Process is provided for producing ethylene by the oxidative dehydrogenation ethane wherein a gas containing ethane is passed to a first elongated reaction zone, and a gas mixture containing oxygen and chlorine is passed into a second elongated gas zone positioned along said first gas zone, said first and second gas zones being separated by a porous member. The pressure of gases within the second gas zone is maintained in excess of the pressure in the first gas zone for diffusion of the chlorine and oxygen through the porous member into the first gas zone. The first gas zone is maintained under conditions sufficient to effect reaction therein of at least a portion of diffused oxygen and chlorine with ethane for production of ethylene. The reaction product containing the desired ethylene is discharged from the first gas zone.
A process for producing ethylene by the oxidative dehydrogenation of ethane which comprises (a) passing a gas containing ethane under pressure into a first elongated gas passage, (b) passing a gas mixture containing chlorine and oxygen under pressure into a second elongated gas passage positioned along said first gas passage, said first and second elongated gas passages being separated by a porous member, (c) maintaining the pressure of the gases in said second gas passage in excess of the pressure in said first gas passage for diffusion of oxygen and chlorine into said first gas passage, (d) maintaining said first gas passage under conditions sufficient to effect the reaction therein of at least a portion of said diffused oxygen and chlorine with ethane for production of ethylene, and (e) withdrawing the gas product containing ethylene from said first gas passage.
