  • Patent number: 10421699
    Abstract: Systems and methods are provided for forming alkylate from a tertiary alcohol feed. Olefins for the alkylation reaction can be generated from a portion of the tertiary alcohol feed. The tertiary alcohol feed can be obtained, for example, by selective oxidation to convert a portion of an isoparaffin-containing feed into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate dimerization of the alkenes (e.g. isobutene) to form C8+ olefins (e.g. isooctene). A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

  • Patent number: 9168518
    Abstract: Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst.

    Abstract: Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst.

  • Patent number: 8309780
    Abstract: Provided is a process for oligomerizing n-olefins. The process has the step of reacting (oligomerizing) an amount of one or more n-olefins in the presence of a catalytically effective amount of a two or more metal oxides at a temperature effective to effect oligomerization. The two or more metal oxides are represented by the formula MOn/M?On?. M and M?, are, independently, selected from the group consisting of Al, Ce, Fe, P, W, Zr, and combinations thereof. M and M? are different metals or combinations of metals. “n” and “n?” are positive numbers and vary stoichiometrically depending on the valency of M and M?, respectively. Provided is also a process for alkylation of an alkylatable aromatic compound. The process has the step of contacting an amount of one or more n-olefins with an amount of aromatic compound in the presence of a catalytically effective amount of the two or more metal oxides at a temperature effective to effect alkylation of the aromatic compound.

  • Publication number: 20120283465
    Abstract: The startup of a tubular reactor containing fresh or regenerated molecular sieve catalyst and cooled by steam generation on the shell side, as part of an olefin oligomerisation process, is improved by, during the startup phase of the reactor, controlling the pressure on the shell side of the reactor at maximum 10 barg. The startup may be further improved by controlling the inlet temperature of the hydrocarbon startup stream to the reactor, by controlling the flow of reactant olefins to the reactor, or by controlling the nature and/or concentration of the olefins in the reactor feed.
