Fecha de publicación: | 2014 | Editor: | Kluwer Academic Publishers | Citación: | Journal of Sol-Gel Science and Technology 69: 488- 497 (2014) | Resumen: | Carbon xerogels (CX) can be synthesized by microwave-assisted heating. The transfer of this technology to an industrial scale passes through the optimization of the variables that affect the process. The effect of the main operational variables, i.e., initial volume of the precursor, gelation and ageing time and temperature of the synthesis, on the final porous properties of CX has been evaluated. It was found that the development of porosity in the CX synthesised in the microwave oven is hardly influenced by the increase in the initial volume of the precursor solution. This suggests that it is feasible to scale up the production of these materials by means of microwave heating. Furthermore, the consumption of energy does not increase in proportion to the volume of xerogel synthesized. Thus, the process is energy efficient, saves a considerable amount of time and requires only a single device to carry it out. These advantages, along with the fact that a temperature variation of 10 C is not determinative in the xerogels' final properties, indicate that CX could be produced on a large scale in a cost effective way. © 2013 Springer Science+Business Media New York. | Versión del editor: | http://dx.doi.og/10.1007/s10971-013-3248-6 | URI: | http://hdl.handle.net/10261/132479 | DOI: | 10.1007/s10971-013-3248-6 | Identificadores: | doi: 10.1007/s10971-013-3248-6 issn: 0928-0707 |
