Abstract Scope |
Utilization of captured carbon dioxide (CO2) by converting it into valuable products, such as fuels, chemicals, plastics, and building materials is needed to offset the >36 GT/y of anthropogenic emissions. This presentation will describe two breakthrough processes invented and patented by Rutgers University for the production of low-carbon and carbon-negative composites. The first process, namely, Hydrothermal Vapor Synthesis (HVS), enables the production of feedstock anhydrous inorganic oxides, an essential precursor for carbonate ceramics, at temperatures <500˚C, which is up to 1000˚C lower than the temperatures of traditional pyrothermal reactions. The second process, called Gas-assisted Reactive Hydrothermal Liquid Phase Densification (g-rHLPD), enables low temperature (<100˚C) densification by using CO2 as a reactant with anhydrous oxides for creating strong, dense carbonate-bound ceramics with outstanding physical and chemical properties. Materials produced with these technologies will be presented and compared with the incumbent materials to demonstrate the outstanding low-carbon future awaiting materials manufacturing. |
