Koppers-Totzek process
Quick Summary
The Koppers-Totzek process is a successful entrained-flow gasifier technology used for coal gasification. This process converts coal into combustible gases, primarily carbon monoxide and hydrogen, known as synthesis gas.12
The Koppers-Totzek gasifier operates at high temperatures (1,600–1,900 °C) and atmospheric pressure. Pulverized coal is blown into the gasifier with steam and oxygen. Due to the small particle size of the coal and the high temperatures, the reaction is rapid, with a residence time of about one second. This allows almost any type of coal to be gasified. The process effectively cracks tars and oils at high temperatures, producing a clean synthesis gas. The ash melts and is removed as slag. The resulting synthesis gas is mainly used for ammonia manufacture.1
