The primary method for olefin production is steam cracking. This process involves the thermal decomposition of hydrocarbons, primarily naphtha or ethane, at high temperatures (800-900°C). The products of steam cracking include a mix of olefins, aromatics, and other hydrocarbons. Catalysts are not typically used in steam cracking, but they are essential in subsequent processes that modify and refine the olefins produced.
