摘要: The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with a halogen containing silicon compound selected from the group consisting of halogen containing silanes, halogen containing disilanes, and halogen containing siloxanes. After the metals are contacted with the halogen containing silicon compound, the halogen containing silicon compound is converted to silicon dioxide to form a protective coating on the metals. This protective coating substantially reduces the formation of carbon on metals exposed to hydrocarbons in a thermal cracking process.
摘要翻译: 通过使这些金属与选自含卤素的硅烷,含卤素的二硅烷和含卤素的硅氧烷的含卤素的硅化合物接触来降低在热裂解过程中暴露于烃的金属上的碳的形成。 在金属与含卤素的硅化合物接触之后,将含卤素的硅化合物转化为二氧化硅,以在金属上形成保护涂层。 该保护涂层基本上减少了在热裂解过程中暴露于烃的金属上的碳的形成。

摘要: Metals contained in a hydrocarbon containing feed stream are removed by contacting the hydrocarbon containing feed stream under suitable demetallization conditions with hydrogen and a catalyst composition comprising zirconium phosphate and a metal phosphate where the metal is selected from the group consisting of nickel, iron, vanadium and cobalt. The life and activity of the catalyst composition may be increased by introducing a decomposable metal compound selected from the group consisting of the metals of Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table into the hydrocarbon containing feed stream prior to contacting the hydrocarbon containing feed stream with the catalyst composition.
