Title: **Innovator John William Stairmand: Pioneering Advances in Catalytic Processes**

Introduction

John William Stairmand, an esteemed inventor based in Chester, GB, has made significant contributions to the field of chemical engineering with a focus on catalytic processes. With a portfolio of 14 patents, his innovative approaches have paved the way for advancements in steam-methane reforming and Fischer-Tropsch synthesis.

Latest Patents

One of Stairmand's latest patents involves an apparatus for steam-methane reforming that allows methane to react with steam, generating carbon monoxide and hydrogen in a specialized catalytic reactor. This cutting-edge process entails the gas mixture passing through a narrow channel at temperatures ranging from 750°C to 900°C, with a residence time of less than 0.5 seconds. The system utilizes a catalyst, ensuring that only rapid kinetic reactions occur. Heat is efficiently supplied through the combustion of methane in adjacent channels, while a steam-to-methane ratio of approximately 1.5 is maintained. Almost all methane undergoes reforming, primarily forming carbon monoxide, which is then utilized in Fischer-Tropsch synthesis. Following this process, the remaining hydrogen may be redirected back to combustion channels. Additionally, the steam for the reforming step can be generated from water produced during chemical reactions, enhancing the sustainability of the methodology.

Another key patent outlines the design of a catalytic reactor comprising multiple sheets that define flow channels. Each channel contains corrugated foil coated with catalytic material, allowing for the simultaneous supply of different gas mixtures at varying pressures. This design enables distinctive chemical reactions, facilitating the transfer of heat from exothermic to endothermic reactions. This reactor is ideal for compact plants, conducting steam-methane reforming and Fischer-Tropsch synthesis, thereby converting methane into valuable long-chain hydrocarbons.
