摘要
本试验是采用一种胺类脱金属剂对辽河和委内瑞拉混炼的减压渣油进行金属钒和镍的脱除试验,采用单因素考查适宜的操作条件。结果表明,此种脱金属剂对钒的脱除效果好于镍,其适宜的操作条件为:反应温度170℃,脱金属剂加入量m(剂)/m(油)为3.0%,反应时间20 min和静置时间30 min。钒和镍的脱除率分别为71.56%和35.14%。
This experiment took the vacuum residue oil with the Liaohe and Venezuela oil mixture as raw oil, using esterifiable reagent for the removing of the vanadium and nickel. The optimal operating conditions were determined by using a single-factor method. The results shows that the effect of removing vanadium is better than that of nickel. The optimal condition is： reaction temperature is 170℃, reagent amount is 3.0%, reaction time is 20 vain and settlement time is 30 rain,the removal rates of vanadium and nickel are 71.56% and 35.14% respectively.
