Abstract: Use of a particular form of carbon—carbon nanotubes—as the catalyst. The present technology uses CNTs produced via air-assisted chemical vapor deposition (CVD), which can produce these extremely active catalysts (over an order higher in the magnitude of the activity of the catalyst as compared to the conventional Fe based catalyst) in a single step for converting carbonaceous materials such as coal, biomass, natural gas to liquid fuels such as gasoline, diesel, jet fuel, kerosene etc. . . . , which is generally accomplished through three process blocks.

Abstract: A chemical vapor deposition (CVD) method using a vapor phase catalyst of directly growing aligned carbon nanotubes on a metal surfaces. The method allows for fabrication of carbon nanotube containing structures that exhibit a robust carbon nanotube metal junction without a pre-growth application of solid catalytic materials to the metal surface or the use of solder or adhesives in a multi-step fabrication process.

Abstract: Monolithic, macroscopic, nanoporous nanotube filters are fabricated having radially aligned carbon nanotube walls. The freestanding filters have diameters and lengths up to several centimeters. A single-step filtering process was demonstrated in two important settings: the elimination of multiple components of heavy hydrocarbons from petroleum, a crucial step in post-distillation of crude oil, and the elimination of bacterial contaminants such as Escherichia coli or the nanometer-sized poliovirus from drinking water. All the filtration processes were repeated several times with completely reproducible results. These nanotube filters can be cleaned repeatedly after each filtration process to regain their full filtering efficiency.
