Abstract: In order to further understand the performance of running, analysis and forecast ofhainanrefining &chemical Co. Ltd. SINOPEC 2.48Mt / a diesel hydro-upgrading MHUG-Ⅱ,it products to meet the Ⅳand V clean diesel long-term operation. Go into operation to June 30,2015,product Ⅳ accumulated 479 days, V diesel accumulated 146 days. Operation analysis shows that the reactorof hydro-upgrading and reforming catalyst deactivation average rate was 0.015℃/d and 0.042℃/d, refining reactor catalyst deactivation average rate was 0.055℃/d, two reactors total pressure drop rise a rate of 6.4×10-4MPa/d. At the same time considering the nature of raw materials and processing changes in the proportion, the product Ⅳ&V rotation effect the catalyst life and reactor pressure drop. To predict the refining reactor catalyst then run 620 days to reach the regeneration cycle or exchange.

Key words: diesel hydro-upgrading, MHUG-Ⅱ, catalyst, predict prediction
