How is ethanol prepared from ethene
WebThe ethanol is then distilled and dehydrated, then blended with about 2% denaturant (such as gasoline) to render it undrinkable. It is then ready for shipment. The stillage is sent through a centrifuge that separates the solids from the solubles. These co-products eventually become distillers grains, as well as corn distillers oil. WebEthanol can be synthesised by the hydration of ethene. Ethene is a by-product of the cracking of hydrocarbons and is a valuable feedstock for making many chemicals. The …
