摘要：

A new technique for the measurement of the growth of the surface deposit of carbon during pyrolysis has been used in conjunction with analysis of products to relate carbon formation to formation of hydrocarbon products in the pyrolysis of methane. The method involves the measurement of the absorbance of the carbon deposit formed on the surface of the vessel during pyrolysis using a He-Ne laser as the analyzing beam. It is shown that the aromatic hydrocarbon products grow exponentially with the number of carbon atoms in the molecule and that molecules sufficiently large to condense to liquid droplets in the reaction vessel may form during the induction period for carbon formation. The kinetics and mechanism of the reaction are discussed. © 1979.
