WO3 Hydrodesulfurization Catalyst Prepares Low

The sulfur and thiol contents in cracking Deep Hole Drilling Inserts (FCC) gasoline are respectively 200~1600 ug/g, 30~200 ug/g. FCC gasoline is a major component of some refineries, its mixing ratios can even up to 80% ~ 90%. Therefore, the key to meet the new clean gasoline specifications is to reduce the sulfur content of the FCC gasoline and mercaptans. Hydrodesulfurization catalyst containing tungsten trioxide can be used to handle the full range FCC gasoline to produce low-sulfur gasoline. In which, the gasoline feedstock does not required to fractionate, also the intermediate separation process does not required after RSDS, with the simple process and easy to operate.
