摘要
A composite adsorbent for separating ethylbenzene from C8 aromatic hydrocarbons by means of adsorptive rectification, comprising 1-50 mass% of a xylene adsorbent and 50-99 mass% of a carrier liquid, wherein the carrier liquid is one or two selected from alkanes, aryl-substituted alkanes, decahydronaphthalene and alkyl-substituted decahydronaphthalene, the alkanes are C10-C26 alkanes, and the aryl-substituted alkanes are C10-C26 aryl-substituted alkanes. The composite adsorbent can improve the volatility of ethylbenzene with respect to other C8 aromatic hydrocarbons, so that high-purity ethylbenzene can be separated from C8 aromatic hydrocarbons by means of adsorptive rectification.
