Traditional hydrocarbon nitridation and oxidation technologies,such as caprolactam(CPL)and propene oxide production technologies,present low atom utilization and serious environmental pollution problems.An urgent need exists for green hydrocarbon oxidation and nitridation technologies.As a well-known green oxidant,hydrogen peroxide(H2O2)is widely used in green hydrocarbon oxidation and nitridation,with water as the only byproduct.However,the low capacity of one single fixed-bed unit of anthraquinone hydrogenation for H2O2 production-which is widely adopted in China-has severely restricted the supply of H2O2,further hampering the development of the green chemical industry in China.The authors'company endeavors to develop slurry bed technology of H2O2 production to promote production capacity,reduce production costs and environmental pollution.Furthermore,green production technologies of CPL and propene oxide with H2O2 have also been developed.The nitrogen atom utilization was enhanced from 60% to nearly 100%,and the carbon atom utilization was also promoted from 80% to nearly 100%.
