of energy to offset the increase in the oil demand and the environmental that the carbon content is slightly lower than in the bio-oil obtained from wood (55 to The higher heating value (HHV) of pyrolysis oil is 16-23 MJ/l compared to fossil fuel which is 37 MJ/l. Pyrolysis oil has a low pH value of around 3, which must be Bio-oil is a promising alternative source of energy which can be produced from empty Moreover, due to the high oxygen content, bio-oil is easily hardened on The U.S. Department of Energy's Office of Energy Efficiency and Renewable WORKSHOP REPORT: Pyrolysis Oil Technical Information Exchange 5.2.3 Challenge #3: Better correlating corrosion with percent oxygen content and functional. The demand of renewable energy had created a foundation for biofuels to grow. Bio oil as secondary biofuels is produced from pyrolysis process using biomass as Finally, we take a brief look at some processes including catalytic pyrolysis process that aim to valorize bio‐oil by conversion to higher value liquid fuel products. 2.

Neither carbon content nor heating value of char was influenced by bio-oil impregnation. Energy yield also showed improvement by increasing bio-oil recycling

Some energy crops such as switchgrass and Miscanthus, as well as algae, can also be used as feedstock for pyrolysis oil, which can then be further processed into transportation fuels. There is a catch, however: pyrolysis oil is highly acidic and corrosive. Only a few percent of chlorine and potassium are carried in the pyrolysis gas and bio-oil at a pyrolysis temperature of less than 700 °C (Jensen et al., 1999). About 40% of the energy is at a temperature of 700 °C in the gas fraction. Fifty percent of the energy remains in the biochar in slow pyrolysis at 400 °C. The yield of upgraded oil is typically between 30 and 68 wt% with oxygen content between 0.3 and 0.6 wt% [ 14, 74, 75 ]. Hydrogen consumption is typically close to 600 NL/kg-pyrolysis oil and coke formation <13 wt% [ 14, 74, 75 ]. • Care fully controlled pyrolysis reaction temperature of around 500 ºC and vapour phase temperature of 400-450 ºC, • Short vapour residence times of typically less than 2 seconds, and. • Rapid cooling of the pyrolysis vapours to give the bio-oil product.

Bio-oil is a promising alternative source of energy which can be produced from empty Moreover, due to the high oxygen content, bio-oil is easily hardened on

Syngas can be used in place of natural gas or converted with catalysts to ethanol. There are two types of Pyrolysis systems. Fast Pyrolysis optimizes bio-oil production by increasing the rate of pyrolysis temperature to 1000°C/second. This process yields approximately 60-70% bio-oil, 15-25% bio-char, and 10-15% syngas.

products industry is about 613,000 green tons [8], which has an energy content equivalent to almost 2 million barrels of oil. In this study, fast pyrolysis of hog fuel energy feedstock security as opposed to the present system. Though bio-oil seems to be a promising replacement for fossil fuels, its water content and other Thus pyrolysis of biomass produces three products: one liquid, bio-oil, one solid, of bio-oil or bio-char can provide all the necessary energy to drive the reaction. It has a fuel value that is generally 50 - 70% that of petroleum bases fuels and

The Heating Value of pyrolysis oil is about half the value of diesel. Engine test facility. The basis of the BTG's test set-up is a one-cylinder, 20 kWe diesel engine.

The high oxygen content results in a low energy density (heating value) that is less than 50% of that for conventional fuel oils and immiscibility with .
