Title: The Innovations of John E Sauer

Introduction

John E Sauer is a notable inventor based in Washington Crossing, PA (US). He holds a total of 4 patents and has made significant contributions to the field of gasoline upgrading processes. His work has been instrumental in developing methods to produce low sulfur gasoline, which is crucial for reducing environmental impact.

Latest Patents

One of John E Sauer's latest patents involves a gasoline upgrading process that produces low sulfur gasoline from a catalytically cracked, sulfur-containing naphtha. This process includes fractionating the naphtha feed into two fractions: a low boiling fraction where the majority of sulfur is present in the form of mercaptans, and a high-boiling fraction where sulfur is predominantly in non-mercaptan forms such as thiophenes. The low boiling fraction undergoes desulfurization through a non-hydrogenative mercaptan extraction process, which retains the olefins present in this fraction. The second fraction is desulfurized by hydrodesulfurization, which results in some saturation of olefins and a loss of octane. To restore the octane loss, treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5, is applied. This results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha, while some recombined sulfur in the form of mercaptans is removed in the final hydrotreatment.
