Septimus H Liang is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of activated carbon technology, particularly in applications related to environmental safety and chemical warfare protection. With a total of 3 patents, his work showcases innovative approaches to enhancing the performance and safety of activated carbon materials.

Latest Patents

One of Liang's latest patents is focused on an organic amine-impregnated activated carbon composition. This novel composition is designed for use in breathing gas filters, enhancing the removal of various toxic perfluorocarbons. The patent outlines three processes for impregnating activated carbon with organic amines, including a method that involves placing the amine in contact with substantially dry activated carbon. This process is conducted in an environment devoid of oxidizing gases, such as oxygen, and requires heating the carbon and amine for an extended period while maintaining this oxidizer-free environment. Additionally, pretreatment procedures are disclosed to enhance both the shelf-life and service-life of the amine-impregnated activated carbon.

Another significant patent involves the preparation of low chromium active charcoal through freeze-drying techniques. This innovation addresses the carcinogenic risks associated with chromium VI, which is commonly found in activated charcoal used for protection against chemical warfare agents. By employing freeze-drying methods, Liang has demonstrated that the quantity of harmful metals can be reduced by as much as 50% without compromising the charcoal's performance.
