Ethylene Use and Manufacturing

Methods of Manufacturing

Industrial ethylene production methods include petroleum hydrocarbon cracking, ethanol catalytic dehydration, and coke oven gas separation. Due to the abundant oil and natural gas resources, mass production of ethylene has low cost and good quality. Therefore, a large amount of ethylene is mainly produced by petroleum cracking. Ethanol catalytic dehydration is limited to occasions where a small amount of ethylene is provided for fine chemicals.

Uses

Oxyethylene welding and cutting metals; manufacture of alcohol, mustard gas, and many other organics.manufacture of ethylene oxide (for plastics), "Polythene", polystyrene and other plastics.Plant growth regulator; used commercially to accelerate the ripening of various fruits.
