Abstract:
In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of a reactor is coated with a uniform layer of a ceramic material, the layer being deposited by thermal decomposition of a non-alkoxylated organosilicon precursor in the vapor phase, in a steam containing gas atmosphere in order to form oxide ceramics.

Abstract:
An aluminum nitride ceramic is formed by pyrolyzing a poly-N-alkyliminoalane. A ceramic comprising a solid solution of silicon carbide and aluminum nitride is also formed by mixing a preceramic organosilicon polymer with a polyalkyliminoalane and pyrolyzing the mixed polymers composition to ceramic form.
Process For Providing A Protective Oxide Coating On Ceramic Fibers
Thermally stable ceramic fibers are provided by pyrolysis of organosilicon preceramic polymeric fibers to ceramic form and contacting the ceramic fibers with an oxygen-containing gas so as to oxidize the surface of the fibers and form an in-situ oxide coating.

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

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.
