1. A catalyst material, comprising:
molybdenum;
vanadium;
beryllium; and
oxygen,
wherein:
a molar ratio of molybdenum to vanadium is from 1:0.25 to 1:0.65;
a molar ratio of molybdenum to beryllium is from 1:0.25 to 1:0.85; and
oxygen is present at least in an amount to satisfy the valency of any present metal oxides, wherein the catalyst material has a 35% conversion temperature of ethane in a gas stream being converted to a product other than ethane at a weight hourly space velocity (WHSV) of 2.90 h−1, a gas hourly space velocity (GHSV) of 2000 to 3000 h−1, an inlet pressure in a range of 1 pound per square inch gauge (psig) to 2.5 psig, and an outlet pressure in a range of 0 psig to 0.5 psig of from about 300° C. to about 400° C.; and wherein the catalyst material has a selectivity to ethylene of from about 65% to 99% in the oxidative dehydrogenation of ethane at the 35% conversion temperature.
