초록

본 연구는 펄스 반응기 및 고정층 연속반응기를 사용하여 γ-알루미나에 담지된 니켈촉매상에서 이산화탄소에 의한 프로판의 개질반응 특성을 고찰한 것이다 Ni/γ-A1₂O₃촉매가 NiO/γ-A1₂O₃촉매보다 CO₂의 해리능력과 프로판의 개질 능력이 우수한 것으로 나타났다. 프보판과 CO₂의 혼합물에 산소를 추가한 결과 프로판의 전환율이 증가하였고 표면의 탄소침적도 감소함을 알 수 있었다. Ni/γ-A1₂O₃와 Ga₂O₃의 기계적 혼합 촉매는 Ni/γ-A1₂O₃자체보다 촉매의 활성이 오래 유지되었고 두 상의 협동에 의한 상승효과(synergistic effect)가 관찰되었다.

Reforming of propane by carbon dioxide using NiO/γ-A1₂O₃ was carried out in a pulse or continuous kid bed reactor. NiO/γ-A1₂O₃ showed higher dissociation ability of CO₂ than NiO/γ-A1₂O₃, and the former exhibited higher conversion of propane than the latter. The presence of oxygen in the reaction mixture of propane and CO₂ increased the conversion of propane and reduced the amount of carbon deposit on the catalyst surface. Mechanical mixture catalyst of NiO/γ-A1₂O₃ and Ga₂O₃ showed higher stability to deactivation than NiO/γ-A1₂O₃ itself. The synergistic effect between NiO/γ-A1₂O₃ and Ga₂O₃ was also observed in this study.
