Abstract A series of NiO–MoO3 promoted Pt/ZrO2–TiO2–Al2O3 catalysts were investigated in the cracking reactions of n-decane under supercritical conditions. The results show that the addition of NiO could facilitate the formation of strong acid sites, which are contributed to improving the cracking performance. The catalyst with 6.0 wt.% NiO shows the highest catalytic cracking activity among all catalysts, with the gas yield increased by 18.3% at 650 °C and the heat sink correspondingly increased by 0.61 MJ/kg compared to thermal cracking.

NiO-MoO3 促进 Pt/ZrO2-TiO2-Al2O3 催化剂具有优异的正癸烷裂解性能

摘要 研究了一系列 NiO-MoO3 促进的 Pt/ZrO2-TiO2-Al2O3 催化剂在超临界条件下正癸烷的裂化反应中。结果表明，NiO的加入可以促进强酸位点的形成，这有助于提高裂解性能。含 6.0 wt.% NiO 的催化剂在所有催化剂中表现出最高的催化裂化活性，与热裂化相比，在 650 °C 下气体产率提高了 18.3%，热沉相应增加了 0.61 MJ/kg。
