Provided is a method for suppressing metal corrosion caused by a compound that has an SH structure included in a hydrocarbon, the method including a step for adding, to a hydrocarbon, at least one type of aldehyde selected from a group formed of monoaldehydes having four or more carbon atoms and dialdehydes having three or more carbon atoms. L'invention concerne un procédé qui permet de supprimer la corrosion métallique provoquée par un composé de structure SH contenu par un hydrocarbure, le procédé comprenant une étape consistant à ajouter, à un hydrocarbure, au moins un type d'aldéhyde choisi dans un groupe formé de mono-aldéhydes ayant quatre atomes de carbone ou plus et de di-aldéhydes ayant trois atomes de carbone ou plus. 炭素数４以上のモノアルデヒドおよび炭素数３以上のジアルデヒドからなる群から選択される少なくとも１つのアルデヒドを炭化水素に添加する工程を有する、炭化水素中に含まれるＳＨ構造を有する化合物に起因する金属腐食の抑制方法である。
