The present invention relates to the redox buffer electro-catalyst for bi-functional air electrode of metal-air batteries and fuel cells, wherein an electro-catalyst comprising of redox buffer oxides facilitates bi-functional activity of air electrode towards oxygen reduction and oxygen evolution reactions at the air electrode-electrolyte interface. The bi-functional activity of electro-catalyst comprising of redox buffer oxides is superior, due to improved electron transfer ability in comparison to electro-catalyst without redox buffer oxides.

The invention relates to a process configuration for production of light olefins and aromatics from residual hydrocarbon streams. In this configuration a high severity catalytic cracking process is employed for producing higher yields of lighter olefins and various boiling fractions. C4 stream separated from gaseous product is subjected to metathesis and aromatized to form mono aromatics.
