摘要: 采用热解法对油田污泥进行处理,通过热解分析及热解放大试验,考察不同温度下热解油收率的变化,并对热解油进行加氢精制研究。结果表明:随着热解温度升高,产油率降低,热解终温以600 ℃较为适宜,产油率为38.61%,产气率为6.52%;热解油的残炭、金属含量、硫含量、氮含量以及沥青质含量均较低;在反应温度为420 ℃、氢分压为12.0 MPa、氢油体积比为800、体积空速为1.0 h-1的条件下,热解油经加氢处理后,脱硫率为94.5%,脱氮率为89.4%,轻油馏分收率较高,可作为轻质燃料调合组分,而蜡油馏分及重油馏分可以作为优质的加氢裂化原料,进而获得更多的轻质燃料。

Abstract: The pyrolytic oils and gases were obtained from oil sludge pyrolysis process at different temperatures and then hydrotreated in pilot scale and scale-up test. The results of pyrolysis experiment show that the oil yield declines as the reaction temperature increases, the oil and gas yield reaches 38.61% and 6.52% at 600 ℃,respectively with small amount of S, N,CCR, metal and asphaltene in the oil. At the hydrotreating conditions of 420 ℃, 12.0 MPa, hydrogen to oil ratio of 800, and space velocity of 1.0 h-1 , the removal rate of sulfur and nitrogen reaches 94.5% and 89.4%, respectively, with high yield of light oil which can be used as a blending component for fuels, while the heavier fraction can be used as hydrocracking feedstocks.
