Title: Innovations of Jianxin Chen in Wood Pulp Processing
Introduction
Jianxin Chen is a notable inventor based in Vancouver, Canada, recognized for his contributions to the field of wood pulp processing. He holds 2 patents that focus on improving the efficiency and environmental impact of chemical wood pulp bleaching processes. His innovative approaches have the potential to revolutionize the pulp and paper industry.
Latest Patents
One of Jianxin Chen's latest patents is a process for delignification and bleaching of chemical wood pulps. This process utilizes hydrogen peroxide and dicyandiamide as an activator, resulting in a higher degree of delignification and brightness of the pulp while overcoming issues related to fiber degradation. The method involves adding these chemicals to a chemical wood pulp slurry under alkaline conditions. Another significant patent involves bleaching lignocellulosic material with in-situ-generated dioxirane. This process produces a chemical pulp that contains reactants capable of generating dioxirane within the pulp. By mixing a pulp with a carbonyl compound, such as acetone, and an oxygen donor, like monoperoxysulfate, a water-soluble dioxirane is created. This innovative bleaching process is both environmentally and economically viable due to the recycling of the reactants used to produce dioxirane.
