PRODUCTION OF CARBON FIBER

摘要

PURPOSE:To obtain the titled fiber in high efficiency and yield, by mixing a carbon compound gas with catalyst particles and a specific radical generating substance as a reaction initiator and reacting in a hot preheating zone and then in a reaction zone. CONSTITUTION:A raw material gas such as methane, ethane and butadiene is mixed with (A) a reaction initiator consisting of a radical generating substance which is an aromatic compound (derivative) capable of forming benzene radical in the reaction atmosphere (e.g. chlorobenzene) and (B) catalyst particles such as ferrocene. The mixture is introduced into a preheating zone heated at 300-700 deg.C to generate benzene radical from the radical generating substance. The obtained mixture is introduced into a reaction zone heated at 800-1150 deg.C to accelerate the reaction and obtain the objective carbon fiber.
