  • CO CURRENT MIXER, APPARATUS, REACTOR AND METHOD FOR PRECIPITATING NANOPARTICLES
    Publication number: 20160074823
    Abstract: A high pressure tubular reactor for production of nanoparticles by precipitation has unidirectional fluid flows of a precursor and supercritical water directed from inner and outer coaxial inlets to an outlet via a reaction zone yearly downstream of the inlets. The inner inlet is for supercritical fluid, and the outer inlet is for a precursor.
    Type: Application
    Filed: October 16, 2015
