Guide to energy from biomass
Biomass is biological material derived from living organisms , or organisms that have been recently. Generally it refers to plants or materials of plant origin that are specifically called lignocellulosic biomass . For the purposes of renewable energy production , the biomass can be used directly by combustion for the production of heat, or indirectly, after conversion to various forms of biofuel . The conversion into biofuel can be accomplished with various methods which are classified into: thermal, chemical, biochemical. Let’s see what it is in this guide!
Historically, humans have begun to harness the energy from biomass when they started to turn the wood to make fire. Even in modern times, biomass is the only source of fuel for domestic use in many countries in the developing world.
Biomass is any organic matter produced based on carbon, hydrogen and oxygen. Laproduzione in the world is estimated 146 billion tons per year, composed mostly of the growth of wild plants. Based on the sources of biomass, biofuels are basically classified into two broad categories. biofuels first generation, derived from sources such as starch from corn and sugar cane , etc.
The sugars in these biomasses are fermented to produce ethanol, a fuel, alcohol-based, that can be used directly in a fuel cell to produce electricity or to serve as an additive to gasoline. However, the use of resources to food base for the production of fuel not just exacerbates the problem of shortage of food. Biofuels say second generation instead use non-food biomass sources based on agricultural waste and the waste cities. Sitratta mainly lignocellulosic biomass, which is why they are not edible, so they represent a low waste of resources for many industries. While Being favorite, the large-scale production of biofuels of the second generation has not yet been achieved due to technological problems. these Problems mainly derived from inertia chemistry and structural rigidity of lignocellulosic biomass .
The legnoresta currently the largest source of energy from biomass, for example, it includes forest residues (such as dead trees, branches and tree stumps), yard waste, wood chips and even municipal solid waste. Biomass includes plant or animal matter that can be converted into fibers or other industrial chemicals, including biofuels. The biomass industrial can be grown through many types of plants, including: hemp, corn, poplar, willow, sorghum, sugar cane, bamboo and a variety of tree species ranging eucalyptus oil palm. energy produced through the wood is derivable from lignocellulosic biomass (second generation biofuels) as fuel. This is feasible through the use of wood as a fuel collected directly, or through the collection of its waste. the More great source of energy from wood is given by the “black liquor”, a waste product of the transformation processes of the paper industry Dilegno pulp, paper and cardboard.
