Title: The Innovations of Donald W Buchanan, Jr.
Introduction
Donald W Buchanan, Jr. is a notable inventor based in Wayne, NJ (US). He has made significant contributions to the field of chemical engineering, particularly in the area of catalytic processes. With a total of three patents to his name, Buchanan has demonstrated a commitment to advancing technology and improving industrial processes.
Latest Patents
Buchanan's latest patents focus on the process of vapor phase catalytic hydrogenation of maleic anhydride to gamma-butyrolactone. This innovative process achieves a conversion rate of 95% or more and a selectivity of 80% or more during prolonged production periods. The method utilizes an activated catalyst, which is prepared by reducing a catalyst composition that includes 30-65% by weight of CuO, 18-50% by weight of ZnO, and 8-22% by weight of Al2O3. The activation of the reduced catalyst composition occurs in hydrogen at a temperature of at least 400°C, preferably between 400°C and 525°C, with an optimal activation temperature around 425°C. The process is conducted under specific conditions, including a defined molar ratio of hydrogen to maleic anhydride, selected pressure during hydrogenation, defined feed rate space velocity, predetermined contact time, and suitable reaction temperature.
Career Highlights
Throughout his career, Buchanan has worked with several companies, including Isp Investments Inc. and Gaf Chemicals Corporation. His experience in these organizations has contributed to his expertise in chemical processes and innovation.
