Abstract
Aspects of the invention relate to producing olefins and other products by oxidative dehydrogenation cracking of a hydrocarbon feed. In one embodiment, the method includes oxidative cracking a hydrocarbon feed comprised of plastic waste. Methods of the present invention employ dual functional catalyst comprising solid acids and metal oxides, which are capable of selectively oxidizing hydrogen to water rather than combustion of the hydrocarbon feeds or products. Additional aspects of the invention demonstrate catalyst synthetic methods for encapsulating metal oxides in the internal channels and cages of solid acids, thereby improving the selective oxidation of hydrogen to water and decreasing feed and product oxidation. The re-oxidation of the thus reduced metal oxide transfer agents supplies heat to drive the endothermic cracking of the feed.
