ADSORPTION OFAROMATIC HYDROCARBON IN LIQUID WAX OIL

Abstract

Abstract: The presence of aromatic hydrocarbon in liquid wax has a serious effect on the quality of downstream products. The separation of the aromatic compounds in liquid wax by adsorption method was studied. The adsorption effect of modified porous carbon, molecular sieve, silica gel and polystyrene resin on aromatic hydrocarbons was investigated, and the structure of the modified adsorbent was characterized. The results showed that the porous carbon material modified with NaOH has a higher specific surface area, the adsorption capacity of aromatic hydrocarbons can reach up to 37.025 mg?g-1, much greater than that of molecular sieve, silica gel and resin. The adsorption performance of the resin is the worst, the adsorption capacity is only 16.025 mg?g-1.

Key words: liquid wax, aromatics, adsorption
