摘要： Oligomer products are produced by reacting an alpha olefin and a vinylidene compound in the presence of a solid catalyst, such as a solid oxide or a chemically-treated solid oxide. Metallocene compounds, organoaluminum compounds, and BF3 are not needed to perform the reaction. Oligomer products formed by processes disclosed herein have a trimer:tetramer weight ratio of at least 2:1.

摘要： The present invention relates to catalysts, more particularly to a cobalt-containing catalyst composition. The present invention further relates to a process for preparing a cobalt-containing catalyst precursor, a process for preparing a cobalt-containing catalyst, and a hydrocarbon synthesis process wherein such a catalyst is used. According to a first aspect of the invention, there is provided a cobalt-containing catalyst composition comprising cobalt and/or a cobalt compound supported on and/or in a silica (SiO2) catalyst support wherein the average pore diameter of the catalyst support is more than 20 nm but less than 50 nm; the catalyst composition also including a titanium compound on and/or in the catalyst support, and a manganese compound on and/or in the catalyst support.

摘要： Oligomerization catalyst and method for oligomerization using the catalyst. The catalyst comprises a single Zn(II) or Ga(III) metal ion center directly bonded to a support through a shared oxygen atom, the catalyst having at least one M-O bond which forms an active site for oligomerization. The method includes reacting one or more C2 to C12 olefins with the oligomerization catalyst at a temperature of about 200° C. or higher to provide an oligomer product comprising C4 to C26 olefins.

摘要： The present invention discloses processes for oligomerizing an olefin feedstock containing C4 to C20 alpha olefins using a catalyst system containing a metallocene compound, an organoaluminum compound, and a suspension of a chemically-treated solid oxide. The liquid medium for the suspension of the chemically-treated solid oxide can be an alpha-olefin oligomer product formed by the oligomerization process.

摘要： Embodiments of processes and multiple-stage catalyst systems for producing propylene comprising introducing a hydrocarbon stream comprising 2-butene to an isomerization catalyst zone to isomerize the 2-butene to 1-butene, passing the 2-butene and 1-butene to a metathesis catalyst zone to cross-metathesize the 2-butene and 1-butene into a metathesis product stream comprising propylene and C4-C6 olefins, and cracking the metathesis product stream in a catalyst cracking zone to produce propylene. The isomerization catalyst zone comprises a silica-alumina catalyst with a ratio by weight of alumina to silica from 1:99 to 20:80. The metathesis catalyst comprises a mesoporous silica catalyst support impregnated with metal oxide. The catalyst cracking zone comprises a mordenite framework inverted (MFI) structured silica catalyst.

摘要： Oligomerization processes include the steps of introducing a monomer containing a C3 to C30 olefin and a chemically-treated solid oxide into a reaction zone, and oligomerizing the monomer to form an oligomer product in the reaction zone. Fluorided silica-coated alumina and fluorided-chlorided silica-coated alumina are illustrative chemically-treated solid oxides that can be used in the oligomerization processes.
