Abstract
Disclosed is a method of treating spent equilibrium catalyst (ECAT) for reuse, in which a quantity of spent ECAT comprising hydrophilic particles with differing levels of metal contamination is disposed into a reactor and treated to form carbon nanotubes on the particles having metal contamination, thereby rendering at least a portion of the spent ECAT particles hydrophobic; the hydrophobic particles can then be separated from the hydrophilic particles. Also disclosed is a method of remediating an oil spill using a carbon nanotube sponge material.
