The reaction performance of catalytic cracking of crude oil to produce low carbon olefins was investigated in a small fixed fluidised bed reactor.The suitable operating conditions for the production of low-carbon olefins by catalytic cracking of crude oil were explored by varying the reaction temperature and water-to-oil ratio,and the cracking performance of different fractions was investigated.The results showed that at a reaction temperature of 750 ℃ and a water-to-oil ratio of 0.5,the one-way yield of ethylene could reach 18.84％,the one-way yield of propylene could reach 11.83％,the one-way yield of butene could reach 4.53％,and the ethylene+propylene+butene yield could reach 35.2％with an intermediate-paraffinic-based crude as the feedstock.
