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．
The effects of basic nitrides on the cracking performance of R F C C feedstocks and the micro-reactivity of the catalysts were studied by adding acid auxiliaries to R F C C feedstocks. Under the conditions of reaction temperature 505 ~ 515 ℃, oil mass ratio 4 ~ 6 and regeneration temperature 690 ~ 710 ℃, the effect of acid additives on catalyst activity, light oil yield , The impact of light oil acid value. The results showed that the activity of the catalyst increased by 3 ~ 4 units when the acid additive was added; when the acid additive mass fraction reached 0. 25% ~ 0. 35%, the yield of light oil can be increased by 3% ~ 4%. At this moment, the content of basic nitrogen in diesel reaches the minimum value; the addition of acid additives does not affect the acid value of gasoline and diesel.
