Synthetic Natural Gas• Synthetic natural gas, is a fuel gas that can be
produced from fossil fuels such as lignite coal or from biofuels around 85% methane,
• Syngas is an abbreviation for synthesis gas, which is a mixture comprising of carbon monoxide, carbon dioxide, and hydrogen.
• The syngas is produced by gasification of a carbon containing fuel to a gaseous product that has some heating value.
• Clean Synthesis Gas is free of acid gases.
• Clean Synthesis Gas is widely applicable.
SNG Offers
● Energy efficient biofuel production
● Second generation biofuel
● Transportation, heating and power generation fuel
● Low emissions
● Existing infrastructure
● Integration with Wind, Water Solars through Renewable Power Methane.
Low BTU Gas
• 150-300BTU/ft3 Basic Syngas Produced by air fed gasifier which contains 35-50% nitrogen, but suffices as normal industrial heating fuel
•300-500BTU/ft3 higher grade syngas produced by ooxygen fed Gasifier which requires a dedicated oxygen plant
High BTU SNG
•1000-1400BTU/ft3 this gas requires a shift reactor to upgrade the Gas
Catagories of Coal Syngas
Electricity Generation
● SNG works in existing natural gas generators and turbines
● Can provide flexible low capital cost biomass power

Uses of Syngas
Uses of Synthetic Natural Gas
• Transportation• Electricity generation• Domestic • Industrial (Ammonia Manufacture)
Natural gas buses are widely used
● 150 units in CanadaSource: Marbek (2010)

Coal Gasification Technologies
• Basic Overview of gasification• Coal or other fuels• Oxidation carefully controlled• H2, CO2, CH4, other products • H2 can be purified • Ash/slag leftovers
• 3 types of gasifiers• Moving bed• Fluid Bed• Entrained Flow
• Underground Coal Gasification• Vertical wells and pathway creation• Controlled retraction injection point
