Introduction

John W Graydon is a notable inventor based in Toronto, Canada. He has made significant contributions to the field of carbon absorption materials, particularly through his innovative patents. With a total of three patents to his name, Graydon's work focuses on the production of biochar absorbents from anaerobic digestate.

Latest Patents

One of Graydon's latest patents describes a novel carbon absorption material formed from anaerobic digestate. This material features a hollow tubular structure, which is particularly effective in converting hydrogen sulfide in biogas. It also absorbs the converted sulfur and sulfur compounds from biogas into its structure. After its use as a hydrogen sulfide absorbent, the material can be repurposed as a horticultural or agricultural product or as sulfur-impregnated activated carbon. The process for producing this innovative carbon absorption material involves using a humidified inert gas over a temperature range of approximately 500°C to 900°C. This thermal treatment is relatively mild, allowing the fibrous structure of the source material to be retained while removing cellulosic and hemicellulosic components from the anaerobic digestate.
