WebThe first step is to hydrotreat the heavy naphtha feed to remove impurities such as sulfur and nitrogen that would be harmful for the reformer's platinum catalysts. This is done in a naphtha hydrotreater that may be considered part of the reformer, or a separate process unit. Next, the feed is sent through a series of 3-4 reactor vessels. WebSteam reforming is the reaction of methane (and other higher hydrocarbons) with steam in the presence of a catalyst to form carbon oxides and hydrogen. Most industrial catalysts are based on using nickel as the catalytic component, although platinum group metals (pgms) are used for some specific duties.
