“…Instead of using Cr, other metal chlorides such as the low cost, extensively available, and non toxic FeCl 3 [24] can be considered. Thus, Fe modified zeolite (Fe/HY zeolite) was prepared and applied as catalyst for glucose conversion to LA [25]. The Fe/HY zeolite catalyst was found to be active and reusable for LA production.…”

“…Os picos de difração observados podem ser atribuídos a estrutura do tipo FAU da zeólita HY, caracterizada por reflexões intensas em 2θ igual a 6,4°, 23,76° e 15,78°, conforme descritos na literatura [12] e [13]. Os demais picos presentes também são atribuídos a zeólita com estrutura do tipo FAU e com alto grau de pureza.…”

ResumoO objetivo deste trabalho foi estudar a síntese e caracterização de catalisadores micro-mesoporosos visando sua aplicação em processos de craqueamento realizado em leito fluidizado (FCC -Fluid Catalytic Cracking). Catalisadores micro-mesoporosos do tipo HY/MCM-48 em três proporções foram sintetizados através do método de mecanossíntese. Os catalisadores foram caracterizados por difração de raios-X e adsorção de N2 a 77 K. Os difratogramas de raios-X indicaram que os catalisadores sintetizados apresentam os picos característicos da estrutura microporosa (zeólita HY) e da estrutura mesoporosa (MCM-48), mantendo assim as estruturas micro e mesoporosas após os procedimentos de síntese. As análises por adsorção de N2 revelaram que os materiais apresentaram expressivos valores de áreas superficiais específicas na faixa de 1100 a 2000 m 2 g -1 e volume de poros na faixa de 0,26 a 0,78 cm 3 g -1 . AbstractThe aim of this work was to study the synthesis and characterization of micro-mesoporous catalysts for potential application in fluidized bed catalytic cracking processes (FCC -Fluid Catalytic Cracking). Micromesoporous catalysts of HY/MCM -48 type at three different ratios were synthesized via mechanical synthesis method. The catalysts were characterized by X-ray diffraction and N2 adsorption at 77 K. The Xray diffractograms indicated that the synthesized catalysts show characteristic peaks of the microporous structure (HY zeolite) and the mesoporous structure (MCM-48), thus maintaining the micro and mesoporous structures after the procedures of synthesis. The analysis by N2 adsorption showed that the materials have expressive values of specific surface areas in the range 1100 to 2000 m 2 g -1 and a pore volume in the range 0,26 to 0,78 cm 3 g -1 .

“…In our previous study, Fe/HY zeolite catalyst has been tested for glucose conversion to LA (Ramli & Amin 2015 The Fe/HY zeolite was prepared using wetness impregnation method, with 10% weight ratio of FeCl 3 to the HY zeolite (Ramli & Amin 2015). Fe/HY zeolite and parent HY zeolite were characterized using several methods.…”
