研究了油茶果壳活性炭对模拟燃油中二苯并噻吩(DBT)的吸附特性.该活性炭对DBT吸附可在lh达到平衡,吸附动力学行为更符合拟一级动力学模型(R2=0.9572).吸附等温线符合Langmuir模型(R2≥0.9764),室温下最大吸附量为92.76 mg/g.实验条件下苯、甲苯、二甲苯含量在10％时,可使DBT的吸附量从84.58 mg/g分别降至46.53,29.44,23.93 mg/g.该吸附剂吸附DBT具有较好再生性,吸附饱和后材料经甲苯解吸再生5次后,吸附量约降低18％,有望应用于燃油的脱硫处理.“,”In this study,the adsorptive characteristics of dibenzothiophene in simulated fuel by activated carbon derived from Camellia Oleifera Shell (COS) biochar were investigated.Kinetic showed that the adsorption equilibrium could be reached in 1 h.Adsorption kinetic was better fitted with the pseudo-first-order kinetic model (R2 =0.9572).Adsorption isotherm was described by Langmuir isotherm model well (R2 ≥0.9764),and the maximum adsorption amount of DBT was 92.76 mg/g at 298 K.Thermodynamic analysis showed that the adsorption was a spontaneous,exothermic process.Under the experimental conditions,different volume fractions of aromatic hydrocarbons had obvious impact on the adsorption,with maximum adsorption amount decreasing from 84.58 mg/g (without aromatic hydrocarbons) to 46.53,29.44,23.93 mg/g,respectively,when benzene,toluene,xylene of 10％ existed in the samples.Regeneration experiment showed that adsorption capacity of studied activated carbon decreased approximately 18％ after regenerated with toluene for 5 times,which indicated that the activated carbon could be potential adsorbent for the sulfur removal of fuel.
