Size of ground biomass particles is significant logistically

by Oladiran Fasin

As part of preparing biomass for conversion into biofuels, biomass is ground through mills such as a hammer mill (Figure 1) or a knife mill. The ground biomass particles are then fed into conversion vessels and/or stored in hoppers that are often attached to storage vessels (Figure 2). Creating a steady flow of the biomass particles out of the hopper is a significant issue for processing and conversion. Often, biomass flow from storage containers will be disrupted …

What are the differences between biofuels, biopower, and bioproducts?

These terms refer to three generally different end uses of biomass based products. “Biofuel” is short for “biomass fuel,” a term used for liquid fuels produced from biomass (generally transportation fuels), such as ethanol, bio-oil, and biodiesel. “Biopower” refers to biomass-fueled power systems that generate electricity or industrial process heat and steam, such as combined heat and power (CHP) systems. “Bioproduct” is short for “biomass products” and can be used to describe a chemical, material, or other (non-energy) product such …
