Production Of Paving Asphalts From High-Wax Crude Oils

摘要

High-quality BND 40/60 and BND 60/90 asphalts were made from high-wax Kotur-Tepe crudes with additives - heavy catalytic gasoil,hard asphalt from propane deasphalting,and extracts from selective treatment of oil feedstock - were manufactured in pilot conditions.Production of such asphalts by direct oxidation of vacuum resid is not possible.Optimum feedstock compositions are proposed.paving asphalts,group hydrocarbon composition,waxy crudes,pilot unit,aromatic additives,hard asphalt,oxidation,compounding.
