摘要： The ammonia content of fuel gas in an IGCC power generation system is reduced through ammonia decomposition, thereby reducing the NO.sub.x emissions from the plant. The power generation system includes a gasifier, a gas turbine and at least one catalytic reactor arranged between the gasifier and the gas turbine. The catalytic reactor may be either a three stage or two stage device. The three stage reactor includes a first catalyst which promotes water-gas-shift, a second catalyst which promotes CO methanation, and a third catalyst which promotes ammonia decomposition. The two stage reactor includes a first catalyst which promotes water-gas-shift and CO methanation and a second catalyst which promotes ammonia decomposition. The plural catalytic stages may be disposed in a single vessel or successively disposed in individual vessels, and the catalysts may be in a pelletized form or coated on honeycomb structures. Alternatively, fluidized bed reactors may be used. The reactions are carried out either adiabatically or non-adiabatically. Heat from the water-gas-shift and CO methanation reactions may be used to generate steam, which can be injected downstream or sent to a steam turbine. Preferably, a second catalytic reactor is provided in parallel with the first reactor so that the two reactors can alternately receive fuel gas from the gasifier.

摘要： A process for producing pressurized pipeline gas wherein coal is gasified in oxygen at a relatively low pressure, typically less than 5 atmospheres, to produce a raw gas containing carbon monoxide, hydrogen, carbon dioxide, gaseous sulfur compounds and particulates. A major portion of the raw gas is cooled, cleaned and methanated to produce a pipeline quality product gas consisting essentially of methane. The remaining portion of the raw gas is cleaned, compressed and combusted to produce a high temperature, high pressure flue gas which is used to power a gas turbine and generate steam to power a steam turbine. The gas turbine and steam turbine each drive compressors for compressing the low pressure product gas to pipeline pressure.

摘要： Acid gases are removed from a coal gasification gas, followed by contacting the gas with a reduced iron catalyst at conditions selected to primarily produce methane, and some olefins together with carbon dioxide as byproduct. After separation of carbon dioxide byproduct, the gas is contacted with a nickel catalyst under methanation conditions to produce additional methane and convert olefins to alkanes to thereby produce a pipeline gas having an increased heating value.

摘要： A process for the production of a synthesis gas, capable of being upgraded to a high BTU pipeline gas, by the partial oxidation and substantially complete gasification of a carbonaceous material under CO-promoting conditions wherein the carbonaceous material, oxygen, and recycled carbon dioxide from the process are introduced into a molten salt containing an alkali metal carbonate and a minor portion of an alkali metal sulfide, the system being operated at a selected temperature and pressure between 1400.degree. and 2000.degree. F and between 1 and 100 atmospheres. The molar ratio of carbon dioxide to oxygen employed is controlled at from about 0.6:1 to about 1.2:1 to control the CO production and also to maintain the molten salt at a desired operating temperature. Sulfur and ash introduced with the fuel are retained in the molten salt. The gaseous effluent, containing a molar ratio of carbon monoxide to carbon dioxide substantially greater than one, is reacted in a water gas shift reaction, followed by removal of the carbon dioxide present in the gaseous effluent from the shift reaction to produce the synthesis gas, capable of being reacted further under appropriate conditions to produce pipeline gas, methanol, ammonia, or gasoline. At least a portion of the removed carbon dioxide is recycled for admixture with the oxygen to form the feed gas to the molten salt containing the carbonaceous material.
