Webb14 apr. 2024 · An operando DRIFT-MS system (Diffuse Reflectance Infrared Fourier Transform Spectroscopy coupled with Mass Spectrometry) was designed and set up to study the oxidative steam reforming of ethanol reaction (OSRE). This reaction involves the mixture of water, ethanol and oxygen to produce mainly hydrogen, which is a rather … Webb13 maj 2024 · In the hydration of ethene, ethanol is made by passing ethene and steam over a catalyst. Water is added to ethene, this is known as hydration.
