Activated carbons prepared with H3PO4 are potential hydrocracking supports.
P-containing activated carbons show stable C–O–PO3 and C–P–O3 acid sites.
Carbon-supported Pt–Pd catalyst is able to remove 90% sulfur and 93 wt% gasoil.
Deactivating coke is deposited on the whole catalytic surface causing pore blockage.
