Abstract
With the rapid development of the petroleum industry, the oxygen content in petroleum products has attracted increasing attention due to its significant impact on product quality, storage stability, and combustion performance. This study aims to investigate the key scientific issues associated with oxygen removal technologies during the refining of petroleum products and proposes an efficient and environmentally friendly deoxygenation method to meet modern industrial requirements. Based on two primary technological approaches—catalytic hydrogenation and adsorption separation—the study integrates the design and optimization of novel catalysts and adsorbent materials, systematically analyzing the effects of various process conditions on deoxygenation efficiency. Experimental validation reveals that a process scheme combining supported me tal catalysts with porous molecular sieve composite materials can substantially enhance deoxygenation selectivity and reaction rates while reducing energy consumption and by-product formation. The results indicate that under optimized conditions, this technology can reduce the total oxygen content in model oil from its initial value to below 10 ppm, with the catalyst exhibiting excellent stability and reusability. Furthermore, this study presents for the first time a kinetic model based on microscopic reaction mechanisms, providing a theoretical basis for precise control of the deoxygenation process. Overall, this research not only offers innovative solutions for the deep deoxygenation of petroleum products but also lays an important foundation for technological development in related fields, demonstrating significant academic value and application potential..
