Cracked steam is typically produced through a process called steam reforming, where high-temperature steam is passed over a catalyst, usually a metal oxide, to facilitate the decomposition reaction. The reaction is endothermic, meaning it absorbs heat energy, and requires temperatures above 700°C (1,300°F).

H2O (steam) → H2 (hydrogen) + 1/2 O2 (oxygen)

The steam reforming reaction is as follows:

CO2 (carbon dioxide) + H2 (hydrogen) → CO (carbon monoxide) + H2O (steam)

Cracked steam, also known as cracked gas or synthesis gas, is a mixture of gases produced by the thermal decomposition of steam (H2O) into its component elements, hydrogen (H2) and oxygen (O2), and carbon monoxide (CO). This process is known as steam cracking.

In conclusion, cracked steam, or synthesis gas, is a versatile gas mixture with a wide range of applications across various industries. While there are challenges associated with its production and use, ongoing research and development aim to improve the efficiency, scalability, and sustainability of cracked steam production.

However, in the presence of a catalyst and at high temperatures, the oxygen produced reacts with carbon-based materials, such as methane or coal, to produce carbon monoxide:
