Abstract (en)
1. A process for treating carbon-bearing organic wastes of synthetic or predominantly synthetic origin, with hydrogen and/or hydrogen-bearing gases and/or hydrogen-transferring solvents, possibly in the presence of a catalyst or catalysts, characterised in that : a) the treatment is carried out at a temperature of from 200 to 600 degrees C, preferably from 200 to 540 degrees C and particularity preferably from 300 to 540 degrees C, under a pressure of from 30 to 500 bars, preferably from 50 to 450 bars and particularity preferably from 50 to 350 bars and for a residence time of from 1 minute to 8 hours, preferably 10 minutes to 6 hours and particular preferably from 15 minutes to 4 hours, and b) the carbon-bearing organic wastes of synthetic or predominantly synthetic origin are at least partially subjected to a preliminary treatment in hydrogen and/or hydrogen-bearing gases and/or hydrogen-transferring solvents, at a temperature of from 75 to 600 degrees C, preferably from 75 to 540 degrees C and particular preferably from 120 to 500 degrees C, under a pressure of from 1 to 600 bars, preferably from 1 to 500 bars and particular preferably from 1 to 350 bars, and for a residence time of from 1 minute to 6 hours, preferably from 1 minute to 4 hours, and/or are at least in part subjected to a preliminary treatment in an inert atmosphere at a temperature of from 75 to 600 degrees C, preferably from 75 to 500 degrees C, particulary preferably from 120 to 475 degrees C, under a pressure of from 1 to 600 bars, preferably from 1 to 500 bars and particular preferably from 1 to 350 bars, and for a residence time of from 1 minute to 6 hours, preferably from 1 minute to 4 hours.
