아스팔텐 탈황반응에서 촉매구조의 영향
Effects of Catalyst Structure on Asphaltene Hydrodesulfurization
수소첨가에 의한 아스팔텐 탈황반응에서 촉매구조가 미치는 영향을 검토하였다. 간단한 모델을 설정하여 촉매의 중요한 물리적 특성을 변수로 유효확산계수와 표면적을 계산하였으며 이를 기초로 실험에서 구한 탈황율 경향을 분석하였다. 실험에서 관찰된 반응최고점의 존재는 유효확산계수와 표면적간의 교환효과로 해석될 수 있었다.
The effects of catalyst pore structure on the catalyst activity observed in the catalytic hydrodesulfurization reactions of asphaltenes were studied. In the simplified model, effective diffusivity and surface area were calculated using important physical properties of catalyst and the experimental hydrodesulfurization activity was analyzed based on this calculation. The existence of a maximal point in catalyst activity observed in the reaction could be explained in terms of the trade-off between the effective diffusivity and surface area.
