Title: Akira Ako: Innovator in Pulp Production Technology
Introduction
Akira Ako is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of pulp production, holding 2 patents that focus on innovative methods for producing pulp and treating black liquor.
Latest Patents
One of his latest patents is a method for the production of pulp. This process allows for high yield pulp production without the use of sodium sulfide and avoids high-temperature and high-pressure conditions typically associated with the Kraft process. The method involves processing wood chips for hydrophilization at room temperature using a dilute caustic soda aqueous solution. It selectively modifies lignin in dilute nitric acid and digests the wood chips under atmospheric pressure. The process also enables the collection of lignin from the isolated black liquor.
Another significant patent is related to a black liquor treatment method. This innovation efficiently sorts lignin and alkali from alkaline black liquor discharged from the pulp and paper manufacturing industries. The treated water is purified, with acid added to adjust the pH to between 2.5 and 3.5. An aggregating agent is introduced to facilitate the settling of lignin, allowing for the separation of lignin and clean water. Ozone gas, preferably in a micro bubble state, is then used for a contact reaction with the clean water.
Career Highlights
Throughout his career, Akira Ako has worked with several companies, including K.I. System Co., Ltd. and Nihon Cellulose Co., Ltd. His work has focused on enhancing the efficiency and sustainability of pulp production processes.
Collaborations
He has collaborated with notable coworkers such as Sadao Kitagawa and Kazumasa Koike, contributing to advancements in the field of pulp and paper technology.
Conclusion
Akira Ako's innovative approaches to pulp production and black liquor treatment demonstrate his commitment to improving industrial processes. His patents reflect a significant step forward in sustainable practices within the pulp and paper industry.
