Title: Innovations of Steven A Blankenship
Introduction
Steven A Blankenship is an accomplished inventor based in Radcliff, KY (US). He holds a total of 9 patents, showcasing his significant contributions to the field of chemical engineering and gas purification technologies. His work primarily focuses on methods for purifying ethylene-containing gas streams, which are crucial in various industrial applications.
Latest Patents
Among his latest patents is a method and system for purifying an ethylene-containing gas stream. This innovative two-catalyst system features separate catalyst beds for the selective conversion of acetylene to ethylene. This process effectively reduces the concentration of acetylene, dienes, O2, and NOx. The ethylene-containing gas stream, such as an off-gas stream from a refinery catalytic cracking unit, is treated by first contacting it with a silver catalyst supported on a metal oxide. Subsequently, the gas stream is treated with a ruthenium catalyst supported on metal oxide. These catalysts are contained within contiguous continuous reactors or reactor compartments.
Another notable patent is a process for the purification of ethylene-containing feedstreams. This method is designed for feedstreams derived from steam crackers or fluid catalytic crackers (FCC). The feedstreams may also contain hydrogen, carbon monoxide, acetylenes, oxygen, and nitric oxides. The process involves contacting an ethylene-comprising gas stream with a Ru-based catalyst at reaction temperatures of at least 120°C. The result is an ethylene-containing feedstream that is essentially free of acetylenes, nitric oxides, and oxygen, with minimal loss of ethylene during purification.
