Transcripción del resumen del autor. The pyrolysis performance of catalytic cracking naphtha and coker naphtha on different carriers and an active catalyst was investigated in a confined fluidized bed reactor. For the pyrolysis of catalytic cracking naphtha on quartz grain, the yield of total light olefins increased with the enhancement of temperature, while it varied slightly with increasing weight hourly space velocity (WHSV) and steam/oil weight ratio. The optimal reaction temperature, WHSV, and steam/oil weight ratio were 700 °C, 5.7 h-1, and 0.5, respectively. The selectivity of total light olefins of coker naphtha was better than that of catalytic cracking naphtha under the optimal reaction conditions. The surface area and pore size of the inert carrier showed little effect on the pyrolysis performance. The introduction of the active catalyst could improve the conversion and the yield of total light olefins.
