Biomass has higher h/c ratio than coal
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). WebCoal takes millions of years to form. Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. 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.
