Abstract: The 1.0 Mt/a counter-current CCR unit in CNOOC Taizhou Petrochemical Company was designed with the improved countercurrent moving bed continuous reforming technology. The operation data exhibited good pressure drop distribution and smooth performance. Although the catalyst was slightly poisoned by sulfur and nitrogen and the potential aromatics content of feed was 5.7% lower than the design value，the hydrogen yield reaches 3.53%，the yield of C5+ is 89.63%，the mass fraction of the aromatics in the depentanizer bottom is 77.44% and the catalyst dust is only 3.99 kg/d. The PS-Ⅵ CCR catalyst showed excellent activity，selectivity，and good abrasion resistance and anti-poisoning ability.
