- 摘要:
- 在中海油气（泰州）石化有限公司100万t/a连续重整装置石脑油加氢精制预处理单元考察了DN-3630催化剂的工业应用情况，并与原使用F系列催化剂进行对比。结果表明：DN-3630具有高活性、高选择性，加氢精制油收率比F系列催化剂的增加4.74个百分点，对长链烷烃具有选择性裂解与异构特性，C11烷烃转化率达19.05%；DN-3630具有寿命长、热稳定性好、催化剂结焦速度慢等优点，在6 a的运行时间内，反应器床层温升平均值为6.02 ℃，脱氮率达到100%，比F系列催化剂提高20.96个百分点；在非必要停止压缩机运行的检修过程中，保持气体流动，能够有效降低加热炉管内壁结焦物的脱落，避免催化剂床层压降上升。
- Abstract:
- The industrial application of DN-3630 catalyst was investigated in the hydrogenation refining pretreatment unit of 1 Mt/a continuous reforming unit of Taizhou Petrochemical Co Ltd of CNOOC， and compared with original used F-series catalyst. The results showed that DN-3630 had high activity and selectivity.The yield of refined oil was increased by 4.74 percentage point compared with F-series catalyst. It exhibited selective cracking and isomerization characteristics for long-chain alkane， and conversion rate of C11 alkane was 19.05%. DN-3630 had advantages of long life， good thermal stability， and slow catalyst coking rate. Within 6 a of operation， the average temperature rise of reactor bed was 6.02 ℃， and denitrification rate reached 100%， which was 20.96 percentage points higher than that of F-series catalyst. During checking compressor under non essential shutdown， it could reduce detachment of coking materials effectively on the inner wall of heating furnace tube when maintaining gas flow， and avoid an increase in pressure drop of catalyst bed.
