Hot water regeneration was executed only with the adsorbent resin. This kind of regeneration is mentioned in literature [3]. The drying of the adsorbent resin is not necessary, since all the experiments are carried out in the liquid phase. The supply of hot water is less expensive than steam generation. Only the energy for heating the water must be applied, since the energy for evaporating the water and superheating the steam is saved. First results of the hot water regeneration are shown in Fig. 7.

A new, universal powder coating CVD process has been developed that combines a low‐pressure circulating fluidized bed with a microwave or radio‐frequency plasma to coat particles on a kilogram scale. This is illustrated by the CVD of dense titania coatings with a well‐defined thickness of 10 nm or greater. The figure shows a ToF‐SIMS image for the Ti in the titania.
