Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
Biomass has higher h/c ratio than coal
Did you know?
WebThe atomic H/C ratio of torrefied biomass under an inert atmosphere tended to be higher than what was obtained under an oxidizing atmosphere for the same temperature conditions (Lu et al. 2012). This result was due to the thermal degradation of elements such as hydrogen and oxygen, associated with the decomposition of wood constituents. WebJul 7, 2024 · The carbon content of biomass is considerably lower than that present in coal. On the other hand, in comparison with coal, oxygen content in biomass is quite high. Thus, the lower C to O ratio and C to H ratio of biomass in comparison with coal will directly affect the reactivities and heating values of coal-biomass blends (Munir et al. 2009).
