Area is that aluminum oxide can not be made to have optimal separating effect, and chromatographic silica gel can not be made to reach optimal separating effect；Meanwhile,
In the prior art, to be sequentially filled chromatographic column its length formed in long neck funnel longer for aluminum oxide and chromatographic silica gel, saturated hydrocarbons,
Aromatic hydrocarbon and colloid separation process are time-consuming also longer.
It can thus be seen that there are many defects in the separation method of above-mentioned crude oil group component, therefore, it is necessary to above-mentioned original
The experimental tool of oily Group Component is further improved.
