摘要
综述了目前多孔炭吸附剂在脱除噻吩类硫化物中的应用，分别介绍了多孔炭及改性多孔炭在吸附脱硫中的应用。重点介绍了改性多孔炭包括氧化改性及金属改性法的活性炭和介孔炭吸附脱硫研究，指出采用氧化一金属复合改性活性炭的方法可显著提高吸附脱硫能力。介孔炭由于具有较高的比表面积、较窄的孔径分布、极好的化学和热稳定性，用在吸附脱硫将可能成为未来的研究热点。
Applications of porous carbon as an adsorbent used for the removal of thiophene sulfides were reviewed, and applications of adsorptive desulfurization by using porous carbon and modified porous carbon were introduced. The research of adsorptive desulfurization modified activated carbon by oxidation and loading metal ions methods, and mesoporous carbon were also introduced in detail.It is suggested that the adsorption capacity of activated carbon was increased efficiently by the oxidation-metal composite modified methods. Mesoporous carbon materials with a high specific area,narrow pore size distribution,excellent chemical, and thermal stability are potentially of great technological interest for adsorptive desulfurization.
