Catalytic pyrolysis of ulva lactuca (UL) macroalgae was studied over a series of ZrO supported metal such as Co, Ni and Co-Ni metal catalysts at temperature range of 300-500 °C. Highest bio-oil yield (47.8 wt%) was found with Co-Ni/ZrO (10 wt%) catalyst while non-catalytic yielded 42.5 wt% bio-oil. Moreover with increases the metal amount to 15 wt%, the bio-oil yield slightly increased (49.2 wt%). The bio-oil quality significantly improved with using the catalysts compared to the non-catalytic pyrolysis. Catalytic pyrolysis also revealed that introducing Co-Ni into the ZrO could result in higher surface area and which increased active sites. Catalytic bio-oils were consisted of mainly long chain hydrocarbon in the range of C-C. Moreover, the catalytic bio-oils were showed the higher 'high heating value' (HHV) 38.1 MJ/kg as compare to non-catalytic bio-oils (29.4 MJ/kg). Catalysts have been showed excellent recyclability on bio-oil yield and compounds selectivity.
研究了一系列 ZrO 负载的金属（如 Co、Ni 和 Co-Ni 金属催化剂）在 300-500°C 的温度范围内对浒苔（UL）大型藻类的催化热解。在 Co-Ni/ZrO（10wt%）催化剂存在下，生物油产率最高（47.8wt%），而无催化剂时生物油产率为 42.5wt%。此外，随着金属量增加到 15wt%，生物油产率略有增加（49.2wt%）。与无催化热解相比，使用催化剂可显著提高生物油的质量。催化热解还表明，将 Co-Ni 引入 ZrO 中可以产生更高的表面积，从而增加活性位点。催化生物油主要由 C-C 范围内的长链碳氢化合物组成。此外，催化生物油的“高热值”（HHV）为 38.1MJ/kg，高于无催化生物油（29.4MJ/kg）。催化剂在生物油产率和化合物选择性方面表现出良好的可回收性。
