Investigation on dissolution behavior of Huadian oil shale in two stage extraction
摘要
Abstract
The oil shale from Huadian,Jilin was taken as research object,and extraction with dichloromethane and petroleum ether was conducted at two stages. SEM pictures of untreated oil shale and two stage extraction residue were taken,and dichloromethane and petroleum ether raffinate were analyzed with GC/MS. The dissolution behavior of Huadian oil shale in these two extractants and surface morphology of extraction residue were studied. With dual-stage extraction,relatively smooth lamellar structure of oil shale particles gradually disappeared,particle size tended to be smaller,particle surface became more uneven,and liquid-solid contact area increased. Dichloromethane and petroleum ether were able to dissolve paraffinic hydrocarbons in oil shale. The major components of extract were C15 to C28 saturated alkanes. Solvent extraction could effectively extract a class of or similar compounds from oil shale. Oil shale extraction is significant to studying composition of oil shale and extracting the components of high economic value.关键词
