“…The most used zeolite structure in the catalytic upgrading has so far been the ZSM-5 [7,13,14,[16][17][18][19][21][22][23][24][25][26][27][28][29], some studies have been made with the Y-zeolite [13,16,17,25,27], and some with the beta zeolite [15,16,25,29]. The different structures have different pore size and shape.…”
