Latest Patents

Rautkari holds a patent for "Aqueous lignin dispersions and methods of preparing the same." This invention outlines a method for forming colloidal lignin particles. The process involves dissolving lignin in a mixture of organic solvents, which is then fed into water to create a colloidal dispersion. 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. The concentrated colloidal dispersion is subsequently dried using spray drying techniques. This invention can be particularly beneficial in applications that require the unique properties of colloidal lignin over bulk lignin.
