ABSTRACT:
In the thermal cracking of or heating of hydrocarbons, for example naphtha, a carbonization reaction incidentally takes place due to the fact that Ni, Fe and Co contained in, for example, the conduits of the thermal cracking apparatus have a catalytically carbonizing action. The aim of the present invention is to effectively suppress carbon deposition promoted by these elements, to provide for the incorporation of an inhibitor element, e.g. Li, Na, Ba, Be, Ca, Mg or their oxides, into the heat-resistant alloy, and to form on the surface of this alloy a carbon deposition suppressing layer which comprises an inhibitor element.
