HDAS-20 Reforming pre-dearsenication catalyst
The catalyst is a bifunctional catalyst with good performance.It not only has excellent hydrogenation of arsenic removal and adsorption performance, but also has good organic sulfur hydroconversion abilities, even when arsenic content is to be 17% ,the catalyst still has good hydrodesulfurization activity. We adopt the special process, the catalyst has excellet dearsenication, desulfurization activity of naphtha and other light distillate under the conditions of the space velocity is 12hr-1.
Application: The catalyst is mainly used for dearsenication, desulfurization of light hydrocarbons, such as naphtha, in order to protect subsequent catalyst from poisoning and to some extent mitigate the hydrogenation load.
