Abstract
A process and apparatus for steam reforming of hydrocarbons. Heat from a product stream of reformed gas is utilized to supply heat required for endothermic reforming of a process gas of hydrocarbons and steam by indirect heat exchange between the product stream and process gas. The temperature of metallic materials of gas heated reactors used in the reforming is controlled so as to avoid metal dusting on tube walls of the gas heated reactors.
