The understanding of the factors controlling the deposition of carbonaceous solids resulting from the decomposition of hydrocarbons over hot metal surfaces has a considerable impact on a number of commercial processes including, catalytic steam reforming of methane, stem cracking of paraffinic feed stocks and systems involving carbon monoxide disproportionation reactions. The potential for carbon formation exists in any system in which hydrocarbons undergo thermal decomposition and it is well known that certain metals can increase the overall rate of this process by catalyzing the growth of filamentous and graphitic types of deposit. The highest catalytic activity for carbon deposition is exhibited by iron, cobalt and nickel, and alloys containing these metals. In this paper a review of the information obtained from the use of a combination of controlled atmosphere and high resolution transmission electron microscopy techniques to study the dynamics of carbon deposition arising from the metal catalyzed decomposition of hydrocarbons will be presented.
