Title: Innovations by Jian Er Jiang in Chemical Pulping
Introduction
Jian Er Jiang is an accomplished inventor based in Queensbury, NY (US). He has made significant contributions to the field of chemical pulping, particularly in methods that enhance the quality of cellulose pulp. His innovative approach focuses on minimizing transition metal ions during the pulping process, which is crucial for producing environmentally friendly pulp.
Latest Patents
Jian Er Jiang holds a patent for a method that minimizes transition metal ions during chemical pulping in a digester by adding a chelating agent. This method results in the production of kraft cellulose pulp that is better suited for totally chlorine-free or elemental chlorine-free bleaching. By maintaining the effective alkalinity of the pulp during the cooking stage, he reduces the charged acid groups significantly compared to conventional methods. The process involves heating the cellulosic material to release transition metals and using a chelating agent, such as EDTA, to form complexes that can be removed before bleaching.
