The hydro - demetallization kinetic model and the expression of catalyst deactivation function were proposed on the base of appropriate hypothesis used in common kinetic research methods and the operation data from maoming ' s residue hydrodesulfurization treatment unit ( s - rht ) 摘要依据茂名渣油加氢工业装置( s - rht )的大量实测数据,通过合理的模型假定,采用常规的动力学模型研究方法,建立了渣油加氢脱金属动力学模型和催化剂失活函数表达式。
