유동층 반응기에서 함티탄자철광의 선택염소화 반응
Selective Chlorination of Iron from Titaniferrous Magnetite in a Fluidized Bed Reactor
초록
유동층 반응기에서 함티탄자철광의 염소화 반응에 의해 함티탄자철광중의 철분만을 선택적으로 분리할 수 있는 염소화 조건과 아울러 rutile 대용품의 제조 가능성을 조사하였다. 염소화 반응의 적정조건은 반응온도 950℃, 반응시간 2시간, 함티탄자철광에 대한 환원제 petroleum coke의 무게비 0.12 그리고 염소가스의 유속은 5cm/sec이었다. 이 반응조건하에서 얻어진 반응잔사는 TiO2 함량 70%이며 X-선 회전분석 결과 rutile로 확인되는 rutile 대용품이었다.
A selective chlorination of titaniferrous magnetite in a fluidized bed reactor was investigated to find the optimum condition for selective removal of Fe component from low grade titaniferrours magnetite ore and to produce a rutile substitute from titaniferrous magnetite ore. The optimum chlorination condition was determined to be a temperaure of 950℃, 2hr of reaction time, reducting agent(petroleum coke) to titaniferrous magnetite weight ratio of 0.12, and Cl2 gas velocity of 5cm/sec. Under the above mentioned condition, 99% of Fe in titaniferrous magnetite was removed and the reaction residue which became rutile substitute was identified as rutile by x-ray diffraction and was found to contain 70% TiO2.
