Under the severe conditions of bio-oil upgrading in liquid phase, acidic zeolites tend to lose crystallinity. However, the tolerance to hot-liquid water of HY zeolites and stability of the catalytic activity can be greatly improved by hydrophobizing the external surface of the zeolite with organosilanes silylation agents.
