Summary:To provide an economical separation method not requiring input of a large amount of heat, which is a method for separating selectively hydrogen sulfide.SOLUTION: A separation method of hydrogen sulfide has a separation step for bringing gas containing hydrogen sulfide and hydrocarbons into contact with a zeolite membrane having an Si/Al mole ratio which is higher than 1.5 and equal to or lower than 3.0, and having a FAU type crystal phase.SELECTED DRAWING: Figure 1 【課題】硫化水素を選択的に分離するための方法に関するものであって、大量の熱量投入を必要としない経済的な分離方法の提供。【解決手段】硫化水素と炭化水素を含む気体を、１．５より大きく３．０以下のＳｉ／Ａｌモル比を有し、かつ、ＦＡＵ型の結晶相を有するゼオライト膜に接触させる分離工程を有する硫化水素の分離方法。【選択図】図１
