“…Indeed, in most of the previous works, ZSM-5 (MFI, 10-ring pore system) has been the zeolite of choice as the methanol dehydration component of the bifunctional catalysts [8,9,13,16,24,25,26,27,28,29,30,31,32,33]. Besides MFI, other 10-ring pore structures such as FER (ferrierite) [10,14,34] and MWW (MCM-22, MCM-49) [15,35,36] as well as 12-ring pore systems such as FAU (Y) [13,14,37,38,39,40] and MOR (mordenite) [37,41] have also been studied. Unfortunately, any attempt to gather general conclusions regarding topological effects from the aforementioned studies have been discouraging given the disparity in catalyst composition, preparation method, and reaction conditions.…”
