Industrial Application of SDD-800 Catalyst on Diesel Oil Hydrogenation Unitin Harbin Petrochemical Company

The paper introduces industrial application of SDD-800 catalyst on diesel oil hydrogenation unit in Harbin petrochemical company. The SDD-800 catalyst has good adaptability and selectivity. This catalyst can get better diesel and liquid yield by different operation scheme. SDD-800 catalyst has better stability and against-nitrogen capability, and it brings a long-term running to diesel oil hydrogenation unit based on scheme of lowering pour point. The diesel oil hydrogenation unit will avoid starting and stopping twice every year.
