WebJul 7, 2024 · What does a steam cracker produce? 3.1. Steam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial method for producing lighter alkenes (olefins), including ethene (or ethylene) and propene (or propylene) (Figure 3.2). WebThe higher cracking temperature favors the production of ethene and benzene, whereas lower severity produces relatively higher amounts of propene, C 4-hydrocarbons, and liquid products. Ethylene is synthesized by steam cracking; however, propylene is merely a by-product. Propylene is synthesized by other methods, such as propane dehydrogenation.
