The catalytic pyrolysis of naphtha has been performed in a quartz reactor to produce the light olefins at high yields. The catalytic pyrolysis leads to 10 and 5% higher values in the yields of ethylene and propylene, respectively, compared to the thermal pyrolysis at the same operation condition. The enhancement of olefin yield in the presence of catalyst comes from the better heat transfer through the catalyst particles. KVO3 plays role of a catalyst to accelerate the gasification of coke deposited on the catalyst surface and its optimum range is found to be more than 10 wt.%. An addition of B2O3 into KVO3-based catalyst causes a strong interaction between metal oxide (KVO3) and alpha-Al2O3 support, which decreases the loss by an evaporation of active phase.
