PROCESS FOR TREATING CHAR FROM RECYCLED PLASTICS

A process for recovering the carbon contained in a char (solid carbonaceous residue) from a pyrolysis of mixed plastic waste or secondary raw material obtained from the recycling and/or treatment of plastic wastes is described, said process comprising the following steps: (A) heating said char in a gasification reactor and in the presence of carbon dioxide to reach a given temperature comprised in a range lower than 950°C and higher than 600°C, preferably lower than or equal to 850°C; (B) continue heating said char in the aforementioned temperature range, preferably in the range from 750 °C to 850 °C, in the presence of CO2, for a given residence time of said char in said reactor producing an outflow gas stream (effluent) comprising CO in addition to unreacted CO2, and possibly H2, (C) sending at least a part of the gas stream (effluent) leaving the reactor comprising CO, unreacted CO2, and optionally H2, to at least one subsequent operating unit selected from a unit for separating CO from CO2, a direct use unit of said outflow stream or to a storage unit.
