Latest Patents

One of Hedge's latest patents is focused on the "Separation of cyclic compounds with molecular sieve adsorbent." This invention describes a method for selectively adsorbing one cyclic compound from a fluid mixture that contains a structurally similar cyclic compound. The process utilizes molecular sieves, specifically crystalline aluminosilicate zeolites, which have been partially dehydrated at temperatures ranging from 80°C to 300°C. For instance, m-xylene can be effectively separated from p-xylene using NaY zeolite that has been partially dehydrated at 125°C and contains approximately 12 wt % water.

Another significant patent by Hedge is for a "Catalyst for the oxidation of butane to maleic anhydride." This invention presents a catalyst comprising SB-Ni-Mo, which has demonstrated high selectivity, stability, and longevity in converting butane to maleic anhydride. The patent also notes that other metals, such as Co, Cu, or Zn, can be substituted for Ni with similar results. An improved method for preparing this catalyst is also included in the patent.
