Intellectual Property India Publishes Patent Application for 'Process To Produce A Pyrolysis Oil Comprising Liquid Hydrocarbons From Plastic Material At High Exergetic Efficiency, And Relative Plant' Filed by Versalis S. P. A.

MUMBAI, India, Aug. 29 -- Intellectual Property India has published a patent application (202517072680 A) filed by Versalis S. P. A., Milano, Italy, on July 31, for 'process to produce a pyrolysis oil comprising liquid hydrocarbons from plastic material at high exergetic efficiency, and relative plant.'

Inventor(s) include Felisari, Riccardo; Galeotti, Armando; Santilli, Celeste; and Assandri, Fabio.

The application for the patent was published on Aug. 29, under issue no. 35/2025.

According to the abstract released by the Intellectual Property India: "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 patent application was internationally filed on Jan. 30, 2024, under International application No.PCT/IB2024/050844.
