Problems solved by technology

Natural gas reserves have been found in remote areas where it is uneconomical to develop the reserves due to the lack of local markets for the gas and the high cost of transporting the gas to distant markets.
This high cost is often related to the extremely low temperatures needed to liquefy the highly volatile gas during transport.
However, the current number of applications of conventional carbon filaments is limited.

[0042] The invention having been generally described, the following example is given as particular embodiments of the invention and to demonstrate the practice and advantages thereof. It is understood that the examples are given by way of illustration and are not intended to limit the specification or the claims to follow in any manner.

[0043] Carbon filaments were prepared using a tube furnace with a quartz reactor tube containing a Monel screen (1″W×6″L). First, the tube furnace was heated to 650° C. under N2 flow at 200 mL / min. Once the temperature reached 650° C., ethylene flowing at 200 mL / min and N2 flowing at 60 mL / min were fed to the furnace, and the exit gases were analyzed using a gas chromatograph (GC) containing a thermal conductivity detector (TCD) for hydrocarbon products. The reaction was continued at 650° C. for a time period ranging from 1 hour to 4 hours, with 2 hours being the standard run length. After this time, the gas flows were stopped, and the reactor was al...

Abstract

Metal loaded carbon filaments and a process for making the same are provided. This process includes forming metal on carbon filaments produced from at least one carbon-containing compound, e.g., an alkane or an alkene. The metal may be formed on surfaces of previously formed carbon filaments by, for example, electroplating, impregnation, or chemical vapor deposition. Alternatively, the carbon filaments and the metal may be formed concurrently, resulting in the metal being incorporated in the carbon filaments. An article of manufacture is also provided that includes a carbon filament having metal disposed thereon. The article of manufacture may be, for example, a high surface area catalyst, an electronic element, and a composite material having enhanced electrical properties.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. REFERENCE TO A MICROFICHE APPENDIX [0003] Not applicable. FIELD OF THE INVENTION [0004] This invention generally relates to the production of carbon filaments. More specifically, the invention relates to metal loaded carbon filaments and a process for making the same. BACKGROUND OF THE INVENTION [0005] Natural gas reserves have been found in remote areas where it is uneconomical to develop the reserves due to the lack of local markets for the gas and the high cost of transporting the gas to distant markets. This high cost is often related to the extremely low temperatures needed to liquefy the highly volatile gas during transport. An alternative is to locally convert the natural gas to products that can be transported more cost effectively. [0006] Natural gas comprises several components, including alkanes, i.e., saturated hydrocarbons...
