High yield of light olefins by catalytic pyrolysis of naphtha on spinel-based catalysts is reported. The yields of ethylene and propylene reach over 50% and are at least 10% and 5% higher respectively than the yield using thermal Pyrolysis, under the same process conditions. The partial substitution of Mg by Co in MgAl<sub>2</sub>O<sub>4</sub> and the incorporation of Al<sub>2</sub>O<sub>3</sub>, SiO<sub>2</sub>, MgO, H<sub>3</sub>BO<sub>3</sub> in the spinel and SHS synthesis of KVO<sub>3</sub> all increase the catalytic conversion efficiency while at the same time they suppress substantially the formation of coke. It was found that SHS-KVO<sub>3</sub> catalytically accelerates the gasification of coke deposited on the catalyst surface and its optimum values were found to be more than 10 wt.%. The addition of B<sub>2</sub>O<sub>3</sub> into the KVO<sub>3</sub>-based catalyst causes a strong interaction between KVO<sub>3</sub> and SHS support, which decreases the loss by evaporation of the active phase
