New Developments in Ressd Hyclroprocessing

摘要

Heavier feedstocks, and increasingly stringent sulfur specifications lead to laborious operation in resid hydroprocessing units. Asphaltene, in particular, is a dominant component influencing catalyst deactivation, oil stability and sediment formation. It is necessary to treat asphaltene properly to prevent sediment formation and to ensure a longer catalyst life. To meet such requirements, Nippon Ketjen and Akzo Nobel Catalysts have developed new heavy residual oil upgrading catalysts, KFR 22 for fixed-bed, and KF 1312, 1311, 1302T and 1302T2 for ebullated-bed processes. These new products enable better sediment control combined with excellent desulfurization and asphaltene cracking performance.
