HR 845 is a NiMo type catalyst used for the desulfurization of FCC gasoline. It is the catalyst of choice used in Prime-G+ selective hydrogenation technology to eliminate light sulfur compounds from cracked naphthas. It acquires a high level of sulfur removal to meet new motor gasoline specifications. This performance is coupled with complete diolefin removal and very limited olefin hydrogenation. Its unique neutral vehicle provides good stability and long cycles.
