  • Hydrogen production - Wikipedia

    Hydrogen production is the family of industrial methods for generating hydrogen gas. As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas and other light hydrocarbons, partial oxidation of heavier hydrocarbons, and coal gasification. Other methods of hydrogen production include biomass gasification, no CO 2 emissions methane pyrolysis ...

  • Coal Gasification - an overview | ScienceDirect Topics

    Coal-gasification is a very important process involved in the production of chemical fertilizers, energy and many intermediate chemical products. As has been mentioned, the Koppers–Totzek coal-gasifier is an instance of the earliest application of impinging streams, applied industrially as early as 1952 [ 4 , 145 ] although the term ...

  • Coal Bed Methane (CBM) - Definition and Use

    Coal bed methane (CBM) refers to a reserve of natural gas stored in coal seams. It is an unconventional form of natural gas. In this article, we’ll discuss Coal Bed Methane, its uses and challenges associated with it in relevance to the IAS Exam.. This topic is important for the UPSC Examination for General Studies Paper 3 Environment and Ecology as CBM is also seen as a clean energy source.

  • Boiler Efficiency - an overview | ScienceDirect Topics

    Coal is dried in a fluidized-bed reactor with oxidizing environment, which is a key element in promoting stability. The process operates at low temperature (315 °C) and no outside source of heat is required as 6–8% of the feedstock coal is burned in the process. The finished product is stable with 0.5% moisture.
