PROCESS FOR SCAVENGING MERCAPTANS USING A SCAVENGER THAT HAS UNDERGONE A STEP OF CO2 PASSIVATION

The present invention relates to a process for scavenging mercaptans contained in a hydrocarbon-based feedstock containing sulfur, optionally partially desulfurised following a step of catalytic hydrodesulfurisation, at a temperature of between 40°C and 250°C, a pressure of between 0.2 MPa and 5 MPa...

Beschreibung
Zusammenfassung:	The present invention relates to a process for scavenging mercaptans contained in a hydrocarbon-based feedstock containing sulfur, optionally partially desulfurised following a step of catalytic hydrodesulfurisation, at a temperature of between 40°C and 250°C, a pressure of between 0.2 MPa and 5 MPa, at an hourly space velocity, defined as the volumetric flow rate of the incoming feedstock over the volume of scavenger, of between 0.1 h
