Abstract

The chlorination of the titanium slag from titaniferrous magnetite by the arc-smelting in a fluidized bed reactor was investigated to produce $TiCl_4$ from domestic titaniferrous magnetite. The optimum conditions are as follows : reaction temperature; $950^{\circ}C$, reaction time; 90min, $Cl_2$ gas velocity; 3cm/sec, and petroleum coke-to-titanium slag weight ratio; 0.18. Also the mean diameter of titanium slag and petroleum coke was $44.6{\mu}m$ and $67.9{\mu}m$ respectively. Under these conditions 97.07% of Ti component in the titanium slag was chlorinated and the purity of $TiCl_4$ from this chlorination was 96.2%.

국내 부존 함티탄자철광으로부터 염화티타늄($TiCl_4$)을 제조키 위해 함티탄자철광의 arc-smelting으로부터 얻어지는 titanium slag의 유동층 염소화 반응을 조사하였다. Titanium slag의 유동층 염소화반응에 적절한 반응조건은 반응 온도 $950^{\circ}C$, 반응시간 90분, 염소가스의 유속 3.0cm/sec, titanium slag에 대한 petroleum coke의 무게비 0.18, 그리고 titanium slag 및 petroleum coke의 입자의 평균직경은 각각 $44.6{\mu}m$, $67.9{\mu}m$였다. 위 조건하에서 titanium slug 중의 97.07%의 티타늄이 염소화 되었으며 제조된 염화티타늄($TiCl_4$)의 순도는 96.2%였다.
