In reactions involving bulky molecu

In reactions involving bulky molecules, such as triglycerides conversion, catalyst accessibility and textural properties have a strong effect on the overall catalytic performance as the latter maysuffer from steric and diffusion limitations. Conventional zeolites,having micrometer crystal sizes, present a low accessibility of bulky molecules to the active sites since most of them are located within the micropores. For that reason, several works have been reportedin the last years focused on the conversion of vegetable oils using ordered mesoporous materials
