Title: Producing vapor grown carbon fibers with high sulfur coal without SO{sub 2} emissions

Abstract

This paper describes the development of a unique process that produces a highly graphitic, vapor grown carbon fiber (VGCF) from the gas phase in pound quantities. Past vapor grown carbon fiber progress has stagnated because the iron catalyst did not grow filaments profusely enough to make a practical continuous reactor. It has been found that adding H{sub 2}S at an equimolar level with the iron catalyst, the filament formation vastly increases. Coal is desirable as a sulfur source, for it eliminates the need for handling toxic H{sub 2}S, and it is a very low cost hydrocarbon supply for the process. We show that Ohio, high-sulfur coal containing 2.5 to 4.6% sulfur accomplishes both tasks. There is also evidence that sulfur from the coal remains with the carbon fiber catalyst during the reaction and does not exhaust as SO{sub 2} into the atmosphere.
