CoMoCat

Thin walled carbon nanotubes have shown promise as a means of desulfurization. (See, for example, the article cited at the end of this blog entry.) The high cost of manufacturing such nanotubes, however, has made the economics of this type of desulfurization prohibitive.

That’s why the work of Carbon Nanotubes Research @ Oklahoma State University is so fascinating. According to their Web site …

“At the University of Oklahoma we pointed out that the catalytic decomposition method was suitable for scaling up and for achieving a "controlled production" of SWNT. By this we implied the ability to control the selectivity towards SWNT by changing catalyst parameters and operating conditions, all combined with the ability to obtain a reliable quantitative measurement of the amount of SWNT produced.

“For the last 8 years we have been performing research on the development and optimization of a cost effective method that we named CoMoCat process. Our expertise in heterogeneous catalysis allowed us to tailor the material in such a way that selectivity and yield are maximized. The method employed involves disproportionation of CO at moderate pressure and temperature, which results in a scalable, cost-effective process.”
