Abstract
크기 80∼100 mesh의 실리카젤을 유동입자로 사용한 직경 5.08 cm인 열유동층 반응기에서 메탄의 염소화 반응에 관하여 연구하였다. 반응 속도식은 각 물질에 대하여 일차식으로 주어지며 전체반응은 2차비가역반응임이 확인되었다. 관상반응 모델을 사용하여 실험치로부터 반응속도 정수를 구했으며, 일정한 온도에서의 관상반응 모델로부터 구한 생성물 분포와 실험치들을 비교 검토한 결과 잘 일치함을 알았다. 반응온도(330∼420℃), 원료의 몰비 (0.5∼4 Cl2/CH4), 반응시간(5∼30 sec)이 각각 전환율과 생성물 분포에 미치는 영향을 실험적으로 조사했으며, 전환율과 생성물 분포를 고려하여 각 생성물의 최적 반응조건을 제시하였다. 이때 최적반응 온도는 390∼420℃이었다.
Chorination of methane was studied in a 5.08 cm-diameter thermal fluidized bed with silica gel particles in the range of 80∼100 mesh. The data are expressed in the form of second order irreversible rate equation. The rate constant were determined by plug flow model and experimental data, and plug flow model yielded product distribution in a good agreement with experimental results within the range of experimental conditions. The effect of temperature (330∼420 ℃), feed mole ratio (0.5∼4 Cl2/CH4), and reaction time(5∼30 sec) on conversion and product distribution were experimentally investigated to determine the optimum reaction conditions for each chlorinated methane. The optimum reaction temperature was found to be in the range of 390∼420 ℃ for all chlorinated methanes.
