温和条件下煤中有机硫的脱除

摘要

The effects of CH3I on the removal of organic sulfur from coalunder the mild conditions of ultrasonic irradiation or thermal treatment were investigated. The synergic effect of CH3I and CH3OH on the removal of organic sulfur from coal was also observed. The removal yield of organic sulfur from coal increased with the increase in dosage of CH3I and the time of thermal treatment. The organic sulfur compounds removed from coal were identified by GC/MS.%在超声波辐射或热处理条件下，考察碘甲烷对煤中有机硫的脱除效果，对碘甲烷和甲醇在煤中有机硫的脱除过程中的协同作用也进行了考察。随着碘甲烷用量的增加和加热时间的延长，有机硫的脱除率也随之增加。用GC/MS对脱除下来的有机硫化合物进行了检测。
