摘要
以内蒙古苏尼特左旗油页岩为研究对象,采用低温铝甄干馏的方法,对影响其出油率的主要因素进行研究分析,考察了加热速率、干馏终温、持温时间及页岩粒度大小对油页岩出油率的影响。结果表明:加热速率为7℃/min,终温510℃,持温时间25 min且粒径大小约为3 mm的条件下,页岩出油率最高,此时的页岩油出油率为4.42%。
According to Oil Shale of Inner Mongolia Sunith Left Banner, it used methods of terminal temperature of dry distillation to make research and analysis of main factors affect the oil yield, it examined factors of heating rate, retorting the final temperature, retention time and shale particle size. The result showed that under the optimum conditions of the heating rate 7 ℃/min, the terminal temperature 510 ℃ ,the temperature holding time 30min ,the oil shale particle size 3 mm, the yield of shale oil could reach up to 4.42%.
