Industrial Application Of Domestic Acrylic Acid Catalyst In The 80 Kt/a Plant

The core technology of the oxidation of propylene to acrylic acid in the gas phase is a high performance catalyst.Domestic acrylic acid catalyst has made significant achievements in the development.By the test of domestic acrylic acid catalyst in the 80 kt/a device,we determinate mainly the process condition of the catalyst of the propylene oxidized to acrolein and acrolein oxidized to acrylic acid of the conversion of propylene?the yield of acrylic acid?reaction temperature?reaction press and so on.Through evaluation,we determinate mainly the conversion of propylene:?96%,the yield of acrylic acid:>85%.The quality of acrylic acid within the scope of the target control,meets the needs of the 80 kt/a plant.
