Title: Norman Macleod: Catalyst Innovation at Johnson Matthey Davy Technologies

Introduction

Norman Macleod is an inventor associated with Billingham, Great Britain, and Johnson Matthey Davy Technologies Limited. His patent work concerns the preparation of copper-containing catalysts, with a process designed to control catalyst composition and incorporate silica.

Latest Patents

Macleod is associated with 1 patent: “Method for Making Copper-Containing Catalysts.” The invention describes preparing a catalyst through two precipitation steps. An acidic copper-containing solution is combined with a basic precipitant to form a first precipitate, while an alkali metal aluminate solution is combined with an acidic solution to form a second precipitate. The precipitates are then mixed to create a catalyst precursor, which is washed, dried, and calcined.

The method specifies that at least 70% by weight of the catalyst’s copper is present in the first precipitate. It also introduces a silica precursor during one of the precipitation or mixing steps, producing a catalyst with a silica content, expressed as SiO, of 0.1 to 5.0 wt%.

Career Highlights

Macleod’s listed patent reflects work on catalyst manufacturing processes, particularly the preparation of copper-containing materials with defined composition.
