A continuous high-temperature purification reactor for graphite using Freon-12
摘要
Abstract
A new continuous high-temperature reactor for graphite purification using Freon-12 up to 2 600 ℃ was designed with a collection and disposal device for the exhaust such as off-gases, tar and dust. The reactor had an automatic graphite delivery system and amulti-zone temperature control system for feed-in, heating, reaction, cooling and feed-out regions that were controlled within ± 5 ℃. The configuration of heat-insulating materials use da labyrinthine connection for irregularly-positioned multi-layer insulating pieces to isolate air and to prevent heat dissipation. Using this reactor the purity of the graphite can be increased from 88. 2 to 99. 5% with a production capacity of 90 kg/h.关键词
