  • Patent number: 11242490
    Abstract: The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.
    Type: Grant
    Filed: February 6, 2019
    Date of Patent: February 8, 2022
    Assignees: The University of Nottingham, Tata Steel Limited
    Inventors: Bidyut Das, Sanjay Chandra, Atanu Ranjan Pal, Pratik Swarup Dash, Munish Sudan, Eleanor Binner, Christopher Dodds, Edward Henry Lester, Orla Williams, Samuel Kingman

  • Patent number: 7566436
    Abstract: A mixing reactor for mixing efficiently streams of fluids of differing densities. In a preferred embodiment, one of the fluids is supercritical water, and the other is an aqueous salt solution. Thus, the reactor enables the production of metal oxide nanoparticles as a continuous process, without any risk of the reactor blocking due to the inefficient mixing inherent in existing reactor designs.
