  • Patent number: 11485914
    Abstract: This invention relates to the recovery of hydrocarbons i.e. to a process and system for the production of synthetic crude oil from unconventional oil sources such as oil sands, oil shale, and similar materials. The process comprises pyrolysing the feedstock in a pyrolysis liquid comprising molten metal(s) or molten salt (s).
    Type: Grant

    Date of Patent: November 1, 2022
    Assignee: COMPOSITE RECYCLING CORP.
    Inventors: Roman Cintula, Frank Riedewald
  • Patent number: 10953444
    Abstract: Disclosed is a system and method for the recycling of waste composite feed materials such as printed circuit boards (PCBs), batteries, catalysts, plastic, plastic composites such as food packaging materials, for example Tetra PakĀ®, mattresses, compact disks (CDs, DVDs), automobile shredder residue (ASR), electric cable wastes, liquid display panels, mobile phones of various sizes or combinations of the above using a new pyrolysis system and method.
    Type: Grant

  • Patent number: 10865345
    Abstract: Disclosed is a process for treating waste plastic materials such as whole tyres, coarsely cut tyres, large plastic pieces, plastic composites such as hoses or combinations of above into gases, liquids and solids by direct heating in a pyrolysis liquid (1) such as molten salt or molten metal. The pyrolysis system is constructed such that the segregation of the light and heavy materials occurs within the pyrolysis chamber. The carbon black is segregated from the pyrolysis vapours via a cyclone and fractions of carbon black may be obtained by installing a number of cyclones in series so that different qualities of carbon black may be produced. Diesel or other oils, steel, carbon black, ZnO and synthesis gas are recovered; all of which can be feed streams to other processes. This process avoids the inefficient procedure of cutting the tyres or other plastic composites into small pieces before treatment by pyrolysis and also recovers valuable components.
