In reactions involving bulky molecules, such as triglyceridesconversion, catalyst accessibility and textural properties have astrong 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 bulkymolecules to the active sites since most of them are located withinthe micropores. For that reason, several works have been reportedin the last years focused on the conversion of vegetable oils usingordered mesoporous materials
