In the Shell gasification process, coal is crushed and dried and then fed into the Shell gasifier as a dry feed. The gasifier, as shown in Figure 8, is an oxygenblown, waterwall gasifier eliminating refractory durability issues. It is good for wide variety of feed stocks, from pet coke to lowrank coals and has been run on biomass as well.
