Description
(1)保水率50〜70%の活性炭に、よう化カリウムを活性炭100部に対して35〜65重量部添着させてなる液状炭化水素中の水銀又は水銀化合物除去用活性炭、(2)水銀又は水銀化合物を含有する液状炭化水素に上記(1)の活性炭を接触させる液状炭化水素中の水銀又は水銀化合物の除去方法、および
(3)保水率50〜70%の活性炭とよう化カリウムの水溶液を混合し、活性炭100重量部に対して35〜65重量部のよう化カリウムを添着させ、乾燥する液状炭化水素中の水銀又は水銀化合物除去用活性炭の製造法、
である。
保水率(%)={(W-W0)/W}×100(%)
賦活された原料活性炭の液状窒素中での窒素吸着等温線からCI法により求めた細孔容積は、0.3〜2.0 ml/g、好ましくは0.5〜1.8 ml/g、さらに好ましくは0.6〜1.5 ml/gである。

[比較例2]
[水銀平衡吸着実験]
また、本発明のいずれの活性炭(添着活性炭No.1〜4)およびNo.5の添着活性炭は、活性炭からのよう化カリウムの溶出は認められず、天然ガスコンデンセートの性能を損なう懸念がないことが確認されたが、比較例のNo.6の添着活性炭は僅かながらよう化カリウムが検出された。
[液状炭化水素中の水銀除去実験]
よう化カリウム添着活性炭No.1からNo.6について、活性炭処理後の天然ガスコンデンセート中の水銀濃度が10μg/Lになるまでの処理日数を比較した。結果を表2に示した。
