An improvement was achieved by impregnation of the Y-9 catalyst with rare earth nitrates.The experimental results showed that addition of rare earth oxides in Y-9 catalyst can increase the cracking activity of the catalyst, reduce the amount of carbon daposited on the surface of the catalyst, and accelarate the combustion of deposited Carbon. The crystal planes of the catalyst can be readily restored after combustion of the deposited carbon.
