Ⅰ. Product feature and applied range
FGH-21/31, developed by Dalian Petrochemical Research Institute and produced by Sanju,is a new selective hydrodesulfurization catalyst.
Features:With modified alumina as carrier,carrying molybdenum and cobalt as active component,it has high hydro-desulfurization selectivity and low olefin hydro-saturating activity.It can be regenerated and reused.
Applications:It is specifically used for producing GB-III and GB-IV clean gasoline by OCT-MD technology with FCC gas oil as feedstock.
