Abstract A process for preparing light olefin by catalytic cracking of low-carbon paraffin containing C4-C6 paraffin includes dehydrogenating pretreating of said low-carbon paraffin by contacting it with dehydrogenating catalyst in catalytic dehydrogenation reactor, delivering to dehydrogenated resultant and raw oil to the nozzle at lower part of catalytic caracking lift pipe, atomizing with steam, spraying it in said lift pipe, and catalytic cracking under existance of catalytic cracking catalyst whose main component is Y-zeolite. Its advantages include high transform rate, and high selectivity of ethylene and propylene.
