Title: Innovations of Cheng-Yih Jenq
Introduction
Cheng-Yih Jenq is a notable inventor based in Princeton, NJ, with a significant contribution to the field of chemical engineering. He holds three patents that showcase his innovative approaches to chemical processes. His work primarily focuses on the catalytic oxidation of polynuclear aromatic hydrocarbons and the thermal dealkylation of alkylated phenols.
Latest Patents
One of his latest patents involves the catalytic oxidation of polynuclear aromatic hydrocarbons. This process enhances the oxidation of anthracene in an oxygen-containing gas using a ceric ammonium nitrate catalyst system. The method increases turnover ratios through several means, including the use of acetic acid as a solvent and pure molecular oxygen as the oxidizing agent. Additionally, ammonium vanadate acts as a promoter, and acetic anhydride is added to react with water produced during the oxidation reaction. This innovative approach allows for the continuous production of anthraquinone from anthracene.
Another significant patent by Jenq is the low-temperature hydrodealkylation of alkylated phenols. This process involves reacting a feed mixture of mono and poly-alkylated phenols with gaseous hydrogen at elevated temperatures and pressures. The method aims to produce a phenol-containing product with increased selectivity and yield. For feedstream mixtures with high phenol concentrations, a prior distillation step is recommended to prevent undesired reactions during the hydrodealkylation process.
