摘要： An aromatic-hydrocarbon solvent is utilized to purge contaminants, such as sulfur, from a conversion system. Complementary contaminant-removal steps may include oxidation, reduction, and contaminant removal with a sacrificial particulate bed. This solvent purge avoids deactivation of a subsequently loaded contaminant-sensitive catalyst, such as a reforming catalyst selective for dehydrocyclization.
