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 …
Woody biomass is converted into useful forms of energy (i.e. solid, liquid, or gaseous fuels) as well as useful products (e.g. polymers, bio-plastics, char, pellets, and acids) using a number of technological processes. Thermochemical processes depend on the relationship between heat and chemical action as a means of extracting and creating products and energy. This fact sheet briefly covers some of the more important thermochemical conversion and production processes used for obtaining bio-based energy and products from woody biomass.…
Woody biomass is an abundant and readily available resource that historically has not been used much except by forest products manufacturers as an internal energy source at their facilities, although many such manufacturers have also been able to produce excess electric power for sale to the grid. Whereas commercial-scale production of transportation fuels is still in early stages of development, technologies are already well-developed for producing heat and electricity from biomass in firing or co-firing in boilers and in gasification …
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 …
