By Homologation (e.g., Forming Ethanol From Methanol, Etc.) Patents (Class 568/902.2)
  • Process for recovering the methanol contained in a liquid hydrocarbon feed
    Patent number: 6679975
    Abstract: The present invention aims to isolate the azeotropes formed in a distillation column (B1) by methanol, propane and butane. The azeotropes are then liquefied in heat exchanger (E2) and mixed in contactor (M1) with water in order to dissolve the methanol in water. The mixture is then fed into a decantation tank (D2) to separate the aqueous phase from the liquid hydrocarbon phase. Finally, an aqueous phase containing methanol is discharged and the methanol-depleted hydrocarbon phase is recycled to distillation column (B1) as reflux.

  • Synthesis method of chemical industrial raw material and high-octane fuel, and high-octane fuel composition
    Patent number: 6323383
    Abstract: A process for the synthesis of chemical industrial feedstock and high-octane fuel, wherein calcium phosphate which is controlled in the molar Ca/P ratio and/or one which contains an activating metal (M) at a molar (Ca+M)/P ratio of 1 to 2 is used as the catalyst and ethanol is used as the feedstock.
