The hydrocracking abilities of mesoporous MCM-41 materials were studied using 1,3,5-triisopropylbenzene (1,3,5-TiPB) cracking as test reaction. Various MCM-41 samples with varied Si/Al ratios (15 to ∞) and pore sizes (1.57 to 3.04 nm), synthesized by the 'delayed neutralization' method, were examined. It is concluded that 1,3,5-TiPB cracking reaction over Al-MCM-41 is diffusion controlled and coking is responsible for catalyst deactivation. The roles of Al content and pore size on the catalytic features of the samples were evaluated by the conversion of 1,3,5-TiPB, coke content and deactivation parameters.
