Latest Patent Applications

Leah Fraiberg's latest patent applications include a process titled "Optimization of Chemical Consumption in Biomass Delignification." This process involves a system with a first and second vessel, where biomass containing lignin, hemicellulose, and cellulose fibers is treated. The method includes providing an aqueous acidic composition with sulfuric acid, a modifier component, and a peroxide component. The biomass is exposed to these components, creating a reaction mass that undergoes a controlled exothermic delignification reaction. The process allows for the removal of a predetermined amount of lignin from the biomass, assessed by measuring the first kappa number. Once this target is reached, the biomass is transferred to the second vessel for further processing.

Conclusion

Leah Fraiberg is a dedicated inventor whose work in biomass delignification showcases her commitment to innovation in sustainable practices. Her latest patent applications reflect her expertise and potential impact in the field.
