황화 CoMo/Υ-Al2O3 촉매상에서 탈활반응과 탈산소반응의 상호작용
Interactions between Hydrodesulfurization and Hydrodeoxygenation over Sulfided CoMo/Υ-Al2O3 Catalyst
박해경, 전광승, 김경림
황화 CoMo/Υ-Al2O3 촉매를 사용하여 423-723K의 온도와 10×105-50×105Pa 압력 그리고 접촉시간 0.0125-0.03g-cat. hr/ml-feed 범위에서 thiophene 의 수첨탈활반응과 m-cresol에 의해 수첨탈산소반응의 상호작용 및 그 속도론에 관하여 연구하였다. 연구결과 thiophene의 수첨탈황반응은 모두 온도, 압력범위에서 m-cresol에 의해 억제되었으며, 억제 효과는 저온에서 더 현저했다. Thiophene의 수첨탈황반응속도식 및 m-cresol의 수첨탈산소반응속도식을 LHHW모델을 이용하여 구한 결과 ΥHDOㆍKcㆍCc/(1+KcㆍCc+KrㆍCr), ΥHDS=kHDSㆍKtㆍCt/(1+KcㆍCc+KtㆍCt)이었다. 각 온도에서 반응속도상수 및 흡착평형상수를 구하였으며 Arrhenius plot을 행하여 구한 활성화에너지 값은 m-cresol과 thiophene이 각각 17.79kcal/mole, 13.51kcal/mole이었다.
Interactions between thiophene hydrodesulfurization(HDS) and m-cresol hydrodeoxygenation (HDO) and the kinetic analysis were studied over sulfided CoMo/γ-Al2O3 catalyst at the range of temperatures between 423K and 723K, the total pressures between 10×105Pa and 50×105Pa and the contact times between 0.0125g-cat. hr/ml-feed and 0.03g-cat. hr/ml-feed. Hydrodesulfurization of thiophene was inhibited by the presence of m-cresol at all temperatures and pressures and hy-drodeoxygenation of m-cresol was also inhibited by the presence of m-cresol at all temperatures and pressures but inhi-bition effect was severer at low temperatures. The rate equations of thiophene and m-cresol was given to be HDS=kHDSㆍKTㆍCT/(1+KCㆍCC+KTㆍCT)andγHDO=kHDOㆍKCㆍKC/(1+KCㆍCC+KTㆍCT) in terms of Langmuir -Hinshelwood-Hougen-Watson model. At each temperature, reaction rate constants and adsorption equilibrium constants were determined and the activation energies of thiophene HDS andm-cresol HDO were 13.51kcal/mole and 17.79kcal/mole, respectively.
