THHC-I轻油型加氢裂化催化剂的研究开发与工业化生产
Development and industrial production of THHC-I hydrocracking catalyst for producing light fraction
摘要
Abstract
Regarding the prolific reforming raw material technology for the high nitrogen and naphthenic distillate hydrocracking,China National Offshore Oil Corporation(CNOOC)Tianjin Chemical Research & Design Institute Limited Corporation,by modifying the silica alumina ratio of the molecular sieves,the molecular sieves content of the supporter and the metal content of the catalysts,has successfully developed THHC-I hydrocracking catalyst,after pilot preparation,industrial amplification,and industrial production. The THHC-I hydrocracking catalysts for industrial production show the same physical-chemical properties and catalytic performance as the hydrocracking catalysts for pilot preparation and industrial amplification. The 1500h assessment results of the catalyst pilot test for Zhoushan coking heavy distillates show that the conversion of distillate with boiling point>345℃ is 75.8% and the liquid yield of naphtha with boiling point<170℃ is 42.7%. The sulfur and nitrogen content of naphtha are 1μg/g,0.6μg/g respectively. The sulfur and nitrogen content of diesel are 5μg/g, 3μg/g respectively. The assessment results also indicate that THHC-I hydrocracking catalysts show excellent cracking activity,selectivity and stability. THHC-I catalyst has been accomplished 30 tons of production,and successfully applied in the coker heavy distillate hydrocracking using the prolific reforming raw material technology in CNOOC Zhoushan Petrochemical.关键词
