The understanding of the factors controlling the deposition of carbonaceous solids resulting from the decomposition of hydrocarbons over metal surfaces has a considerable impact on a number of commercial processes including catalytic steam reforming of methane, steam cracking of paraffinic feedstocks and systems involving CO disproportionation reactions. The potential for carbon formation exists in any system in which hydrocarbons undergo thermal decomposition. It is well known that certain metals can increase the overall carbon yield by catalyzing the growth of both filamentous and graphitic types of deposit. The highest catalytic activity for carbon deposition is exhibited by the ferromagnetic metals and alloys containing these metals. A combination of controlled atmosphere and high resolution electron microscopy techniques have been used to study the formation of the various types of carbon on metal surfaces. The factors controlling both the rate and structural characteristics of the various types of carbon will be discussed.
