  • Publication number: 20220041937
    Abstract: There is a process for the hydroconversion of mixtures of polymers or plastics which comprises the pre-treatment of the mixtures through methods selected from mechanical methods, chemical methods, thermal methods, or combinations thereof forming a pre-treated charge. The pre-treated charge is mixed with a hydrocarbon vacuum residue, optionally pre-heated, to form a reactant mixture. The reactant mixture is fed to a hydroconversion section in slurry phase, together with a catalyst precursor containing Molybdenum, and a stream containing hydrogen, forming a reaction effluent. The effluent is separated into at least one high-pressure and high-temperature separator in a vapour phase and a slurry phase. The separate vapour phase is sent to a gas treatment section with the function of separating a liquid fraction from the gas containing hydrogen and hydrocarbon gases having from 1 to 4 carbon atoms; said liquid fraction comprising naphtha, atmospheric gas oil (AGO), vacuum gas oil (VGO).

  • Patent number: 4196649
    Abstract: A circular saw is provided which comprises two blades, one blade being locked at a fixed point of the driving shaft, and the other being rigid, a bushing coupled to a sleeve rotating with said driving shaft. The bushing slides along the sleeve, under the action of a lead nut coupled to a screw or a worm driving shaft rotated by a geared motor. By appropriate rotation of the driving shaft it is possible to vary continuously the distance between the two blades.
