摘要

"Layer of molecular sieve crystal, process for the production of a layer of crystalline molecular sieve.Process to enhance the selectivity of a crystalline molecular sieve layer, process for separation of at least one component of a flow of hydrocarbon, and,Process for the separation of para xylene.A process is described for the production of layers of crystalline molecular sieve with good performances and seletividades of para xylene of good selectivity of para xylene on meta xylene.The process requires impregnation of the support prior to the synthesis ludrotu00e9rmica using the method of seed and can be performed with mascaragem pre impregnation.The layer of crystalline molecular sieve has a selectivity ( 244 ~ x ~) to para xylene on meta xylene, 2 or more and a performance of (Q ~ x ~) to para xylene, 3.27 x 10 ^ - 8 ^ moles (PX) / m ^ 2 ^. S.pa (PX) or more measured at a temperature of 250 242 198 C and a partial pressure of aromatic hydrocarbon of 242 10 x 10 ^ 3 ^ pa.
