Title: Innovations of Nicholas C Dispenziere, Jr.

Introduction

Nicholas C Dispenziere, Jr. is a notable inventor based in Wall, NJ (US), recognized for his contributions to the field of catalysis. He holds a total of 9 patents, showcasing his innovative approach to chemical processes and materials.

Latest Patents

One of his latest patents is focused on a catalyst comprising amorphous nickel oxide (NiO) on a silica/alumina support. This invention is significant for the production of dimer products and higher olefin products from lower olefins such as propylene and butene. The catalyst composition is designed to achieve high yields with an average degree of branching in the dimer products of less than about 1.6 methyl groups per molecule, typically ranging from about 1.0 to 1.4 methyl groups per molecule. The catalyst is prepared by precipitating a water-insoluble nickel salt onto a silica support that has been impregnated with a metal oxide. The activation of the catalyst occurs through calcination in the presence of oxygen at temperatures between 500°C and 700°C.

Career Highlights

Throughout his career, Nicholas has worked with prominent organizations, including Exxon Research and Engineering Company and Exxon Chemical Patents, Inc. His experience in these companies has contributed to his expertise in developing innovative catalytic processes.
