AI Technical Summary
The existing hydrogen deoxygenation catalysts have problems such as scarcity of precious metal resources, expensive prices, high industrial application costs and poor long-term catalytic stability. At the same time, the low-temperature catalytic activity and catalytic efficiency of non-precious metal catalysts are poor, poor selectivity, prone to side reactions, and poor stability.
Co-precipitation under the action of oxalic acid by using copper chloride, manganese sulfate, and lanthanum chloride to co-precipitate under the action of oxalic acid. After calcination, the spinel structure active support was obtained, and Cu-MOF was combined with the active support through in-situ composite treatment to prepare a deoxygenation catalyst.
The low-temperature catalytic activity and catalytic efficiency of non-precious metal deoxygenation catalysts are improved, the catalytic temperature is reduced, the selectivity of hydrogen deoxygenation is improved, the occurrence of side reactions is avoided, and the stability and long-term service life of the catalyst are significantly improved.
