Bimetallic Co-Ru on different mesoporous composite oxides (m-SiO₂-Al₂O₃, m-SiO₂-TiO₂, m-TiO₂-Al₂O₃) and CoRu-m-SiO₂-TiO₂ were synthesized by incipient wet-impregnation (IWI) and one-pot (OP) hydrothermal methods, respectively. Bimetallic catalysts were coated in the microchannels of 3D-printed stainless steel (SS) microreactors for Fischer-Tropsch (FT) studies. The physiochemical properties of the catalysts were examined by BET, XRD, SEM, TEM, TPR, TGA-DSC and XPS techniques. The TPR results showed that the method and the composite support had a profound effect on the reducibility of the active sites. All the catalysts resisted deactivation for first 50 h and 10Co5Ru/m-SiO₂-TiO₂ (IWI) was most stable with ∼80 % CO conversion at the end of 60 h. The stability and activity of the catalysts were observed in the order: 10Co5Ru/m-SiO₂-TiO₂ (IWI) >10Co5Ru/m-SiO₂-Al₂O₃ (IWI) >10Co5Ru/m-Al₂O₃-TiO₂ (IWI) >10Co5Ru-m-SiO₂-TiO₂ (OP). The TPO and XRD analyses of the spent catalysts confirmed coking as a potential factor but not the only cause of catalyst deactivation over time.

不同介孔复合氧化物（m-SiO ₂ -Al ₂ O ₃，m-SiO ₂ -TiO ₂，m-TiO ₂ -Al ₂ O ₃）和CoRu-m-SiO ₂ -TiO ₂上的双金属Co-Ru分别通过初始湿法浸渍（IWI）和一锅法（OP）水热法合成。将双金属催化剂涂覆在3D打印的不锈钢（SS）微反应器的微通道中，以进行费托（FT）研究。通过BET，XRD，SEM，TEM，TPR，TGA-DSC和XPS技术检查了催化剂的理化性质。TPR结果表明，该方法和复合载体对活性位点的还原性具有深远的影响。在开始的50小时内，所有催化剂均抗失活，并且10Co5Ru / m-SiO ₂ -TiO ₂（IWI）最稳定，在60小时后的CO转化率约为80％。按以下顺序观察催化剂的稳定性和活性：10Co5Ru / m-SiO ₂ -TiO ₂（IWI）＞ 10Co5Ru / m-SiO ₂ -Al ₂ O ₃（IWI）＞ 10Co5Ru / m-Al ₂ O ₃ -TiO ₂（IWI）＞ 10Co5Ru-m-SiO ₂ -TiO ₂（OP）。对废催化剂的TPO和XRD分析证实了结焦是一个潜在因素，但并不是随时间推移催化剂失活的唯一原因。
