Abstract
The invention relates to the technical field of asphalt production, in particular to solvent for leaching asphalt oil from carbonaceous asphalt ore. The solvent is prepared from, by volume, 12-16% of ionic liquid, 17-21% of n-hexane, 17-21% of methylbenzene and 42-54% of tetrahydrofuran. By means of the formula, the oil yield can be increased, and unnecessary loss can be reduced.
Description
Technical field
The present invention relates to asphalt production technical field, particularly a kind of solvent leaching asphalt oil for carbenes ore deposit.
Background technology
Carbenes is also known as coaly pitch, pyrobitumen.Pitch earth, asphaltite suffer metamorphic product.Be insoluble to organic solvent, temperature of fusion is higher than 300 DEG C, and relative density 1 ~ 13, hardness 23, black, property is crisp, and large portion is veiny output.Carbenes still can be divided into stellar coal and pyrobitumen two kinds according to metamorphic grade, and the former metamorphic grade is low, flammable, and the latter's metamorphic grade is higher, nonflammable.When utilizing existing solvent to extract the blue or green mineral aggregate of carbenes, efficiency is general not high, and oil yield is not high yet, causes great waste, so design a kind of solvent for petro bitumen ore deposit leaching asphalt oil just seem particularly important.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of solvent for carbenes ore deposit leaching asphalt oil to improve oil yield, reduce unnecessary loss.
For solving above-mentioned technical problem, the invention provides a kind of solvent leaching asphalt oil for carbenes ore deposit, it is characterized in that: comprise following component according to volume percentage: ionic liquid: 12-16%, normal hexane: 17-21%, toluene: 17-21% and tetrahydrofuran (THF): 42-54%.
Further: to comprise following component according to volume percentage: ionic liquid: 12%, normal hexane: 17%, toluene: 17% and tetrahydrofuran (THF): 54%.
Further again: to comprise following component according to volume percentage: ionic liquid: 13%, normal hexane: 18%, toluene: 18% and tetrahydrofuran (THF): 51%.
Further again: to comprise following component according to volume percentage: ionic liquid: 14%, normal hexane: 19%, toluene: 19% and tetrahydrofuran (THF): 48%.
Further again: to comprise following component according to volume percentage: ionic liquid: 15%, normal hexane: 20%, toluene: 20% and tetrahydrofuran (THF): 45%.
Further again: to comprise following component according to volume percentage: ionic liquid: 16%, normal hexane: 21%, toluene: 21% and tetrahydrofuran (THF): 42%.
Further again: described solvent is that described stirring velocity is 20-35r/min by being uniformly mixed rear formation to ionic liquid, toluene, normal hexane and tetrahydrofuran (THF), and during stirring, temperature controls at 22-30 DEG C, and churning time is 30min.
Further again: described ionic liquid is 1-ethyl-3-methylimidazole Si Fu Boron hydrochlorate.
After adopting above-mentioned formula, the present invention improves oil yield by providing a kind of solvent for carbenes ore deposit leaching asphalt oil, reduces unnecessary loss.
