초록

탄소 nanotube, nanofiber 및 powder를 사용하여 아세틸렌 흡착실험을 수행한 결과 탄소 nanotube가 최적의 흡착성분을 보였다. 이를 지지체로 하여 Pd 농도 0~5%, 흡착온도 30~80 ℃ 및 C2H2/CO2의 비 3~10의 범위에서 3-요인, 3-수준의 Box-Behnken Design(BBD)으로 15개의 실험 조건을 설계했다. 이를 바탕으로 2차 다항식 회귀분석으로 운전조건에 따른 흡착량 예측식을 도출하였다. ANOVA 분석의 F-value 측정에 따라 흡착온도가 가장 큰 영향지수를 보였고 C2H2/CO2의 비는 가장 작은 영향지수 보이는 것으로 나타났다. 하지만 주요인자 간의 교호작용은 거의 없는 것으로 분석되었다. 흡착량 최적화 분석에서 Pd 농도 3.0%, 흡착온도 47 ℃ 및 C2H2/CO2 = 10인 조건에서 22.0 mmol/g이 흡착되는 것으로 계산되었고 실제 실험치에 95.9%의 정확도를 보였다.

Carbon nanotubes, nanofibers and powders were used for acetylene adsorption experiments. A total of 15 different experiments were designed by 3-level of Box-Behnken Design (BBD) with 3 factors including the Pd concentration of 0 to 5%, adsorption temperature of 30 to 80 ℃ and C2H2/CO2 of 3 to 10. Based on those data, a second order polynomial regression analysis was used to derive the adsorption amount prediction equation according to operating conditions. The adsorption temperature showed the greatest influence index while the C2H2/CO2 ratio showed the smallest according to the F-value measurement of the ANOVA analysis. However, there was little interaction between major factors. In the adsorption optimization analysis, a 22.0 mmol/g was adsorbed under the conditions of Pd concentration of 3.0%, adsorption temperature of 47 ℃ and C2H2/CO2 of 10 with 95.9% accuracy.
