Title: Utilization of high sulfur coal in carbon fiber production. Final report, April 1993--August 1994

Abstract

PYROGRAF-III{trademark} is a highly graphitic vapor grown carbon fiber (VGCF) produced by the chemical vapor deposition of carbon on metallic catalysts in the temperature range of 1000{degrees}C. This is entirely different from commercial carbon fiber, which is made by first forming a filament and then graphitizing it in a high temperature oven. For PYROGRAF-III{trademark} small amounts of sulfur in the form of hydrogen sulfide are added to the process to enhance the yield. This method of supplying the necessary sulfur is both expensive and hazardous since hydrogen sulfide is flammable, toxic, and corrosive. To supply the sulfur more economically and safely, high sulfur coal was proposed as a replacement for the hydrogen sulfide gas. Applied Sciences, Inc. is the sole producer of this material in pound quantities. The primary objective of research grant OCDO-922-8 was to demonstrate that Ohio`s high sulfur coal can replace the expensive, toxic hydrogen sulfide in the production of vapor grown carbon fiber as well as become a partial or complete source of carbon. The secondary objective was to analyze the exhaust for the release of harmful sulfur compounds and to project the economic potential of the use of coal.
