Latest Patents
Louise Dufresne holds 1 patent for her invention titled "Catalyst for aromatization of olefins and paraffins." This patent describes an aromatization catalyst obtained by physically mixing a pentasil type zeolite, such as H-ZSM-5, with a zinc oxide-alumina co-precipitate. The weight ratio of the zeolite to the co-precipitate ranges from 4.3 to 28.3. Additionally, the Zn/Al atomic ratio in the co-precipitate may vary from about 0.16 to 25.0. This composite catalyst is designed to yield greater amounts of aromatics, particularly BTX aromatics, when contacted with an olefinic and/or paraffinic feedstock compared to the respective zeolite alone.
