Production of ethanol from ethene

WebbPolyethylene from ethanol two step conversion. Ethene is a very simple two-carbon organic molecule (C 2 H 4) that does not have to be derived from petroleum. In fact, it can easily be produced from ethanol in a dehydration reaction. This has been known for many decades, but was not cost-competitive at low oil prices. Webb17 mars 2015 · The following report outlines the design and analysis of a process converting ethanol to chemical-grade ethylene via catalytic dehydration. This process consumers 100,000 kg/hr of 95 wt% ethanol, …
