固体热载体干馏桦甸油页岩试验研究

设计并搭建了一套处理量为5 kg/h油页岩的回转干馏炉装置，以桦甸油页岩为原料，高温热灰作固体热载体，对该油页岩进行干馏特性试验研究。考察了干馏过程中油页岩出油率的影响因素，经试验发现主要包括固体热载体初温、回转干馏炉转速、固体热载体与油页岩混合比以及油页岩粒径大小。基于上述的实验结果研究了热载体初始温度600℃~800℃、回转干馏炉转速15 r/min~21 r/min、固体热载体与油页岩混合比2~5以及油页岩粒径分布0~5 mm对油页岩出油率的影响。研究结果表明：当固体热载体初温为750℃、回转干馏炉转速为19 r/min、固体热载体与油页岩比例为41及油页岩粒径大小在0~3 mm分布的工况下，油页岩的出油率达到最高，且为95%。

Experimental Investigation of Solid Heat Carrier Retorting of Huadian Oil Shale

A rotary retorting was designed and built used to despoit oil shale 5 kg/h Huadian oil shale, its characteristic retorting was preliminarily observed determined in rotary retorting by solid heat carrier method. The experiment revealed that the influnet factors on oil shale yield were studied in retorting process,such as in-itial temperature of solid heat carrier,speed of rotary retorting,mixing ratio of solid heat carrier and oil shale and particle size of oil shale. Based on the results of above experiments,the paper focused on initial tempera-ture of solid heat carrier from 600℃ ~800℃,speed of rotary retorting 15 r/min~21 r/min,mixing ratio of solid heat carrier and oil shale4 1,particle size 0~3 mm. The results show oil shale yield is highest when ini-tial temperature is about 750 ℃,speed of rotary retorting is about 19r/min,mixing ratio of solid heat carrier and oil shale is about 4 1,particle size is about 0~3 mm,up to 95%.
