摘要： The present invention relates to a catalyst composition comprising a modified crystalline aluminosilicate of the Framework Type FER having Si/Al framework molar/ratio greater than 20 characterized in that in said modified crystalline aluminosilicate the ratio between the strong acid sites and the weak acid sites, S/W, is lower than 1.0 and having the extra framework aluminum (EFAL) content lowered to less than 10 wt % preferably 5 wt % even more preferably less than 2 wt % measured by 27Al MAS NMR. The present invention further relates to a process for producing olefins from alcohols in presence of said catalyst composition.

摘要： Isomerizing dehydration of feedstock containing a primary alcohol substituted in position 2 by an alkyl group in which the feedstock is heated to the reaction temperature by indirect heat exchange then vaporization by mixing with a diluent effluent, the diluted and vaporized feedstock being dehydrated in at least one dehydration reactor operating in gas phase at an inlet temperature comprised between 250 and 375° C., at a pressure comprised between 0.2 MPa and 1 MPa and at a WHSV comprised between 1 and 18 h−1, in the presence of a catalyst comprising a zeolite having at least one series of channels the opening of which is defined by a ring with 8 oxygen atoms (8MR) and a binder, the catalyst being coked beforehand in-situ or ex-situ, so as to produce a dehydration effluent, the latter being treated and separated into a diluent effluent, an alkenes effluent and a heavy hydrocarbons effluent.
