摘    要:为探讨温和条件下油页岩催化萃取技术的可行性,以LiCL为催化剂、CS2-NMP为溶剂,对粒级为0.104mm的油页岩进行催化萃取实验,分析LiCl的添加方式、用量及萃取时间对油页岩溶剂萃取率的影响,确定油页岩催化萃取的最佳工艺条件。结果表明:当油页岩用量为5±0.250g时,萃取开始时即添加LiCl,用量为0.25g,萃取时间为12h,萃取率为13.64%。这比文献3]提高了五个百分点。油页岩原矿、萃余残矿及萃取物的红外光谱(FFIR)分析显示:萃取物中含有大量脂肪族结构和含氧官能团结构的物质,并有少量的芳香类物质;萃余残矿中脂肪族物质以及含氧官能团结构物质相对原矿减少。该研究为油页岩的高效、清洁转化提供了技术参考。

Abstract:This paper, an effort to explore the feasibility of catalytic extraction technology of oil shale under soft-conditions, discusses catalysis and extraction experiments on 0. 104 mm oil shale, conducted using LiC1 as catalyst and CS2 - NMP as solvent and analysis of the influence of LiC1 adding ways, quan- tity and extraction time on extraction rate of oil shale solvent to determine the optimal conditions for cata- lytic extraction process of oil shale. The results show that the extraction rate can be 13.64%, 5% greater than that in ref. 3 ] , when quantity of oil shale is 5 ± 0. 250 g and LiC1 of 0.25 g is added at the begin- ning of extraction and extraction time of 12 h. The results of FTIR on oil shale ore, ore extraction and the extracts of residual present show that extracts contain a large amount of aliphatic structure and oxygen- containing materials and a small amount of aromatic materials. Aliphatic materials and oxygen-containing functional group structure materials in remnant ore are relatively smaller than those in raw material. The study of oil shale efficient and cleaner conversion is a technical reference.
