摘要
在传统催化重整装置预加氢催化剂的制备工艺中,通常采用的硫化剂存在易燃、易爆和恶臭等问题。在中国石化济南分公司600 kt/a逆流移动床连续重整装置中,首次采用新型环保型硫化剂SZ-54制备预加氢催化剂,并且介绍了装置硫化工艺参数。应用结果表明:SZ-54硫化剂具有良好的操作安全性及低温分解性;硫化过程中装置现场无明显异味,体现出良好的环保效益;经硫化后的预加氢催化剂表现出良好的活性及选择性。
In the conventional catalytic reforming plant pre- hydrogenation catalyst preparation process, the usually used vulcanizing agent has flammable, explo- sive and odor problems. In the 600 kt/a countercur- rent moving bed continuous reforming unit of SIN- OPEC Jinan Branch, the pre- hydrogenation catalyst was prepared by using the new environment -fi＇iendly vulcanizing agent SZ -54 for the first time, and the vulcanization process parameters were introduced. The results show that the SZ -54 vulcanizing agent has good operational safety and low temperature de- composition. The vulcanization process has no obvi- ous odor at the site, and it has good environmental benefits. The pre -hydrogenation catalyst after vul- canization shows good activity and selectivity.
