Industrial Application of LY-2008B/LY-2005C Hydrogenation Catalyst in C5 Hydrogenation Unit of Jilin Petrochemical Company
In allusion to the raw material characteristics(high olefins content)and process conditions of cracking C5 hydrogenation of Jilin Petrochemical Company,two non-noble metal hydrogenation catalysts LY-2008B and LY-2005C were developed and graded proportionally.In September 2021,the first industrial application of the two catalysts was realized in the C5 hydrogenation unit of Jilin Petrochemical Company.At present,the unit operates smoothly,and the bromine valence of the hydrogenation product is concentrated at 10～14 g(Br)·(100 g)-1.So far,the bed pressure difference does not change obviously,indicating that catalysts have excellent activity and coking resistance property.
