Abstract: The invention provides a continuous process for the preparation of ethylene glycol and 1, 2-propylene glycol from starting material comprising one or more saccharides, said process being carried out in a reactor system comprising a reactor vessel equipped with an external recycle loop and said process comprising the steps of: i) providing the starting material in a solvent, via an inlet, to the external recycle loop and contacting it therein with a retro-aldol catalyst composition to provide an intermediate stream; ii) then contacting said intermediate stream with hydrogen in the presence of a hydrogenation catalyst composition in the reactor vessel; iii) withdrawing a product stream comprising glycols from the reactor vessel; iv) providing a portion of said product stream, via an outlet, for separation and purification of the glycols contained therein; and v) recycling the remainder of said product stream via the external recycle loop.

Abstract: The invention relates to a process for the production of ethylene oxide, comprising the steps of: producing ethylene resulting in a stream comprising ethylene and ethane; separating the stream comprising ethylene and ethane into a stream comprising ethylene and ethane in which stream the amount of ethylene is greater than the amount of ethane and a stream comprising ethane and ethylene in which stream the amount of ethane is greater than the amount of ethylene; producing ethylene oxide by subjecting ethylene and ethane from the stream comprising ethylene and ethane, in which stream the amount of ethylene is greater than the amount of ethane, to oxidation conditions resulting in a stream comprising ethylene oxide, unconverted ethylene and ethane; and recovering ethylene oxide from the stream comprising ethylene oxide, unconverted ethylene and ethane.
