摘要： The invention relates to a method of preparing an alkylated aromatic compound. The inventive method is characterized in that it comprises an alkylation reaction of an aromatic compound with an alkylating agent which is selected from an olefin, an alcohol and a polyalkylated aromatic compound, in the presence of a catalyst which is a porous crystalline material with the following chemical composition in the calcined form: X2O3:n YO2:m ZO2, wherein (n+m) is at least 5, X is at least a trivalent element, Z is Ge, Y is at least a tetravalent element different from Ge and the n/m ratio is at least 1. Said method is particularly suitable for obtaining cumene.

摘要： The invention relates to a method of separating the components of a mixture. The inventive method is characterised in that it comprises the following steps: (a) the bringing into contact of the components of a mixture selected from (i) at least two hydrocarbons, (ii) a mixture containing at least nitrogen and oxygen, and (iii) at least one hydrocarbon and water, with an ITQ-29 zeolite material having a T(IV)/T(III) ratio of greater than 7, whereby T(IV) denotes one or more tetravalent elements and T(III) denotes one or more trivalent elements; (b) preferential adsorption of one or more of the components by the ITQ-29 zeolite material and (c) recovery of one or more of the components, preferably for the separation of hydrocarbon mixtures, such as linear or branched olefins from paraffins.
