Production of hydrogen based on combined torrefaction and gasification process

Fossil fuels are commonly used and highly dependent in worldwide market as the main energy sources despite of any other sources but this source is non-renewable energy. Hence, biomass is becoming the best effective alternative energy source to replace the fossil fuels in the future due to its abunda...

Different types of biomass; which are torrefied and non-torrefied biomass usually have a different impact on the production of high level of hydrogen gas which is useful in generating energy.

Based on this pretreatment, the torrefied biomass is then used as an input to this gasifier. It is expected that the torrified biomass will gives higher performance due to the higher level production of hydrogen gas compared to the non-torrefied biomass because torrified biomass undergoes torrefaction process before proceed to gasification process will have a lower moisture content and higher heating value. 2016-12 Undergraduates Project Papers NonPeerReviewed pdf en http://umpir.ump.edu.my/id/eprint/22560/1/Production%20of%20hydrogen%20based%20on%20combined%20torrefaction%20and%20gasification%20process%20-%20Table%20of%20contents.pdf pdf en http://umpir.ump.edu.my/id/eprint/22560/2/Production%20of%20hydrogen%20based%20on%20combined%20torrefaction%20and%20gasification%20process%20-%20Abstract.pdf pdf en http://umpir.ump.edu.my/id/eprint/22560/3/Production%20of%20hydrogen%20based%20on%20combined%20torrefaction%20and%20gasification%20process%20-%20Chapter%201.pdf pdf en http://umpir.ump.edu.my/id/eprint/22560/4/Production%20of%20hydrogen%20based%20on%20combined%20torrefaction%20and%20gasification%20process%20-%20References.pdf Nuralyaa, Ibrahim (2016) Production of hydrogen based on combined torrefaction and gasification process.
