摘要： A process for steam reforming of hydrocarbons which comprises subjecting a hydrocarbon to steam reforming after desulfurizing the hydrocarbon to a sulfur content of 5 ppb or less. According to the process, a poisoning of steam reforming catalyst by sulfur can be prevented, and stable and economical operation can be attained for a long period.
