Title: Innovations and Contributions of Chakka Sudhakar in Hydrocarbon Processing

Introduction

Chakka Sudhakar, based in Wappingers Falls, NY, is a prolific inventor with a remarkable portfolio of 24 patents. His work primarily revolves around the upgrading of hydrocarbon oils, showcasing his expertise and innovative approach in the field of chemical engineering.

Latest Patents

Sudhakar's latest patents include a pioneering process for upgrading hydrocarbon oil. This catalyst-assisted upgrading process aims to treat hydrocarbon oil feeds in order to reduce the total acid number (TAN) and enhance the API gravity. The process involves blending a hydroprocessing catalyst, based on a support such as alumina, with the hydrocarbon oil feed to form a slurry that is then treated with hydrogen under moderate temperature and pressure, often utilizing a tubular reactor. This method minimizes or avoids deposit formation, representing a significant advancement in hydrocarbon processing.

Another notable patent addresses the hydrodenitrogenation of hydrocarbons. In this process, a naphtha or middle distillate hydrocarbon is hydrodenitrogenized by hydrotreating in the presence of a catalyst that includes a carbon support along with specific metals such as molybdenum or tungsten, a non-noble Group VIII metal, and chromium. This innovation contributes to the efficiency and refinement of hydrocarbon processing techniques.
