The gas composition affects investment of the coal to hydrogen process and CO 2 emission [8]. There are three main types of gasifiers: fixed bed gasifier, entrained flow gasifier [9] and fluidized bed gasifier [10]. As one of the entrained flow gasifiers, the Shell gasifier has been applied in the coal to hydrogen process.
