摘要
本文对碳纳米管的结构、特性、用途进行了简单回顾 ,并对制备碳纳米管的三种方法 ,激光烧蚀法、电弧放电法 ,催化裂解法作了简要介绍。还对催化裂解法制备CNTs固定床、沸腾床、移动床和浮动催化法等四种工艺进行了对比。目前以天然气为原料气 ,镍系催化剂 ,碳纳米管的生产成本可降至15万元 /吨。
The structure, characteristic, usage of carbon nanometer tube, and three methods of preparing nanometer tubes, including laser ablation, arc discharge and catalytic cracking, are reviewed briefly in this paper. Also the comparisons with four catalytic cracking processes of producing (CNTs),including fixed bed, fluidized bed, moving bed and floating catalysis,are carried out. At present, using natural gas as raw material and catalyst of Ni Group, the production cost of CNTs would be decreased to 150,000 RMB/t.
