在USC裂解炉上进行了不同乙烯原料、裂解炉出口温度、炉管构型的工业裂解标定试验，结果表明，循环乙烷易脱氢生成大量的乙烯（56.35%），丙烯、丁二烯、裂解液相产物收率极低，液化气通过断链反应可生成乙烯、丙烯、丁二烯以及少量的裂解液相产物，石脑油&拔头油裂解乙烯收率低，但裂解液相产物（高附加值）收率较高；乙烷裂解炉出口温度宜控制在858℃左右；与U型炉管相比，乙烷在M型炉管裂解乙烷转化率、乙烯收率、丙烯收率、三烯收率高。

A series of industrial pyrolysis calibration tests with different raw materials for ethylene, outlet temperatures and furnace tube configurations are carried out in a USC cracker.It is found that circulated ethane is easily dehydrogenated to produce a large amount of ethylene (56.35%), while the yields of propylene, butadiene and pyrolysis liquid phase are very low.Liquefied petroleum gas can generate ethylene, propylene, butadiene and a small amount of pyrolysis liquid phase products through the chain scission reaction.The pyrolysis of naphtha mixed with Topped oil can give a low yield of ethylene through but a high yield of high-valuable liquid phase.The outlet temperature at ethane cracker is suggested to be controlled at around 858℃.Comparing with pyrolysis in a U-shape furnace tube, ethane pyrolysis in a M-shape furnace tube can obtain higher ethane conversion rate, ethylene yield, propylene yield and the total yield of ethylene, propylene and butadiene.
