Solid solution catalyst in particulate form consisting of attrition resistant α-Al 2 O 3 particles with 0.5 to 10% by weight, expressed as the oxide, of iron cations substituted for aluminum cations in said catalyst support stabilized with 0.5 to 10% by weight, expressed as the oxide, of lanthanum and modified with at least two, preferably three, metal cations selected from the metals consisting of chromium, cobalt, magnesium, manganese, and barium; wherein one of said metal cations is barium and said catalyst has X-ray diffraction pattern with peak positions different than that of the α-Al 2 O 3 structure. A process is disclosed which produces ethylene from ethane while producing reduced amounts of vinyl chloride from said ethane to ethylene process. |
