The separated island form method of aromatic hydrocarbons and sulfur-bearing aromatic hydrocarbons in heavy oil aromatic component

The separation method of aromatic hydrocarbons and sulfur-bearing aromatic hydrocarbons in a kind of heavy oil aromatic component, comprise and be separated aromatic component from heavy oil, the aromatic component unreactive hydrocarbons obtained are dissolved, add in the solid-phase extraction column of filling Stationary liquid again, the aromatic hydrocarbons rinsing Stationary liquid absorption with weak polar solvent must containing the eluent of aromatic hydrocarbons, the eluent of sulfur-bearing aromatic hydrocarbons must be contained again with the sulfur-bearing aromatic hydrocarbons of intensive polar solvent flushing Stationary liquid absorption, solvent in eluent is steamed except obtaining aromatic component and sulfur-bearing aromatic component, described Stationary liquid is the aluminium oxide of load palladium bichloride or the potpourri of aluminium oxide and silicon dioxide, in Stationary liquid, palladium bichloride content is 3 ~ 10 quality %.This method can aromatic hydrocarbons effectively in heavy oil separation aromatic component and sulfur-bearing aromatic hydrocarbons, simple to operate, convenient and swift.Aromatic component and sulfur-bearing aromatic component can use field desorptiion/lonization-Time of Flight to measure type of compounds wherein and carbon number distribution.
