유동층 부분의 내경 15 ㎝, 높이 183 ㎝, 자유공간（freeboard） 부분의 내경 90 ㎝, 높이 82 ㎝인 유동층 반응기를 이용하여 석유코우크스(petroleum coke) 존재하에 금홍석과 염소의 반응실험을 수행하였다. 실험조건은 반응온도 750-1,000 ℃, 반응압력 1기압, 염소 몰분율 0-0.8, 유동층의 금홍석 조성 10-90 wt%, 고정층(static bed height) 높이 25-45 ㎝이며 사용된 금홍석과 코우크스의 평균입경은 각각 0.1, 0.5 ㎜이다. 반응온도, 염소 몰분율, 유동층 높이 및 유동층의 금홍석 조성이 염소의 반응률과 반응 생성가스 중의 CO/CO₂ 비율에 미치는 영향을 정량적으로 관찰하였으며 본 실험의 결과를 지금까지 발표된 타 연구결과들과 비교 분석하였다.

Experiments on the reaction between rutile and chlorine in the presence of petroleum coke were carried out in a fluidized bed reactor. Inside diameter of the reactor is 15cm in the bed zone and is expanded to 90 cm in the freeboard zone, while the height is 183 cm in the bed zone and 82 cm in the freeboard zone. The ranges of experimental conditions used are as follows : reaction temperature is 750-1,000 ^oC, reaction pressure is held constant at 1 atm, the chlorine mole fraction is 0-0.8, the rutile composition in the bed is 10-90 wt%, and the static bed height is 25-45 ㎝. Average particle diameters of rutile and coke are 0.1 and 0.5 ㎜, respectively. The effects of the reaction temperature, the chlorine mode fraction, the static bed height and the rutile composition in the bed on the chlorine conversion and on the CO/CO₂ ratio in the product gas are investigated quantitatively. The experimental results were also compared with those of other investigators.
