摘　　要：在毫秒炉装置上以库西石脑油为裂解原料进行了单炉工业标定试验,结果表明:裂解温度控制在840℃,水油比控制在0.63较为适宜;因投油量的改变而导致停留时间变化时,裂解温度也要作相应调整,即当停留时间延长时适当降低裂解温度,反之亦然。由于各裂解炉工况有所差异,操作参数应根据实际生产情况在一定范围内略加调整,而操作参数的选择应首先以保证一个合理的清焦周期为前提,然后再追求目的产物的高收率。The single furnace industrial demarcating was tested with naphtha as cracking material in millisecond furnace.The results showed that the appropriate cracking temperature was 840 ℃and water/oil ratio was 0.63.The cracking temperature should decreased to a suitable degree as the residence time prolonged.
