In recent years, due to soaring oil prices and the excessive development of energy, more and more attention is paid to using other resources to replace oil [, coal chemical industry in this situation developed rapidly, coal oil, coal-olefin project has been commercialized Operation, business efficiency is necessary to continuously improve the input-output ratio. C2H4, C3H6, H2 and other step-up metering into the reaction unit, the catalyst is also sent by pressure and measurement.
In the project of coal-to-olefins, ethylene and propylene react to polyethylene and polypropylene in the reaction of catalyst, and the reaction of ethylene, propylene and H2 can be poisoned by CO and CO2 in raw materials. So the detection of trace CO and CO2 has important significance. The determination process and influencing factors were discussed, and the optimized experimental parameters were obtained. The experimental results show that the CH4 reformer temperature is set at 360 ℃ and the carrier gas flow rate is set at 30.0 mL / min.
近年来,由于石油价格的飙升以及能源的过度开发,人们越来越重视用其它资源来代替石油[,煤化工就在这种形势下迅猛发展起来,煤制油、煤制烯烃项目已经商业化运行,企业以效益为目的就要不断地提高投入产出比。C2H4、C3H6、H2等升压计量送入反应单元,催化剂也经压送和计量。
煤制烯烃项目中,乙烯、丙烯在催化剂作用下反应生成聚乙烯、聚丙烯,其中作为原料的乙烯、丙烯、H2中的微量CO和CO2会使催化剂中毒,影响其反应。故检测其中的微量CO和CO2有重要的意义。对测定过程和影响因素进行了探讨,得出了***优化的实验参数。实验显示CH4转化炉温度设置为360℃,载气流速设置为30.0 mL/min***佳。
