摘要： The addition of small amounts of alkaline earth metal oxides (CaO, MgO) as the isomerization function and transition metal oxides (such as MoO3, WO3) as the metathesis function significantly enhances the production of propylene using zeolites. Once the light olefins are formed by cracking on the acid sites of the zeolite, the 1-butene molecules undergo isomerization catalyzed by alkali earth metal oxides and then react with ethylene to produce more propylene.

摘要： A mixed metal oxide Selective Oxygen Carrier (SOC) suitable for the selective oxidation of hydrogen comprising bismuth oxides, rare earth oxides, and a dopant of Ti, Zr, and Hf and is characterizable by a high level of oxygen carrying capacity, selectivity and stability. The SOC can be synthesized using a sol gel procedure, co-precipitating salts, or the incipient wetness method. The invention includes a process of dehydrogenating a paraffin over a SOC. A SOC can also be used to catalytically crack hydrocarbons.
