Title: Innovations of John Bruce Wallace, Jr.

Introduction

John Bruce Wallace, Jr. is a notable inventor based in Red Hill, PA (US). He has made significant contributions to the field of nitrogen purification processes. With a total of 2 patents, his work focuses on improving the efficiency and cost-effectiveness of nitrogen production.

Latest Patents

Wallace's latest patents include a bulk nitrogen purification process that requires no hydrogen. This innovative process effectively removes parts-per-million quantities of unwanted species such as oxygen, carbon monoxide, hydrogen, carbon dioxide, and water from a cryogenically produced nitrogen gas stream. The method employs an oxygen removal step prior to a nickel-based catalytic adsorption step, eliminating the need for hydrogen regeneration in either step. Ultrapure nitrogen heated to less than 500°C is utilized to purge and hold the beds used for unwanted species removal, thus reducing regeneration cycle time and cost.

Another significant patent is a method for regenerating a nickel-based catalytic adsorbent without using hydrogen in each cycle. This method involves interim regenerations, which include heating the bed, flowing ultra-high purity nitrogen without hydrogen through the bed to remove adsorbed species, and cooling the bed. This process prepares the adsorbent bed for the removal of unwanted species contained in cryogenically produced nitrogen, ultimately leading to the production of ultra-high purity nitrogen.
