Cabral, J A; Coutinho, P H

This invention relates to the production of ethene with a highly profitable yield by means of fluidized bed catalytic cracking of a mixture containing 0.13 to 50 parts by weight of ethanol to 100 parts by weight of hydrocarbons blend at a temperature between 430/sup 0/C and 550/sup 0/C., and pressure between 0 and 5.0kg/cm2 ga in such way that the final gaseous product resulting therefrom has an ethene content between 18.8% and 64% by volume.
