Title: The Innovative Contributions of David W. Rumsey
Introduction
David W. Rumsey is a notable inventor based in Plainfield, IL (US). He has made significant contributions to the field of gasoline upgrading processes. His innovative work has led to the development of a patented method that enhances the quality of gasoline while reducing sulfur content.
Latest Patents
David W. Rumsey holds a patent for a gasoline upgrading process. This process involves upgrading a sulfur-containing catalytically cracked naphtha to form a low-sulfur gasoline product. The method retains the octane contribution from the olefinic front end of the naphtha. Initially, the mercaptan sulfur in the front end of the cracked naphtha is converted to higher boiling disulfides through oxidation. The resulting olefinic, high-octane sulfur-free material can be blended directly into the gasoline pool. The back end, which contains higher boiling sulfur components, is hydrotreated to produce a desulfurized product. This product undergoes further treatment with a catalyst, preferably a zeolite such as ZSM-5, to achieve a higher octane value. A final desulfurization step may be applied to reduce organic sulfur to acceptable levels.
