Application of RSDS-1 catalyst for selective hydrodesulfurization

The full-range FCC naphtha selective hydrodesulfurization experiment has been successfully carried out by using RSDS-1 catalyst in the RSDS unit in SINOPEC Changling Company to further study the selective hydrodesulfurization performance of the catalyst.At the operating conditions of 260.1℃average reactor inlet temperature,270.8℃average reactor bed temperature,1.40 MPa reaction pressure,4.25 h~(-1) volumetric hourly space velocity and 422:1 hydrogen to oil volumetric ratio,the sulfur in the FCC naphtha after hydrogenation is reduced to 69 ppm,and the motor octane number(RON) loss is 0.7～2.0 unit,and the gasoline quality meet the EuroⅢstandards specifications.
