【摘要】 <正> 以磺化酞菁钴为催化剂的催化氧化法脱除汽油中的硫醇前已报导。所采用的方法是液—液法,脱臭效果是满意的。对于煤油镏份,用液—液法难以将其中的硫醇除去,一般采用固定床法。固定床所用的吸附剂(或催化剂)有分子筛,离子交换树脂,磺化酞菁更多还原

【Abstract】 A process for treating sour kerosene is proposed. The kerosene mixed with air is passed through a fixed bed of charcoal supported cobalt phthalocya-nine catalyst in an alkaline environment at a liquid hourly space velocity of 3, resulting in the oxidation of mercaptans to disulfides. This treatment can reduce mercaptan content from 345 ppm to 16 ppm. Prewashing of kerosene with a dilute sodium hydroxide solution may increase the catalyst life. Regeneration of catalyst is effected by blowing air at 400℃ for 3 hours. Preparation of the said catalyst is also presented.更多还原
