本文研究了神华煤在中温（低于160 °C）下预溶胀处理对其加氢液化性能的影响。结果表明，在四氢萘（THN）中，随着预溶胀温度的升高，煤的液化转化率逐渐升高，直至120 °C。而以N-甲基-2-吡咯烷酮（NMP）为溶胀剂时，液化转化率随预溶胀温度的升高而降低。液化产物分布与预溶胀预处理条件密切相关，并对其机理进行了探讨。在此基础上，提出了一种提高液化转化率和油气产率的膨胀液化联合工艺。
The effects of pre-swelling treatment of Shenhua coal at mild temperatures (less than 160 °C) on its hydro-liquefaction properties were determined in this paper. It was found that with the increase of pre-swelling temperature in tetralin (THN) up to 120 °C, the liquefaction conversions of swollen coals increased. However, when N-methyl-2-pyrrolidinone (NMP) was used as swelling solvent, the liquefaction conversion decreased with the increase of pre-swelling temperature. The liquefied product distributions were very much dependent on the pre-swelling pretreatment conditions, and the mechanism was discussed. Based on the results obtained, a new swelling-liquefaction combining technology (SLCT) was advanced, in which the liquefaction conversion and oil+gas yield were enhanced.
