The results of the project in the first two stages showed that the achievement of the task of developing a nanocarbon catalyst that does not contain precious metals for selective hydrogenation of acetylene impurities in ethylene can be achieved by using reduced graphene oxide and composites containing reduced graphene oxide as catalyst. By reducing graphene oxide with hydrazine, a series of nitrogen-doped RGOs were obtained, which showed greater activity and selectivity in the acetylene hydrogenation reaction compared to carbon nanotubes and nitrogen-free RGO. During the previous steps, it was shown that the products of the conversion of acetylene to RGO in a hydrogen atmosphere are ethylene, ethane, and methane. It is shown that changes in such parameters as interlayer distance, crystallite size, surface area, and molar ratios C/O and C/N significantly affect the activity and selectivity of RGO. RGO with high catalytic activity in the acetylene hydrogenation reaction and high ethylene selectivity was developed. It is shown that the hydrogenation of the ethylene-acetylene mixture achieves high selectivity for ethylene in combination with a high conversion of acetylene. The obtained result demonstrates the prospect of the introduction of RGO-based materials in the process of ethylene production at the stage of purification of ethylene from acetylene impurities by selective hydrogenation of acetylene to ethylene.
