Abstract:
1. A dehydrogenation catalyst composite comprising: from about 30% by weight to about 98% by weight of alumina; from about 1% by weight to about 40% by weight of chromium oxide, wherein the chromium oxide is derived from a chromium compound that is not or does not contain an alkaline earth chromate; from about 0.1% by weight to about 20% by weight of an alkaline earth metal oxide comprising at least one of barium oxide and strontium oxide; up to about 5% by weight of lithium oxide; and about 0.01% by weight to about 5% by weight of sodium oxide, wherein the chromium oxide and the at least one of barium oxide and strontium oxide are uniformly distributed throughout the dehydrogenation catalyst composite, and wherein the strontium oxide is derived from one or more of the group selected from strontium metal powder, strontium acetate, strontium amide, strontium borates, strontium carbonate, strontium format, strontium halides such as strontium fluoride, strontium chloride, strontium bromide, and strontium iodide, strontium hydride, strontium hydroxide, strontium hypochlorite, strontium nitrate, strontium nitride, strontium phosphate, strontium silicate, strontium zirconate, strontium perchlorate, strontium peroxide, strontium metasilicate, strontium sulfate, strontium monohydrogen orthophosphate, strontium orthophosphate, strontium hypophosphate, strontium pyrophosphate, strontium sulfite, strontium oxalate, strontium citrate, strontium methylate, strontium propylate, strontium pentylate, or strontium ethoxide.
