However, mercaptan sulfur in DCC gasoline, which has been sweetened at a low operating space velocity and concentrated by solvent extraction, cannot be detected by flame photometer detect. 对脱臭汽油先进行萃取浓缩,再用气相色谱对其进行检测,无硫醇硫存在。

The experimental results show that the distributions of mercaptan sulfur in feed FCC gasoline from several samples are almost similar, and The structure and composition of mercaptan are very complex, and the major mercaptan is butanethiol. 结果表明,不同催化裂化原料的FCC汽油中硫醇的种类和分布大致相同,都存在大量丁硫醇。
Thus, total desulfurization percent of hydrotreated gasoline increases, and mercaptan sulfur content reduces, because of the higher depth of reaction. 通过提高反应深度,加氢汽油总硫的脱除率提高,汽油中硫醇硫含量下降。
According to standard test method of Thiol ( mercaptan) sulfur in liquid petroleum products ( GB/ T1792-88), We estimated uncertainty of the measurement. 根据国家标准GB/T1792-88《馏分燃料中硫醇硫含量测定法(电位滴定法)》的试验方法,考察评估了该项分析的测量不确定度。

The sulfide from oil processing are mainly sulfur dioxide, hydrogen sulfide and mercaptan, and they will accelerate the corrosion to refining unit and increase the pollution risk from emission if sulfur content is high. 石油加工过程产生的主要硫化物有二氧化硫、硫化氢和硫醇,原油中硫含量高,会加快设备的腐蚀,加大了废气污染的风险。
