摘　　要：用正交法设计合成实验，用气态鼢磺化胜利炼油厂常压渣油（芳烃含量48．8％，50℃黏度632mPa·s），所得磺化渣油与煤油以质量比10：1混合作为降黏刺，加入实验用胜剞稠油（芳烃含量35．6％，50℃黏度2672mPa·s）中，在70℃加热后降温至50℃测定黏度，计算降黏率，求得磺化渣油作为油溶性稠油降黏刺的最佳合成条件如下：渣油、SO3质量比100：8，反应温度50℃，反应时间90min。此降黏剂代号为YCJ。在实验胜利稠油中，YCJ的降黏率起初随加量增大而增大，加量2、5g／kg时达到最大值-15％，此后持续下降，加量〉5/kg时低于等加量煤油的稀释降黏率。在YCJ中加入煤油可大大提高实验稠油的降黏率，降黏率～加量关系曲线上先后出现最大值和最小值，最大值对于10：1和10：3的YCJ＋煤油分别为36％和52％，对应的加量分别为3和3．5g／kg。将10：3的YCJ＋煤油用于另外5种稠油的降黏，加量3．5g/kg发现高芳烃含量稠油的降黏率也高，降黏率／芳烃含量数据如下：57．2％／34、3％；52．0％／26．3％；34．6％／28、2％；14、5％／19、0％；10．3％／18．1％。图1表3参5。An atmospheric non-distillate of Shengli Oil Refinery containing 48.8% aromatics and having viscosity at 50℃ 0. 632 Pa· s is sulfonated directly by gaseous SO3 in experiments designed orthcgonally; the sulfonated residure is mixed with kerosene in mass ratio 10： 1 and introduced into an experimental heavy oil （EHO） of Shengli containing 35.6% aromatics and having viscosity at 50℃ 2.672 Pa＇s; this mixture is heated at 70℃ and its viscosity is determined at 50℃. According to the percentage viscosity reduction （PVR）, the optimal parameters of synthesizing sulfonated residue as viscosity reducer for heavy oils are estabilished： residue to SO3 mass ratio 100 ： 8, reaction at 50℃ in 90 min. The product obtained is notated as YCJ. In the EHO, the PVR of YCJ increases initially with dosage, reaches a maximum -15% at dosage 2.5 g/kg and then decreases continuously, being less than that of kerosene at equal dosages 〉5 g/kg. YCJ in mixture with kerosene gives much higher PVR in the EHO and PVR vz dosage curves go through a maximum followed by a minimum, the former is of 36% and 52% at dosage 3 and 3.5 g/kg for 10：1 and 10：3 mixture YCJ ＋ kerosene, respectively. For 5 heavy oil other than the EHO, YCJ/kerosene （10 ： 3） mixture at dosage 3.5 g/kg gives higher PVR in heavyoil with higher aromatics content （AC） and following data of PVR/AC are observed： 57.2%/34.3%;52.0%/26.3%; 34.6%/28.2% ;14.5%/19.0% ;10.3%/18.1%.
