    Abstract: The present invention is related to the treatment of plastic material to be destined for chemical recycling processes for the valorisation of substantially plastic material otherwise destined for disposal.
    In particular, the invention concerns a process for the pyrolysis of substantially plastic material to obtain at least liquid hydrocarbons at 25° C. comprising the following steps: a) feeding to a pyrolysis reactor a substantially plastic material at least partially in the molten state; b) subjecting said substantially plastic material fed to a pyrolysis reactor to at least an analytical measurement “Ax” with in-line mode; c) determining the value of at least one “Px” property of said substantially plastic material by means of said at least one analytical measure “Ax”; d) installing at least one “Ox” parameter of the pyrolysis process based on the value of this at least one “Px” property; characterised by the fact that at least one analytical measurement “Ax” provides or consists of the measurement of the spectrum in reflection of the light of the substantially plastic material.

    Abstract: The present invention relates to the treatment of plastic materials to be used for chemical recycling processes for the enhancement of substantially plastic materials otherwise destined for disposal.
    Specifically, the invention relates to a process for the pyrolysis of substantially plastic material to obtain at least hydrocarbons that are liquid at 25° C., comprising the following steps: a) feeding a substantially plastic material to a pyrolysis reactor; b) bringing said material in said pyrolysis reactor to a temperature of between 330° C. and 580° C. in the substantial absence of oxygen and at a pressure of between atmospheric pressure and 13 bara; c) maintaining said material in said pyrolysis reactor for a sufficient amount of time to produce an effluent in the gaseous state; d) partially or fully condensing said effluent in the gaseous state, so as to form at least one fluid comprising hydrocarbons that are liquid at 25° C. and which quantitatively is at least 10% by mass with respect to the mass of substantially plastic material fed; e) carrying out an assessment of at least one property “Px” of the liquid condensed from said effluent in the gaseous state by means of at least one measurement “Ax” of the spectrum in transmission, reflection or transflexion on said condensed liquid; f) adjusting at least one process parameter “Ox” according to said assessment of at least one property “Px”; g) repeating steps e) and f) iteratively so as to keep the said at least one property “Px” substantially constant over time.
