Abstract

Metal organic frameworks based functional catalysts could be utilized to crack and adsorb the bio-oil compounds for green fuel production. This comprehensive investigation examines the effect of three different Cu MOF functional catalysts (Cu MOF, Cu MOF-rGO and Cu MOF-CSC) on cracking and adsorption of hydrocarbon and oxygen-containing compounds in Bombax Ceiba Oil (BC Oil) via the thermo-catalytic pyrolysis process. Attrition based low temperature/pressure induced instruments like a high-speed mixer (HSM) and a four-ball wear tester (FBW) are used to carry out the cracking and adsorption reactions. The Cu MOF-CSC functional catalyst exhibits excellent catalytic cracking and adsorption performance in BC oil due to its high active surface area (59.419 m²/g) and suitable chemical elements (C-40.39 %, O-33.95 %, and Cu-25.66 %). The FBW process-based pyrolyzed BC Oil exhibits improved adsorption of hydrocarbon (9.3 %), oxygen-incorporated compounds (34.24 % of oxygen-bonded hydrocarbon, 3.29 % of chloroacetic acid, undecyl ester (C₁₄H₂₇ClO₂), and 0.90 % of sulphur (2,3-Diphenylcyclopropyl) methyl phenyl sulfoxide, trans-/C₂₂H₂₀OS), and enhanced alkane compounds (14.11 %) via adsorption mechanisms of Lewis acid–base interactions, hydrophobic interactions, π–π stacking interactions, electrostatic interactions, and hydrogen bonding. Overall, the newly synthesized Cu MOF-CSC catalyst might be utilized to produce green fuel in the framework of a net zero emission (NZE) scenario.

基于 Cu MOF 的功能催化剂对热催化热解生物油化合物裂解和吸附的影响：净零排放方案

基于金属有机框架的功能催化剂可用于裂解和吸附生物油化合物，以生产绿色燃料。这项综合研究探讨了三种不同的 Cu MOF 功能催化剂（Cu MOF、Cu MOF-rGO 和 Cu MOF-CSC）对通过热催化热解过程裂解和吸附 Bombax Ceiba Oil（BC Oil）中的碳氢化合物和含氧化合物的影响。在进行裂解和吸附反应时，使用了高速混合器（HSM）和四球磨损测试仪（FBW）等基于低温/压力诱导的磨损仪器。由于 Cu MOF-CSC 功能催化剂具有较高的活性表面积（59.419 m2/g）和合适的化学元素（C-40.39 %、O-33.95 % 和 Cu-25.66 %），因此在 BC 油中表现出优异的催化裂解和吸附性能。基于 FBW 工艺的热解 BC 油对碳氢化合物（9.3 %）、氧结合化合物（34.24 % 的氧结合碳氢化合物、3.29 % 的氯乙酸、十一烷基酯（C14H27ClO2）和 0.90%的硫（2,3-二苯基环丙基）甲基苯基亚砜，反式-/C22H20OS），以及通过路易斯酸碱相互作用、疏水相互作用、π-π堆积相互作用、静电作用和氢键等吸附机制增强的烷烃化合物（14.11%）。总之，新合成的 Cu MOF-CSC 催化剂可用于在净零排放（NZE）框架内生产绿色燃料。
