采用低温等离子体脱除液化气中的硫醇,考察了停留时间、放电功率、击穿功率等参数对等离子体脱硫的影响。实验发现:但当放电功率过高时,等离子体反应器会产生击穿现象。实验结果表明,低温等离子体可以有效降低液化石油气中硫醇。当放电功率65 W、停留时间为200 s时,液化气的硫醇转化率达到94%以上。 Low temperature plasma was used to remove mercaptan from liquefied gas. Effects of residence time, discharge power and breakdown power on plasma desulfurization were investigated. Experiments found that: when the discharge power is too high, the plasma reactor will have a breakdown phenomenon. The experimental results show that low temperature plasma can effectively reduce the mercaptan in liquefied petroleum gas. When the discharge power is 65 W and the residence time is 200 s, the mercaptan conversion of liquefied gas reaches above 94%.
