Title: Rodney Foo: Innovator in Selective Catalytic Reduction Technologies

Introduction

Rodney Foo is a notable inventor based in Caversham, GB. He has made significant contributions to the field of selective catalytic reduction (SCR) technologies, holding 2 patents that focus on improving the efficiency of exhaust gas treatment systems.

Latest Patents

His latest patents include innovations such as "Coated articles having high kNOx/kSOx ratios for selective catalytic reduction." This patent describes articles that comprise a catalyst film made of VOx, MoO, or WO, and TiO deposited on a substrate. These articles are designed for the SCR of NOx in exhaust gases. The methods for producing these articles involve depositing a catalyst film on a substrate to create a coated substrate, which is then calcined. When utilized in an SCR process, these coated articles exhibit enhanced activity for NOx conversion while maintaining reduced activity for SOx conversion. Additionally, lightweight coated articles with high catalyst loads can be fabricated at the same or reduced dimensions compared to laminated articles, providing increased kNOx/kSOx ratios even from relatively thin catalyst films. These innovations are particularly valuable for power plant operations, where managing sulfur trioxide generation is critical.

Another significant patent by Foo is focused on "Low temperature urea-SCR operation in the presence of high sulphur flue gas." This patent outlines systems and methods for the continuous operation of a urea-SCR system at low temperatures (200-350°C) in environments with high SOx containing flue gas. The methods involve introducing a solution of urea and an NO forming compound, preferably an alkaline earth metal nitrate, into an exhaust stream before it contacts an SCR catalyst.
