Three-Dimensionally Ordered Macro-porous (3DOM) Fe based catalysts were synthesized via a facile “glyoxylate route” poly (methyl methacrylate) (PMMA) colloidal crystal template (CCT) method. Fischer Tropsch Synthesis (FT) using different biosyngasses over the 3DOM Fe based catalyst for producing the liquid hydrocarbon was studied. The morphology, structure and microstructures of 3DOM Fe based catalysts were characterized by SEM, BET, TPR, HRTEM, XRD, XPS and DRIFTS. The experimental results demonstrated that the hydrogen lean syngas decreased the partial pressure of H₂/CO, which caused the decrease of the CO conversion rate during FT reaction. Moreover, the addition of CO₂ and CH₄ in the hydrogen lean syngas could well preserve the iron carbide phase in the catalyst, and the CO conversion rate was improved. Lower H₂/CO ratio syngas would shift the liquid hydrocarbon distribution to higher molecular weight hydrocarbons, and the addition of CO₂ and CH₄ into the syngas further facilitated the shift. Meanwhile, it was also found that the CO conversion rate and C⁵⁺ selectivity were 68.23% and 70.44% respectively during the simulated biosyngas from biomass gasification (the hydrogen lean syngas contained CO₂ and CH₄) FT over the 3DOM Fe based catalyst, and CO₂ and CH₄ selectivity were 12–26% and 2.67–5.5% respectively.

通过一种简便的“乙醛酸途径”聚（甲基丙烯酸甲酯）（PMMA）胶体晶体模板（CCT）方法合成了三维有序大孔（3DOM）铁基催化剂。研究了在3DOM铁基催化剂上使用不同的生物合成物进行费托合成（FT）的方法，该催化剂用于生产液态烃。通过SEM，BET，TPR，HRTEM，XRD，XPS和DRIFTS对3DOM铁基催化剂的形貌，结构和微观结构进行了表征。实验结果表明，贫氢合成气降低了H ₂ / CO的分压，导致FT反应过程中CO转化率降低。此外，添加了CO ₂和CH ₄贫氢合成气中的硫能很好地保留催化剂中的碳化铁相，并提高了CO的转化率。较低的H ₂ / CO比合成气会使液态烃分布转变为较高分子量的烃，向合成气中添加CO ₂和CH ₄进一步促进了这种转变。同时还发现，在3DOM Fe基催化剂上，模拟生物质气化的生物合成气（贫氢合成气含有CO ₂和CH ₄）FT时，CO转化率和C ⁵⁺选择性分别为68.23％和70.44％，和CO ₂和CH ₄ 选择性分别为12–26％和2.67–5.5％。
