With a total of 8 patents to her name, Denise has established herself as a leading expert in the separation processes of various chemical compounds.

Latest Patents

Denise's latest patents focus on two distinct processes for separating ethylbenzene from complex feedstreams. The first patent outlines a method for separating ethylbenzene from a paraxylene-depleted feedstream that contains meta-xylene. In this process, Denise describes the use of a K-substituted Type Y zeolite to selectively enhance the concentration of ethylbenzene. A selected desorbent, ideally an aromatic hydrocarbon, is passed through the zeolite, allowing for the effective separation of these compounds.

The second patent describes a process for selectively adsorbing ethylbenzene from a stream containing one or more isomeric xylenes. In this invention, ethylbenzene is adsorbed on a gallium Beta zeolite, which demonstrates excellent selectivity for ethylbenzene over xylenes when a para-dialkylbenzene desorbent is utilized. Both of these innovations showcase Denise’s expertise in zeolite applications for chemical separation.
