〈発明の効果〉
本発明方法は、炭化水素系油と銀担持活性炭を固−液接
触して、炭化水素系油中の水銀を除去するので、炭化水
素系油中に混在する水銀が選択的に効率良く除去でき、
しかも処理後の精製物の分離が容易である。<Effects of the Invention> The method of the present invention brings hydrocarbon oil and silver-supported activated carbon into solid-liquid contact to remove mercury from the hydrocarbon oil, so mercury mixed in the hydrocarbon oil is selectively removed. can be removed efficiently,
Moreover, it is easy to separate the purified product after treatment.
水銀を除去された炭化水素系油は、触媒被毒成分を含ま
ないので、水添反応等の触媒使用反応に広く利用できる
。Hydrocarbon oils from which mercury has been removed do not contain catalyst-poisoning components, so they can be widely used in reactions that use catalysts, such as hydrogenation reactions.
