Title
Decane hydroconversion with Al–Zr, Al–Hf, Al–Ce-pillared vermiculites
Abstract

A series of vermiculites pillared with mixed precursors of Al–Zr, Al–Hf and Al–Ce were obtained from natural vermiculite subjected to a process of negative charge reduction through hydrothermal treatment. The catalytic activity of the solids evaluated in the decane hydroconversion, was superior to that of recognized pillared clays and comparable to those of very active catalysts such as zeolites USY. The distributions of profiles of the reaction products suggest that the porosity/pore architecture of the pillared vermiculites should be similar to that of ultrastable Y zeolites.

Graphical abstractVermiculites pillared with Al–Zr, Al–Hf and Al–Ce, obtained from vermiculite submitted to a process of negative charge reduction through hydrothermal treatment, shows catalytic activity in decane hydroconversion superior to others pillared clays and comparable to catalysts such as zeolites USY. Products distribution suggests that the porosity of the pillared vermiculites should be similar to that of USY.Figure optionsDownload full-size imageDownload as PowerPoint slide
