PROCESS TO PRODUCE A PYROLYSIS OIL COMPRISING LIQUID HYDROCARBONS FROM PLASTIC MATERIAL FROM AN INTERMITTENT ENERGY SOURCE, AND RELATIVE PLANT
Process for producing a pyrolysis oil comprising liquid hydrocarbons from plastic material, preferably waste material. The process is characterized by the use of an energy source preferably of an intermittent nature (and of variable intensity), such as for example solar radiation. The plastic material enters a pyrolysis reactor, heated with a molten salt thermal fluid. Said molten salts are heated by said intermittent source to a temperature that is not fixed but variable within a predetermined range. In particular, when the availability of the energy source is equal to or beyond a predetermined maximum value, the temperature of said molten salts is brought to the upper end of said range. Conversely, when the availability of the energy source is equal to or lower than a predetermined minimum value, the temperature of said molten salts is brought to the lower end of said range. For intermediate availability values, the temperature can also be brought to intermediate values, for example by following a linear profile. The pyrolysis temperature follows the temperature of the molten salts. The pyrolysis pressure, on the other hand, is modulated so that it is higher (at least 2.5 bara) when the pyrolysis temperature is lower and lower (no more than 2 bara) when the pyrolysis temperature is higher. Surprisingly, it has been discovered that by operating in the specified way, the quality of the pyrolysis oil obtained is kept constant, even for significant variations in the pyrolysis temperature.

PROCESS TO PRODUCE A PYROLYSIS OIL COMPRISING LIQUID HYDROCARBONS FROM PLASTIC MATERIAL AT HIGH EXERGETIC EFFICIENCY, AND RELATIVE PLANT
Process for producing a pyrolysis oil which comprises liquid hydrocarbons from plastic material, preferably waste material, sustainably. The process is characterized by the use of solar radiation which is used to heat a heat transfer fluid (like molten salts) at multiple temperature levels, so as to use the hotter heat transfer fluid to the pyrolysis devices that require higher temperature. The heat transfer fluid returning from said devices is sent back to the respective solar radiation heaters, thus closing the loops. The process is therefore characterized by having at least two loops of the heat transfer fluid. The plastic material enters a first pyrolysis reactor, heated with a first thermal fluid with molten salts at a moderate temperature, and the gases produced are brought into a second pyrolysis reactor also heated with a second thermal fluid with molten salts, to higher temperature. The particular setup of the process and of the relative plant, which synergistically exploits some specific characteristics of the pyrolysis process and of the solar collectors, allows to obtain a high exergetic efficiency. In particular, the fact that the pyrolysis according to the invention is carried out in two stages is exploited: in a first stage a high amount of energy is required, but at a moderate temperature. Only in the second stage is a high temperature energy source required, which requires a high concentration factor; however, due to the way the pyrolysis process was conceived, the amount of energy required at this stage is minor. This allows to maximize the yield of the process in terms of product obtained (quantity of pyrolysis oil per solar radiation power).

The procedure has the following steps: (A) continuously feeding one or more monomers, one or more solvents in a quantity comprised between 70% and 90% by weight with respect to the reagent mixture, and a catalytic system, to a first stirred reaction volume, wherein a single mixing cell is formed, in which the polymerisation begins, until a conversion is attained that varies from 20% to 70% with respect to the final conversion achieved and (B) proceeding the polymerisation in at least one second stirred reaction volume connected in series to the first reaction volume, in which two or more mixing cells are formed, at the outlet of which the final conversion of the monomer is attained. In the first reaction volume, the average residence time of the reagent mixture varies within an interval ranging from 10% to 25% with respect to the average residence time of the entire reaction volume.
