The ash sample for this study was collected from a commercialscale fixedbed gasification unit in the eastern part of India. This coal gasification plant (CGP) has a syn gas production capacity of 2,25,000 Nm 3 /h with a coal requirement of around 270 tons/hr. The plant was built based on Lurgi, Germany SLTC, S. Africa technology.
A fluidized bed gasification pilot plant has been designed and installed at CSIRCentral institute of Mining and Fuel Research to cater the present need of technology development with high ash coals. The activity was also included under clean coal technology development programme under 11th Five year plan, Govt. of India.
A wide range of research, development, and demonstration (RDD) activities are being conducted to improve the fuel and product versatility, carbon footprint, efficiency, and economics of gasification processes. Current work focuses on gasification of mixed feedstocks including wastes, waste coal, and biomass, for production of clean hydrogen and sustainable fuels and chemicals, thereby ...

The entrainedbed coal gasification process is the cleanest and most efficient coal gasification technology (Fan 2013; Liu et al. 2010; Wang 2014). At present, the entrainedbed coal gasification process is widely used in IGCC power stations over 250 MW (Zhang and Yang 2019). Compared with fixedbed and fluidizedbed gasifiers, entrainedbed ...

Cogasification (COG) is a cleancoal technology that uses a binary blend of coal and biomass for generating the product gas; it is environmentfriendly since it emits lesser quantities of pollutants compared to the coal gasification process. Although coals found in many countries contain high percentages of ash, cogasification studies involving such coals, and the process modeling thereof ...
Fluidised bed gasification is being evaluated by the CSIR as a potential fine coal gasification process for incorporation into future IGCC plants. A suite of four South African coals has been identified as being possible fuels for power stations which would operate for three or four decades, towards the middle of this century.
Airblown plants are less amenable to chemicals production applications and to high levels of precombustion CO 2 capture than oxygenblown gasifiers; 2. a gasification plant—for converting solid or liquid hydrocarbon fuels into synthesis gas (syngas); 3. a syngas gas cleanup system; and. 4. a combinedcycle power plant.

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the Obviously ...
The article presents an experimental laboratory setup used for the empirical determination of the gasification of coal samples in the form of solid rock, cut out in the form of a cylinder. An experimental laboratory set enabled a series of experiments carried out at 700 °C with steam as the gasification agent. The samples were prepared from the coal seam, the use of which can be planned in ...
Coal gasification is a thermochemical process in which heat and pressure break down coal into its basic chemical constituents. The resulting "syngas" is comprised primarily of carbon monoxide and hydrogen, and occasionally other gaseous compounds. Syngas can be used for electricity production, used in energyefficient fuel cell technology ...
