Similarly, hierarchi-cal zeolites can be of a high interest for vegetable oils conversiondue to their enhanced accessibility as a consequence of the presenceof a bimodal porosity, formed by a secondary mesoporosity in addi-tion to the typical zeolitic micropores. The presence of hierarchicalporosity in zeolites usually results in a higher catalytic activity forthe conversion of large compounds, as it is expected to be the caseof triglyceride molecules.
