Effect of Cu MOF based functional catalysts on cracking and adsorption of bio-oil compounds via thermo-catalytic pyrolysis: A net zero emission scenario

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, pi-pi 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.
