WebMar 27, 2024 · Carbon materials are widely used in catalysis as effective catalyst supports. Carbon supports can be produced from coal, organic precursors, biomass, and polymer wastes. Biomass is one of the promising sources used to produce carbon-based materials with a high surface area and a hierarchical structure. In this review, we briefly discuss the … WebTorrefaction of biomass, e.g., wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates its potential for organic decomposition.
WebJan 30, 2011 · Abstract. Colombian coffee industry produces about 0.6 million tons of husk (CH) per year which could serve as feedstock for thermal gasification to produce gaseous and liquid fuels. The current paper deals with: (i) CH adiabatic gasification modeling using air-steam blends for partial oxidation and (ii) experimental thermogravimetric analysis ... WebActivated carbons (ACs) with a highly developed porosity have been prepared from a lignocellulosic precursor (coffee husk) for environmental pollutant adsorption. Characterization results show that these materials exhibit a high amount oxygen groups and high specific surface area with micro mesopores. From SEM results we can see the …
