Introduction of Coal Gasification Technologies

2018-12-4 · Coal water slurry gasification has been a mature technology presently. It is widely used in many coal-syngas-chemical projects. However, high requirements for coal quality limit the further promotion. Typical raw gas composition OMB GE ITEM mol% ITEM mol% H2 36.611 H2 36.323 CO 44.665 CO 38.284


2019-5-6 · Dry Feed vs Slurry Feed Coal is typically fed into a pressurized gasifier either pneumatically as a dry solid or pumped as coal-water slurry. Slurry-fed feed systems have a lower capital cost, but result in less efficient conversion of coal to syngas (referred to as the "cold gas efficiency" of the gasifier).
