A process for the separation of para-xylene |
| abstract |
A process for the separation of para-xylene from a mixture substantially consisting of aromatic hydrocarbons with six to nine carbon atoms in the molecule including para-xylene and ethyl benzene, in which the mixture is contacted with a crystalline silicate with the following overall composition: ny(1.0±0.3)M 2 O.y(a Fe 2 O 3 .b Al 2 O 3 ).SiO 2 nwherein M is H and/or an alkali metal n The crystalline silicate is modified by bringing the crystalline silicate into contact with a solution of a salt of a polyvalent, metal whose metal cation concentration is m (in gion/I) and charge density is (R being expressed in nanometres) and wherein the product = m is at least 45, |
