  • Patent number: 4877418
    Abstract: Briquettes are tested to decrease efflorescence and to improve abrasion resistance and surface appearance, by dipping or spraying the formed briquettes with a solution of polyvinyl alcohol having a concentration greater than 1 part of polyvinyl alcohol to 250 parts of water.
    Type: Grant
    Filed: November 6, 1987
    Date of Patent: October 31, 1989
    Assignee: Coal Industry (Patents) Limited
    Inventors: Joseph Goleczka, Walter Harris, John Pringle
  • Patent number: 4787913
    Abstract: A cold coal briquetting process comprises mixing fine coal with polyvinyl alcohol and a hardening agent selected from iron oxide, phosphate rock and bauxite or combination of two or more thereof. The process permits economies in process and capital costs compared to existing briqueting processes, while still producing satisfactory briquettes.
    Type: Grant
