WebSteam Cracking. Steam cracking is a nonselective process that produces many products from a variety of feedstocks by free-radical reactions. An excellent treatise on the fundamentals of manufacturing ethylene has been given (44). Eeedstocks range from ethane on the light end to heavy vacuum gas oil on the heavy end. WebA catalyst is a substance that can increase the rate at which a chemical reaction occurs, without itself being changed. Because it has the potential to produce very selective results, such as the cracking of high-boiling petroleum fractions to gasoline, a catalyst can give a particular process a competitive advantage.
