文摘Commercial application of the DZC Ⅱ-I catalyst developed on the basis of the DZ-1 catalyst was introduced. The application tests of the catalyst under overload had proved that this catalyst demonstrated satisfactory adaptability to feedstock after continued operation for 20 months with little changes in the bed pressure drop, the reactor inlet temperature and the bed temperature rise. The DZC Ⅱ- 1 catalyst was regarded as the best catalyst for the second-stage hydrogenation of pyrolvsis gasoline.
