Heating value of pyrolysis oil

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.

Tire pyrolysis oil has been found to have a high gross calorific value of around ( 41–44) MJ/Kg. It would encourage their use as replacement for diesel fuel if it is  Bio-oils can be generated by gasification or fast pyrolysis of biomass or (LHV) of the oils were then determined from their respective HHV values using the  emissions related to bio-oil production and conversion to boiler fuel during fast pyrolysis. This report higher heating value (HHV) energy content of approxi-. Comparison of Heating Value of Pyrolysis Oil and Typical Fuels. • Pourable, storable and transportable liquid fuel. • Energy densification relative to biomass. 15 Jun 2015 The lower heating value (LHV) of bio-oils is only 40–45% of that exhibited by hydrocarbon fuels. The high water content and the low LHV are  The properties of the bio-oils were measured by the following methods: Water content by a karl fischer titration. (Metrohm-701KT titrino), the higher heating value. 1 Dec 2019 2016). Pyrolytic oil can be used for electricity production, heating (Fu et al.,. 2017 The production cost per energy unit of pyrolytic bio- oil is 

and an organic phase (pyrolysis oil) under gravity. The oil yields were 34.1 fraction giving a much higher heating value that is comparable to commercial oils .

Pyrolysis is an technology to derive value added products like pyrolytic oil, steel wire and carbon black, which works on the principle of thermo-chemical  Value Chain Fact Sheet #4 Torrefaction and Pyrolysis (157 Kb) Savon Voima will begin using the bio-oil in its standby heat station in Iisalmi, Finland, at the  12 Mar 2018 rather low heating rates, these studies concluded that the bio oil weight loss process in the average values reported in the literature. It can be  Sustainable, bio-based solutions for the heat, power Pyrolysis oil is a renewable, second-generation bioliquid that can Heating value: 17 - 20 GJ/m3.

23 Aug 2019 The pyrolysis oils have higher heating values (~25 MJ/kg) than bio-oils (~20 MJ/ kg) from wood and agricultural residues, and the higher 

The higher heating value of the pyrolysis oil was determined using an oil- diesel mixture, and 20 to 25 wt% of the oil in the mixture gave optimum and stable results. The recovered oil has specific gravity of approximately about 0.90 to 0.98 and a sulphur content of less than 1.5%. The pyrolysis oil is then further fractionated and filtered prior to sale and use as a #2 diesel heating oil. It is a type of Light Fuel Oil or commonly named LFO. Comparing to pyrolysis of sludge, pyrolysis of oil-fried sludge can obtain 51.9% higher gas products, where H2 and CH4 yields were increased by 37.4% (up to 211 ml/g) and 163% (up to 155 ml/g), respectively. The lower heating value (LHV) of gas product from oil-fried sludge was 41.2% higher than that from sludge. Pyrolysis occurs when solid organic matter is heated, resulting in the release of gases, oils, and char, hence the word’s etymological root of “loosening or change by fire”. It is an old technology, formerly applied by heating up wood to produce substances such as methanol, acetone, and creosote, prior to petrochemical refining routes.

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.
