The three processes are very similar, but differ in details of the gas production and heat recovery. The gas used for reduction can be either natural gas or coke oven gas. Alternatively the gas can be made by gasifying coal or biomass. When these technologies are based on a coal gasifier they contain a CO 2 removal step. This means these ...
