【摘要】 碱性氮化物影响 Ｒ Ｆ Ｃ Ｃ 原料油的裂化性能及催化剂的微反活性，采用在 Ｒ Ｆ Ｃ Ｃ 原料中加入酸性助剂的方法，进行了提高轻油收率的研究． 在小型同轴试验装置上，反应温度为５０５ ～５１５ ℃， 剂油质量比为４ ～６ ，再生温度为６９０ ～７１０ ℃的条件下，分别考察了酸性助剂对催化剂活性、轻油收率、轻油酸值的影响． 结果表明：加入酸性助剂后， 催化剂活性提高了３ ～４ 个单位；当酸性助剂质量分数达到０ ．２５ ％ ～０ ．３５ ％ 时，轻油收率可提高３ ％ ～４ ％ ，此时，柴油中碱氮的质量分数达到最小值；酸性助剂的加入不影响汽油与柴油的酸值．更多还原

【Abstract】 Aiming at the miniactivity of catalysts and the properties of feedstocks affected by basic nitrogen, adding acid additives into the feedstocks of RFCC, a test was accomplished on a small unit to inspect the effect at the conditions:reaction temperature 505～515 ℃,cat./oil=4～6,regeneration temperature 690～710 ℃. The result shows that the activity of catalyst was improved 3～4 unit,the yield of light oil was improved by 3%～4% when w(acid additives)=0.25%～0.35%,at the same time the basic nitrogen content of diesel was minimum. The acid additives did not affect acid value of light oil.更多还原
