Other Zeolite Forms-Colloids, Sheets, Films and Fibers

Other Zeolite Forms-Colloids, Sheets, Films and Fibers 

In recent years zeolites have been utilized in non-conventional forms which emphasize certain chemical or engineering characteristics of the materials. Novel forms include thin sheets made by coating processes and paper-making technology and zeoUte-contairiing fibers. 

Thin zeolite sheets offer improved mass transfer for possible rapid cycle adsorption processes. One of the first studies of zeolite as fillers in paper-making was issued to NCR in 1955, although at that time the term zeolite was more often used to describe any ion exchanger whether or not it was actually a crystalline microporous zeolite [95]. A later patent described the incorporation of micropo-rous zeolite powders in paper sheets [96]. More recently a number of patents described zeolite-containing papers in adsorption processes [97-99].
