| Abstract Scope |
Cellulose is an abundantly available natural resource that can be utilized for a variety of industrial applications. Although cost-effective to produce, a need has been identified by manufacturers to develop energy-efficient dewatering of cellulosic nanomaterials, as cellulosic nanomaterials are not economical to ship long distances while containing significant water content (>95 wt.%). An electrochemically-assisted sustainable and energy efficient dewatering technology is currently under development by Faraday. Innovative reactor designs are utilized to demonstrate the feasibility of a cost-effective, industrially viable, and energy efficient ElectroDewatering approach capable of generating >50 wt.% final solid content for both cellulose nanocrystals (CNC) and cellulose nanofibers (CNF). The material properties (structure, particle size) were maintained through dewatering, and materials with ~25-30 wt.% final solids were successfully rehydrated and redispersed via vortexing. The pulse process approach reduced the energy use by at least 50% compared to thermal drying at similar dewatering performance. |
