Latest Patents

Yun'an Zhou holds a patent for a process titled "Process for preparing cellulose solution and equipment therefor." This invention provides a method for preparing a cellulose solution by continuously mixing NMMO with a relatively low concentration and non-activated pulp. The process involves dewatering the mixed premix in evaporation dewatering equipment until an NMMO concentration suitable for swelling is achieved. Sufficient swelling is then carried out, followed by depressurized evaporation dewatering and dissolving using thin-film-evaporation equipment. This results in a high-concentration, uniformly-dissolved cellulose solution. The invention effectively resolves the conflict between uniform mixing and sufficient swelling, while also preventing safety issues related to high concentration NMMO in conventional technologies.
