Latest Patents

Pekka Oinas holds a patent for "Aqueous lignin dispersions and methods of preparing the same." This invention details a method of forming colloidal lignin particles by dissolving lignin in a mixture of organic solvents. The solution is then fed into water to create a colloidal dispersion of lignin. The solvents used in this process are recovered through methods such as distillation and reused, promoting sustainability. Water is removed from the colloidal dispersion by ultrafiltration and is also reused in the process. The concentrated colloidal dispersion is subsequently dried by spray drying. This invention is particularly beneficial in applications where the colloidal nature of lignin provides advantages over bulk lignin.
