Catalysis of semihydrogenation of acetylene to ethylene: current trends, challenges, and outlook

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 7, Pages 1031-1059 doi: 10.1007/s11705-021-2113-3

Abstract: Ethylene is an important feedstock for various industrial processes, particularly in the polymer industryUnfortunately, during naphtha cracking to produce ethylene, there are instances of acetylene presenceAn increase in the reaction temperature affords high acetylene conversion and ethylene selectivity toobtain reactant streams free of ethylene.Conflicting findings to this trend have reported the presence of ethylene in the feed stream.

Thermodynamic analysis of ethanol synthesis from hydration of ethylene coupled with a sequential reaction

Jie Gao, Zhikai Li, Mei Dong, Weibin Fan, Jianguo Wang

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 5, Pages 847-856 doi: 10.1007/s11705-019-1848-6

Abstract: Coal-based ethanol production by hydration of ethylene is limited by the low equilibrium ethylene conversionTo improve ethylene conversion, coupling hydration of ethylene with a potential ethanol consumption reactionThe results show that dehydrogenation of ethanol to acetaldehyde has little effect on ethylene conversion, whereas for dehydrogenation of ethanol to acetaldehyde and ethyl acetate, ethylene conversion can beThe esterification of acetic acid with ethanol can greatly enhance the ethylene conversion to 22.5%;

Determination of the diffusion of poly(ethylene glycol) in polypropylene using ATR-FTIR

Hanjia CHEN, Xuhua SHI, Yafei ZHU, Yi ZHANG, Jiarui XU,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 3, Pages 336-341 doi: 10.1007/s11705-009-0230-5

Abstract: The diffusion of poly(ethy1ene glycol) (PEG) in polypropylene (PP) was investigated using attenuated total reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), Atomic Force Micrograph (AFM), and Scanning Electron Microscopy (SEM). It has been found that the diffusion of PEG in PP was greatly affected by the annealing temperature and the molecular weight of PEG. Higher temperature was in favor of PEG to diffuse in PP with fast velocity and reached diffusion equilibrium with shorter time. PEG with higher molecular weight was distributed in PP with bigger phase domains and had lower diffusivity, which resulted in its lesser enrichment on the surface of the PP blend film.
