Abstract: | The industrial application of semi-regenerative reforming catalyst PRT-C/PRT-D developed by SINOPEC Research Institute of Petroleum Processing in a 500kt/a catalytic reforming unit of Dushanzi Petrochemical Company of PetroChina was introduced. After 1 263 days long-term operation in the first cycle of PRT-C/PRT-D, using the feed with aromatics potential content of 52.30%, under the reaction conditions of space velocity of 1.04 h-1 and a weighted average bed temperature of 452.9 ℃, the stable gasoline yield was 87.12%, the aromatics yield was 57.93%, and the total pressure drop of the reactor was only 44.9 kPa. After the first off-site regeneration, the PRT-C/PRT-D catalyst had been operated for 1 474 d in the second cycle. Using the feed with aromatics potential content of 49.40%, under the reaction conditions of a weighted average bed temperature of 461.6 ℃ and a space velocity of 1.38 h-1, the yield of gasoline was 91.00%, the aromatics yield was 59.33%, and the total pressure drop of the reactor was only 53.1 kPa. The catalyst showed good regeneration performance, good activity, selectivity and stability. |
