Abstract
In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of the reactor tubes are coated with a thin layer of a ceramic material, said layer being deposited by thermal decomposition of a non-oxygen containing silicon organometallic precursor in the vapor phase, in an inert or reducing gas atmosphere in order to minimize the formation of oxide ceramics.
