Entrainment flow gasification, also known as entrained flow gasification or EF gasification, is a process used to convert coal, biomass, and other carbon-containing materials into synthesis gas (syngas), which is a mixture of hydrogen and carbon monoxide. This process is widely used in the production of electricity, chemicals, and transportation fuels.

The entrainment flow gasification process involves the injection of a high-velocity gas stream into a reactor, which carries with it particles of the carbon-containing material. The gas stream and particles are heated to a high temperature, typically between 1400°C to 1600°C, above which the water vapor in the gas stream is broken down into its hydrogen and oxygen components. The carbon in the material is then reacted with the oxygen to produce carbon monoxide.

The EF gasification process offers several advantages over other gasification processes, including higher conversion efficiency, lower capital costs, and greater flexibility in terms of feedstock. The high gas velocity and temperature involved in EF gasification also enable the combustion of more material with less air, reducing the energy required for the process.

Entrained flow gasification is used in a variety of applications, including power generation, the production of fertilizer and chemicals, and biofuels. The process is carried out in various types of reactors, including circulating fluidized bed (CFB) and fluidized bed gasifiers. Additionally, entrained flow gasification has been the subject of ongoing research and development to improve its efficiency and environmental performance.
