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

Abstract

The development of a unique process for producing highly graphitic vapor-grown carbon fibers (VGCF) from natural gas in pound quantities has been demonstrated. Prior methods of vapor-grown carbon fiber production using iron particles as the catalyst do not produce fibers profusely enough to make a continuous reactor practical. It has been found that the addition of hydrogen sulfide to the process at an equimolar level with the iron catalyst vastly increases fiber yield. However, since hydrogen sulfide is expensive, toxic and corrosive, coal fines transported into the reactor by a natural gas stream were used as an alternative sulfur source. This paper shows that coal fines pulverized to -325 mesh are a viable source of sulfur for VGCF production. Furthermore, there is evidence that the sulfur from the coal remains with the carbon fiber catalyst during the reaction and does not exhaust as SO{sub 2} into the atmosphere.
