Abstract:

Green carbon science has become the scientific foundation for carbon neutrality. The evolution of C－C and C－H bonds during the hydrocarbon conversion process runs throughout the entire carbon cycle. In the evolution of C－C bonds, there must simultaneously be the breaking and formation of C－H bonds, meaning that hydrogen transfer reactions also occur. This paper focuses on hydrogen transfer reactions in the hydrocarbon conversion process, reviewing from three dimensions: mechanisms of hydrogen transfer reactions, regulation of hydrogen transfer reactions, and application of hydrogen transfer reactions in product-oriented hydrocarbon conversion processes. From the perspective of hydrogen transfer reactions, it envisions the reasonable roles of different carbon resources (fossil resources, biomass resources, waste plastic resources, and CO2 resources) in their efficient conversion as hydrogen acceptors or hydrogen donors. Biomass and water, as potential sustainable hydrogen donors, will play a core role in the construction of future energy systems guided by green carbon science.
