The project aims to coat activated carbon with silicon or silicon carbide layers using chemical vapour infiltration. By this coating the resistance against abrasion and reactive chemicals is enhanced. In the first two project periods the feasibility of the new process was demonstrated and the produced materials have been characterised. In the final period the reactor concept should be scaled up in order to produce the adsorbents in a 100g scale. This is nessessary to investigate the adsorption properties under abrasive and reactive conditions similiar to industrial applications. Furthermore alternative aluminum based coatings will be studied.
