摘要： For a given percentage decomposition, the decomposition temperature of an organosilicon compound is reduced by admixing with the organosilicon compound a decomposition promoting organotin compound. The amount of decomposition promoting organotin compound admixed with the organosilicon compound is sufficient to effectively lower the decomposition temperature of the organosilicon required for a given percentage decomposition.

摘要： The rate of formation of carbon on the surfaces of thermal cracking tubes and the production of carbon monoxide during thermal cracking of hydrocarbons are inhibited by the use of cracking tubes treated with an antifoulant, including tin compound, silicon compound and sulfur compounds in the presence of a reducing gas such as hydrogen. Additionally, the concentration of carbon monoxide in a pyrolytic cracking process product stream is reduced by the treatment of the thermal cracking tubes of such process with a reducing gas having a concentration of a sulfur compound.

摘要： A liquid tin-containing antifoulant composition is injected into a metal-walled thermal cracking reactor tube, concurrently with the injection of a gaseous stream (preferably a steam-diluted C.sub.2 -C.sub.4 alkane stream), through a nozzle of an injection quill which is positioned in the center region of the reactor tube substantially parallel to the flow of the gaseous stream.A liquid tin-containing antifoulant is injected into a metal-walled thermal cracking reactor tube through a nozzle of an injection quill at a temperature of about 1000.degree.-1300.degree. F. while a gaseous stream (preferably a steam-diluted C.sub.2 -C.sub.4 alkane stream) flows through the reactor tube, followed by raising the temperature to about 1400.degree.-1800.degree. F. Preferably, the metal walls of the reactor tube are treated with steam after the antifoulant injection at about 1000.degree.-1300.degree. F. but before the antifoulant injection at about 1400.degree.-1800.degree. F.

摘要： An apparatus for vaporizing volatile liquids comprises a packed column, a gas inlet port (for introducing a hot entrainer gas), a feed tube (for introducing a volatile liquid), a feed distributor comprising a base plate equipped with orifices (through which the liquid flows downward into the packed column) and risers (through which the formed gaseous mixture of entrainer gas and vaporized liquid flows upward), and a gas outlet port. This apparatus can be used to vaporize volatile liquids, preferably volatile tin compounds, optionally in admixture with volatile silicon compounds, wherein steam is used as the entrainer gas.
