This Small Business Innovation Research (SBIR) Phase II project is designed to achieve a pilot-plant demonstration of the technical and commercial feasibility of cost- and energy-efficient large-scale conversion of natural gas to single-walled carbon nanotubes (SWCNT). The research will include: (1) exothermic and selective synthesis of SWCNT by premixed combustion of natural gas after introduction of catalyst precursors with the cold gas mixture; (2) continuous collection of material by means of a bag-house filter; and, (3) detailed understanding of the correlations between operating conditions (pressure, type of catalyst, fuel-oxygen ratio, dilution with inert gas, cold gas velocity) and characteristics of the carbon nanotubes (single-, double-, or multi-walled, diameter, length, conductivity). Results of this project are expected to have a significant impact on the development of the US nanotechnology sector and to strengthen its international competitiveness. Projected sales price of not more than $50/g will lead to a pronounced increase of the number of economically viable SWCNT applications.

这个小企业创新研究（SBIR）第二阶段项目旨在实现将天然气大规模转化为单壁碳纳米管（SWCNT）的技术和商业可行性的试点工厂示范。该研究将包括：(1)在冷气混合物中引入前驱体催化剂后，通过天然气预混燃烧进行放热选择性合成swcnts；(2)利用袋式过滤器连续收集物料；(3)详细了解操作条件（压力、催化剂类型、燃料氧比、惰性气体稀释、冷气速度）与碳纳米管特性（单壁、双壁或多壁、直径、长度、电导率）之间的相关性。预计该项目的结果将对美国纳米技术部门的发展产生重大影响，并加强其国际竞争力。预计销售价格不超过50美元/克将导致经济上可行的swcnts应用数量的显著增加。
