Abstract
이산화황을 환원제로 한 함티탄자철광의 황화반응에 있어서 공업적으로 이용 가능한 환원제의 선택 및 그 사용가능 여부를 조사하고자 무연탄, 목탄, 코크스, 활성탄을 선택하여 C-SO2계의 반응을 조사하고 이의 결과를 함티탄자철광의 황화반응에 적용, 조사하였다.
본 황화반응에서는 무연탄이나 코크스보다는 목탄과 활성탄이 훨씬 좋은 결과를 나타내었다. 목탄을 사용하였을 때의 최적반응온도는 700 ℃였고, 활성탄을 사용하였을 때의 최적반응온도는 750 ℃였다. 이때의 반응조건은 반응시간 : 1시간, 함티탄자철광에 첨가되는 환원제의 무게비 : 0.7, SO2 유량 : 100 cm3/min（반응관크기 : 내경=2.8 cm, 길이=100 cm）였다.

The reactions in C-SO2 system and in titaniferous magnetite-C-SO2 system were examined to select a reducing agent that is practicable for industrialization of the sulfidization process of titaniferous magnetite with sulfur dioxide.
Anthracite, charcoal, coke and activated carbon were used as a reducing agent in this study.
As a result, charcoal and activated carbon were prefered reducing agent to anthracite and coke.
The optimum reaction temperature was 700 ℃ when charcoal was used as a reducing agent and was 750 ℃ when activated carbon was used as a reducing agent under the conditions of reaction time 1 h, weight ratio of added reducing agent to titaniferous magnetite 0.7 and SO2 flow rate 100 cm/min（reactor size : ID=2.8 cm, length=100 cm）.
