  • Methods for integrated natural gas purification and products produced therefrom
    Patent number: 9676695
    Abstract: A method is disclosed of coupling and integrating natural gas recovery and separation along with chemical conversion. The method can comprise extracting at least one natural gas component. Non-limiting examples of the extracted component include ethane, propane, butanes, and pentanes. The method can also comprise contacting a natural gas stream with a catalyst under conditions that selectively convert at least one component into at least one product, such as ethylene, acetic acid, polyethylene, vinyl acetate, ethylene vinyl acetate, ethylene oxide, ethylene glycol, and their derivatives, propylene, polypropylene, propylene oxide, propylene glycol, acrylates, acrolein, acrylic acid, butenes, butadiene, methacrolein, methacrylic acid, methacrylates, and their derivatives, which can then be separated from the remaining components.

  • Processes for the manufacture of acrolein derivatives
    Patent number: 6187963
    Abstract: Processes are disclosed for the conversion of propylene to an acrolein derivative by converting propylene to acrolein and converting acrolein to the acrolein derivative. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise, propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.

  • Processes for the manufacture of acrolein
    Patent number: 6166263
    Abstract: Processes are disclosed for the conversion of propylene to acrolein in the presence of propane. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise, propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.
