The removal of dibenzothiophene (DBT) in a hydrocarbon liquid model fuel (MF) by Ni-loaded carbon (Ni/C) prepared from lignite has been studied with a flow-type fixed-bed reactor. The performance of Ni/C in the removal of 500 ppmw S in MF depends on the amount of Ni loaded. The highest ability is observed at 11 wt % dry Ni under the conditions of a reduction time of 0.5 h and a desulfurization temperature of 200 °C. In addition, the reduction time influences the breakthrough curves, and it is found that the optimum condition for DBT removal from MF by Ni/C is 1.0 h. When the desulfurization temperature for evaluating the DBT removal ability of Ni/C is increased, the breakthrough and saturation points also increase, and the greatest performance is observed at 200 °C. From the identification of MF treated by Ni/C, it was found that a part of DBT in the MF feed is removed by chemical adsorption via cleavage of the C–S bond in the DBT molecule to form biphenyl which can adsorb onto a carbonaceous material surface.

褐煤制取镍载碳对液态烃类燃料中有机硫的去除

利用流动型固定床反应器研究了用褐煤制取的含镍碳（Ni / C）去除烃类液体燃料（MF）中的二苯并噻吩（DBT）的方法。Ni / C去除MF中的500 ppmw S的性能取决于负载的Ni量。在还原时间为0.5小时和脱硫温度为200°C的条件下，以11 wt％的干燥Ni观察到了最高的能力。此外，还原时间会影响穿透曲线，并且发现通过Ni / C从MF中除去DBT的最佳条件为1.0 h。当用于评估Ni / C的DBT去除能力的脱硫温度增加时，穿透点和饱和点也增加，并且在200°C时观察到最大的性能。通过Ni / C处理的MF的鉴定，
