摘要：

We studied the recycling of swelling solution of MWW-type lamellar zeolitic precursor with a Si/Al = 25. Swollen materials were obtained up to a third reuse without any compensation of reactants, pH or decrease of lamellar ordering degree. The pillared material showed a surface area of 777 m(2) g(-1) and mesopores sizes of 2-4 nm characteristic of pillared MWW materials obtained by traditional approaches. (C) 2017 Elsevier Inc.
