ChemInform Abstract: Make Ethylene from Ethanol.

Abstract

Ein Verfahren zur Herstellung von Äthylen aus Äthanol ist dann konkurrenzfähig, wenn, wie in ölarmen Entwicklungsländern, Äthylen aus Ölvorkommen nicht zur Verfügung steht.

Study of operating variables in the transformation of aqueous ethanol into hydrocarbons on an HZSM‐5 zeolite

“…The ethanol obtained by fermentation of vegetable biomass and agricultural residues (a renewable and relatively abundant raw material) is an interesting alternative in developing countries wishing to reduce their dependency on petroleum as well as revitalize both agricultural activity and the local fermentation industry 1, 2…”

Ethylene from Renewable Resources

“…The catalyst used in the earlier industrial process was γ -alumina (Al 2 O 3 ) [21]. This catalyst requires a relatively high temperature for dehydration (450 • C) and results in a relatively low yield of ethanol, approximately 80%.…”

Process Modeling and Simulation of an Industrial-Scale Plant for Green Ethylene Production

“…Ethylene can also be used as a raw material for the production of polymers, such as polyethylene, polyvinyl chloride, and polystyrene. Additionally, ethylene production is one of the indicators of the level of development of petrochemicals in countries all around the world . However, inevitably, fossil fuels will continue to face problems related to their reserves’ increasing scarcity, and the end of their conventional extraction is inexorable, besides the problems associated with geopolitical and environmental issues.…”

“…Commercial production of ethylene from ethanol started before World War I, when ethylene was used as a refrigeration fluid, at the Elektrochemischen Werke in Germany . ICI built an ethanol-to-ethylene plant in England in the 1930s, where it produced polyethylene, and many other plants followed in different countries with different uses for ethylene, such as PVC, SBR, and polystyrene, as well as ethylene oxide and monoethylene glycol (MEG) . The early plants operated with complex reactors because of the need to provide heat to the endothermic reaction.…”
