Shell Coal Gasification
Shell Coal Gasification : Also called SCG and SCGP. A coal gasification process in which powdered coal is reacted with oxygen and steam at high temperature and pressure. The high temperature causes most of the ash to melt and flow down the reactor wall into a water-filled compartment. The product gas is mainly a mixture of carbon monoxide and hydrogen, suitable for the synthesis of ammonia, methanol, and hydrocarbons
