    摘要: The invention relates to a method for synthesizing a family of zeolite materials, grouped together under the name ITQ-16, in an OHnull medium and in the absence of fluorides and to the catalytic applications thereof. The zeolite ITQ-16 family of materials is characterized by having different proportions of distinct polymorphs A, B and C described as possible intergrowths in the Beta zeolite and, therefore, the X-ray diffraction patterns of said family are different from that described for the Beta zeolite. In its calcinated form, zeolite ITQ-16 has the following empirical formula: x(MXO2):tTO2:gGeO2:(1nullg)SiO2, wherein T is one or more elements having null4 oxidation status and different from Ge and Si; X is one or more elements having null3 oxidation status; and M can be Hnull or one or more inorganic cations with a nulln charge.

    摘要: A process for the alkylation of aromatics with olefins using a solid catalyst is disclosed, wherein the olefin ratio and/or the maximum olefin concentration in the alkylation catalyst bed is maintained less than an upper limit. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. This invention is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.

    摘要: This invention relates to a process for producing zeolite-bound high silica zeolites and the use of the zeolite-bound high silica zeolite produced by the process for hydrocarbon conversion. The process is carried out by forming an extrudable paste comprising a mixture of high silica zeolite in the hydrogen form, water, silica, and optionally an extrusion aid, extruding the extrudable paste to form silica-bound high silica zeolite extrudates, and then converting the silica of the binder to a zeolite binder. The zeolite-bound high silica zeolite produced by the process comprises high silica zeolite crystals that are bound together by zeolite binder crystals. The zeolite-bound high silica zeolite finds particular application in hydrocarbon conversion processes, e.g., catalytic cracking, alkylation, disproportionation of toluene, isomerization, and transalkylation reactions.

    摘要: The alkylation of benzene-containing feedstock over a zeolite beta alkylation catalyst which is formulated with a silica binder and has an average regeneration coefficient of at least 95% for at least three regenerations. The alkylation reaction is carried out in the liquid phase or supercritical region with a C2-C4 alkylating agent, specifically ethylene. The catalyst exhibits a regeneration coefficient of at least 95% after ethylation of the benzene with ethylene at a benzene/ethylene mole ratio of less than 10. The ethylation of benzene occurs at an initial designated primary activity. The operation of the reaction zone is continued until the activity of the catalyst for the ethylation of benzene decreases by a value of at least 0. 1% and not more 1% from the initial designated primary activity. The operation of the reaction for alkylation is terminated and a regeneration procedure is instituted in which the catalyst is regenerated in an oxidizing environment at an average temperature of no more than 500null C. At the conclusion of the regeneration procedure, the operation of the alkylation zone is reinstituted with the reaction zone again operated under conditions as described above followed by regeneration.
