stålgasning

Stålgasning, also known as steel gasification, is a thermochemical process that converts steel into a synthetic gas mixture, primarily carbon monoxide and hydrogen. This process typically involves heating steel in the presence of a controlled amount of oxygen or steam at high temperatures. The steel, often in scrap form, undergoes a series of reactions, breaking down into its elemental components and reacting with the gasifying agent.

The primary products of stålgasning are syngas (a mixture of CO and H2), which can be used as a fuel or as a feedstock for producing chemicals and fuels. Other byproducts can include solid residues, such as slag and ash, which may contain valuable metals or require further processing. The efficiency and specific composition of the syngas depend on various factors, including the type of steel, the gasifying agent used, temperature, pressure, and residence time.

Stålgasning is considered an advanced waste-to-energy technology. It offers the potential to recover energy and valuable materials from steel waste that might otherwise be landfilled. Research and development in this area focus on optimizing the process for different types of steel scrap, improving energy efficiency, and minimizing environmental emissions. Applications for the produced syngas include power generation, methanol production, and the synthesis of other hydrocarbons.
