| 摘 要： | 在间歇过程的碳纳米管制备实验基础上结合经验公式,开发设计了制备碳纳米管的半连续中试流化床反应器,结果表明:催化剂100 g、反应温度650℃时,甲烷平均转化率23.2%,碳纳米管产率为177.5 g/h,操作周期为间歇反应器的1/3,反应器可较好地实现碳纳米管制备功能。用计算流体力学方法对此反应器内的气固两相流化行为进行数值模拟,得到在工况条件下,最佳的催化剂用量为100 g、操作气速为0.15 m/s等工艺参数。

| Abstract: | Semi-continuous pilot test fluidized bed reactor for carbon nanotubes preparation was designed and fabricated,base on experiments of batch fluidized bed reactor and repeated calculations.When reaction temperature is 650 ℃,reaction time is 4 h,velocity of CH4,H2,N2 are 0.1m/s,0.008 m/s,0.016 m/s,the yield of carbon nanotubes is 177.5 g/h,conversion of CH4 is 23.2%,production cycle is shortened by 2/3.The fluidization behavior of gas-solid fluidization process was calculated by using the computational fluid dynamics(CFD) package Fluent6.1.And the optimal condition for carbon nanotubes is that the velocity of CH4 is 0.1m/s,and catalyst is 100g. |
