Title: The Innovative Contributions of Gerald J Nacamuli

Introduction

Gerald J Nacamuli is a notable inventor based in Mill Valley, California, recognized for his significant contributions to the field of chemical engineering. With a total of 11 patents to his name, Nacamuli has made remarkable advancements in the production of high-purity chemicals, particularly in the aromatics sector.

Latest Patents

One of Nacamuli's latest patents focuses on the manufacture of high purity benzene and para-rich xylenes by combining aromatization and selective disproportionation of impure toluene. This innovative process allows for the reaction of impure toluene to yield benzene, toluene, and a para-rich xylene stream that is substantially free of close-boiling non-aromatics. The impure toluene used in this process contains at least 70 wt % toluene and between about 0.2 wt % and about 5 wt % close-boiling non-aromatics. Additionally, the process may involve aromatizing a naphtha over a non-acidic catalyst, followed by passing the impure toluene from the aromatization step over an acidic intermediate pore zeolite to produce a para-rich xylene stream and chemically pure benzene. Another significant patent relates to the production of aromatics in parallel reformers, which reform a full-boiling range hydrocarbon feed in two parallel stages. This method maximizes the catalyst life of the heavy cut reformer and reduces the complexity of the plant by preferentially sending the higher purity hydrogen to the heavy cut reformer.
