Title: Neelesh Rane: Innovator in Contaminant Removal and Transalkylation Processes
Introduction
Neelesh Rane is a notable inventor based in Des Plaines, IL (US). He holds 2 patents that focus on innovative processes in the field of chemical engineering. His work primarily addresses the removal of contaminants from coal tar-derived crude phenols and the transalkylation of alkylated phenols.
Latest Patents
One of Neelesh Rane's latest patents is titled "Contaminant removal from coal tar-derived crude phenols." This patent describes a process for removing contaminants from coal-derived phenols by combining an extraction process with at least two adsorption zones containing adsorbents. The process utilizes liquid-liquid and acid-base extraction methods, with adsorbents such as clays and/or zeolites. This innovative approach can effectively reduce organonitrogen and organosulfur compounds to levels below 10 ppmw, resulting in a colorless product.
Another significant patent is "Transalkylation of alkylated phenols." This patent outlines transalkylation processes that employ catalysts made from three-dimensional 12-membered ring zeolites, which feature a combination of small and large pores. These catalysts enhance the conversion of alkylphenols to phenol, cresols, and alkylbenzenes from coal-derived liquid streams, outperforming traditional catalysts like HZSM-5 zeolite.
