✦ Synopsis

Carbon deposits are generally formed during the steamcracking of hydrocarbons. According to the hydrocarbon used, the carbonaceous material can be formed as follows: the initial hydrocarbon reacts in the gas phase: in the case of n hexane, gaseous reactants decompose on the wall of the reactors. The carbonaceous film is smooth and shiny; in the case of cyclohexane and toluene, the gas phase reactions induce the formation of high molecular hydrocarbons which condense in microdroplets which strike the substrat. The microdroplets spread or do not spread, depending on the type of solid sub&rat.
