Title: Gary Evans and His Formaldehyde Manufacturing Patent.

Introduction

Gary Evans is an inventor associated with Reading, Great Britain. His listed patent concerns a process for producing formaldehyde from methanol and identifies Johnson Matthey Davy Technologies Limited as his company.

Latest Patents

The supplied information lists one patent for Evans: “Process for formaldehyde manufacture.” The invention describes feeding methanol and an oxygen-containing gas into a reactor, where they react in the gas phase over a catalyst containing iron and molybdenum oxides. The process then recovers an outlet stream containing formaldehyde and carbon monoxide.

The patent specifies that the catalyst contains copper at a concentration of at least 0.025 wt %, or at least 0.05 wt %. It also states that the outlet stream’s carbon monoxide-to-formaldehyde molar ratio is at least 5% lower than the ratio obtained using a catalyst containing essentially no copper.

Career Highlights

Evans’s listed work is connected to chemical process technology at Johnson Matthey Davy Technologies Limited. His patent focuses on catalyst composition and the production of formaldehyde from methanol.

Collaborations

The supplied information names Robert Häggblad and Kaisa Kisko as coworkers. It does not specify their roles in the patent or describe particular collaborations with Evans.

Conclusion

Gary Evans’s listed patent addresses formaldehyde production and highlights the use of copper in an iron- and molybdenum-oxide catalyst to reduce the outlet stream’s carbon monoxide-to-formaldehyde ratio.
