Latest Patents

David's latest patents include a solvent and recovery process for lignin. This invention describes methods for obtaining purified lignin from pretreated lignocellulosic biomass feedstock. The process aims to recover lignin with a very low level of impurities, such as metals and ash. It also allows for a narrow molecular weight distribution, enabling the production of lignin with predetermined molecular weights. The method involves mixing a lignin-containing feedstock with a solvent solution, resulting in a fractionation that separates the lignin-rich and solvent-rich phases.

Another notable patent is related to the manufacturing of underground caverns in carbonate rock. This acid dissolution process is designed to create caverns suitable for storing large volumes of gaseous or liquid materials. These caverns can be utilized for various applications, including the storage of fossil fuels and hazardous waste materials. Additionally, the caverns can serve purposes involving human access, such as recreation or research.
