To choose the pyrolysis liquid as a substitute for fossil oil, some properties such as heating value (HV), density, viscosity, Cetane number, and flash point are taken into account. The principal measurement of energy in a substance is generally known as its calorific value (CV) or heating value (HV). 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 taken into account in its handling and use. If poorly produced the oil has a tendency to age (degrade). Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel under investigation as substitute for petroleum. It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C with subsequent cooling. Pyrolytic oil is a kind of tar and normally contains levels of oxygen too high to be considered a hydrocarbon. This high oxygen content results in non-volatility, corrosiveness, immiscibity with fossil fuels, thermal instability, and a tendency The high content of oxygenated compounds and the water content, and a low heating value of pyrolysis oil, make the direct co-processing of oil itself in standard refinery units problematic. Several pyrolysis process modifications are currently being studied to obtain the oil product with the better properties. 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. This Engine has successfully been adapted to enable fuelling of pyrolysis oil. Turbines. The first gas turbine to operate on pyrolysis oil was developed by Orenda based on a 2.5-MWe Class GT2500 engine designed and manufactured by Zorya-Mash-proekt in the Ukraine.

High values of carbon content and heating value in biochar made it comparable to coal and coke used in blast furnaces. Due to requirements of blast furnace,

Cooling and condensation forms a dark brown liquid, which has a heating value about half that of conventional fuel oil. The essential features of a fast pyrolysis process are: very high heating and heat transfer rates, which usually require a finely ground biomass feed; and rapid heating up to 500°C and then rapid cooling of the pyrolysis vapours to give the main product – bio-oil. After further refining, pyrolysis oil can be certified into many applications, among them, food flavors and food aromas markets. As an additional benefit, quality biochar and heat is obtained, which can be an added value to the project. 4. Wood vinegar production The calorific value of pyrolysis oil was determined by using AC-350 Automatic Bomb Calorimeter. The calorific value used in the study is presented as higher heating value (mg kg-1). The products yield of char and bio oil were calculated based on percentage as a fraction of 100 for final weight of products to the original biomass weight prior to the pyrolysis process. The distribution of products between liquid, char, and gas on a weight basis for this “slow” pyrolysis is approximately 30%, 35%, and 35% respectively, whereas under “fast pyrolysis” conditions the product distribution is dramatically altered and shifts the distribution primarily to a liquid bio-oil product. One of the current methods of converting pyrolysis oil and its aqueous phase into more useful biofuels with higher heating value is by the steam reforming technique. Currently, most of the interest in pyrolysis heating rates and higher temperatures than slow pyrolysis and is endothermic (it does not release heat). The ideal conditions for fast pyrolysis involve rapid heating rates (> 400ºF per second) and temper-atures usually in excess of 1,000ºF. Due to its short After further refining, pyrolysis oil can be certified into many applications, among them, food flavors and food aromas markets.
