: a tank with a stirrer or a pipe. These reactors are still the workhorses of the chemical industry, with particular focus on stirred tanks. The chemical industry in Europe is one of the sectors performing better in terms of reducing its footprint. The energy intensity of this industry was halved in 26 years. One of the main areas of optimization is on mixing operations, particularly those […]

Process Intensification (PI) is a very important stage to reach feasible chemical processes towards large-scale implementation. PI implies the development of new devices or engineering methods able to improve yield and selectivity attained in the conventional route. Usually, PI strategies comprise safer, cleaner, and smaller plants promoting higher energy efficiency by reducing equipment and/or steps required to achieve the desired product.
