Abstract: A filtration system that uses a filter to convert wastes in automotive exhausts into carbon nanotubes is disclosed. Metallic salts, such as iron salts, may be mixed with diesel fuel by way of using algal biodiesel to ensure homogenous suspension of the metallic salts in the diesel fuel. The metallic salts form a suitable catalyst to grow carbon nanotubes on a filter placed in the pathway of the diesel combustion exhaust. The filter surface may be composed of iron of similar catalyst. The filter may be placed along the pathway of exhaust streamlines preferably at an angle of more than 5 degrees and less than 15 degrees. The filter is heated to temperatures in the range of 200-1000 degrees Celsius. The filter described in this invention can work in its own or supplement existing filtration systems. The filtration system may produce a material that is commercially valuable, synthesized carbon nanotubes.

Abstract: We disclose a novel filter and process that converts the wastes in automotive exhausts into carbon nanotubes. The filter surface is composed of iron of similar catalyst. The filter is placed along the pathway of exhaust streamlines preferably at an angle of more than 5°. and less than 15°. The filter is heated to temperatures in the range of 200-1000° C. The filter described in this invention can work in its own or supplement existing filtration systems. The end product of this filtration system is a material that is commercially valuable. The synthesized carbon nanotubes are purified using ionic liquid solution that is capable of removing undesirable carbonated material and leaving 95% purified carbon nanotubes. The purified carbon nanotubes have a diameter of 20-50 nm and a length of 1-10 micro meters.
