Energy Hope:Bio-fuel production by fast pyrolysis method

Current global fuel available is based on fossil fuels (oil, natural gas, coal), but with the increasing world population, the energy consumption per capita and the evidence of global warming, the necessity for long-term alternative energy sources is apparent.Oil and gas experts believes that exhaustation of fossil fuel is not a distant possibility rather than the near future catastrophe.A judicious picture holds that the oil production will peak in 2025, but will cried off by 2115. The greater part of scientists argues that the world oil production has either sharped already or will be peaking in few years.

Higher genera plants supplement the major share in global lignocellulosic biomass, now consider as renewable reserve intended for the production of biofuels through chemical or biological engineering. Among the biomass to energy conversion processes, pyrolysis i.e. biomass heated at the limited oxygen supply, is mostly applicable solution in the present.

During the pyrolysis process biomass become converted to the main product; bio-oil, biochar, biogas.Biochar is oxygen-limited produce of pyrolysis from organic biomass, which is porous substance with charcoal like appearance. Biochar is now been considered as recalcitrant carbon reservoir.Biochar has been widely used in nutrient retention in soil as well as a soil fertility enhancing agent.

The concerns have boosted the importance of research for alternatives to fossil derived products. Densification of biomass into briquettes, pellets, cubes etc. is a method employed for increasing the intrinsic density of materials  for more constructive employment . Pelletizing is another method of upgrading biomass fuel. Unlike briquettes, pellets are smaller in size and have a smaller diameter. They also require higher pressure and heat to produce. However, compared to briquettes, pellets are suitable for a wider range of applications. Traditionally, pellets are produced from woody biomass such as sawdust, wood chips and forestry residue. Pellets can also be prepared from a wide range of agricultural and waste biomass material.
