Pyrolysis process using abundantly available biomass waste fabric is a promising, renewable, and sustainable energy supply for bio-oil production. In this study, the pyrolysis of waste biomass determines the highest yield of diverse parameters of material type, temperature, reactor, method, and analysis used. From the differences in the parameters stated above, there is an opportunity to select the proper parameters to get the desired nice and quantity of bio-oil and the very best bio-oil yield. The maximum yield of each bio-oil product for pyrolysis primarily based on the above parameters was 68.9%; 56.9%; 44.4%; 44.16%; 41.05%; 39.99%. The bio-oil made out of pyrolysis was changed into analyzed using GC-MS, ft-IR, NMR, TGA, SEM, Thermogravimetric analysis, HHV, FESEM evaluation methods and the substances used had been plastic, seaweeds, oat straw, rice straw , water hyacinth, timber sawdust, sawdust, microalgae.

Burning of post-harvest non-edible agro residues (biomass) are the major source of environmental and soil pollution, affecting the lives of millions of people, especially in certain demography of developing countries like India. Non edible agro residues contain toxic structural constituents, making it unsuitable for cattle feed. However, due to its cellulosic and lignocellulosic constituents, it has the potential to be used as a promising feedstock to develop value added energy products. Authors in this review paper have comprehensively reviewed the technological aspects related to conversion of agro residues into value added energy products like bio-oil, bio-char, and pyro gas. Various non-edible agro residues like Cotton stalk, castor stalk, Maize stalk, Rice straw, Rice husk, Corn cob, Sugarcane bagasse, and wheat straw etc., have been reviewed for its potential as feedstock material for thermo chemical conversion to obtain energy products like bio-oil, bio-char, and pyro-gas.

Effect Of Temperature And Particle Sizein Biomass Pyrolysis And Properties Of Bio Oil
Research India Publication, 2015
In this work pyrolysis of biomass waste namely kiker seeds, vellikathan seeds and coconut shell were identified and experimented for pyrolysis. The main work is to study the use of pyro oil as fuel in diesel engine experimentally. In the first phase of this project extraction of pyro oil was done from the biomass through pyrolysis. The physical properties of these pyro oils were studied by conducting experiments in the fuels laboratory. The various properties such as viscosity, flash point and density were tabulated. The physical properties such as viscosity of coconut shell, kiker seeds, and vellikathan were found as 42, 39, 37 centistokes respectively. The flash points of these oils were found as 87°C, 107°C and 102°C. The densities of these oils were found as 1098 kg/m 3 , 1224kg/m 3 and 1232kg/m 3 respectively. It may be noted that pyro oil yield increased with the increase in particle size up to 450µm, further increase in particle size decreased the pyro oil yield.The effect of temperature on bio oil yield, the results showed that the increase in temperature of the pyrolysis process above 550°C should be reducing the amount of yielding quality of the fuel.
Effect of Temperature on the Bio Oil Yield from Pyrolysis of Maize Stalks in Fluidized Bed Reactor
Fast pyrolysis is used to convert the waste biomass into liquid fuel which has a benefit of storage and transportation with the potential as a fossil oil substitute. Pakistan is an agricultural based country producing about 69 million tons of agricultural residues such as wheat straw, rice straw, cotton stalk, maize stalk and sugar cane trash etc per year. Fast pyrolysis experiments are carried out in a bench scale fluidized bed reactor. The effect of temperature on the bio oil yield is studied. Bio oil yield increases with the rise of temperature from 361 to 510°C and yield of char decreases whereas that of gas is also increased. The maximum bio oil yield is 42 wt% at the optimum temperature of 510°C. Chemical composition of bio oil produced from the pyrolysis of maize stalks is determined using GC-MS and FTIR analysis whereas co-products such as uncondensable gas and charcoal are characterized using GC analyzer and bomb calorimeter

Temperature and the heating rate has a positive correlation with the bio-oil yield. Temperature is the parameter with more influence in pyrolysis process of biomass.
Fuel Properties and Chemical Compositions of Bio-oils from Biomass Pyrolysis
Pyrolysis of biomass is a promising alternative route for producing energy and chemical feedstock. This research proposes to investigate effect of pyrolysis temperature on product yields and the determination of their physicochemical properties. Slow pyrolysis of biomass (cassava pulp residue, palm shell and palm kernel) was performed in a fixed bed reactor. Palm kernel pyrolysis provided the highest liquid yield (54.34 wt%) at 700°C. Fuel properties of bio-oils are viscosity at 40°C, 1.46-58.72 cSt (mm 2 /s); pH, 2.8-5.6 and heating value, 14.92-40.00 MJ/kg. The boiling range distribution of dewatered palm kernel oil was closest to that of diesel oil while its heating value approached that of fuel oil.
Investigation of biomass pyrolysis on non-catalytic process for bio-oil production
International Proceedings of Chemical Biological and Environmental Engineering, 2012
In this study, we have focused on surveying the ability to produce liquid fuels (bio-oil) from biomass by pyrolysis method without catalyst. The influence of process parameters on the yield of liquid biomass fuels has been carried out. The results showed that the experimental conditions through a thermal pyrolysis with fixed bed and non-catalyst, recovery of bio-oil are depended on their parameters, such as: pyrolysis temperature, size of the biomass materials and partial pressure of nitrogen gas in environmental pyrolysis reaction. Effects of temperature impact significantly on the pyrolysis process. The maximum biooil production (liquid product) was achieved at 550 o C, the yield of gas product increases with increase in the reaction temperature, while residue product is inverted. On studying effluence of other parameters, the maximum bio-oil production was achieved at conditions: 0.354 mm to 0.5 mm of biomass size, 0.5ml/min of nitrogen gas flow rate and 7.5 o C/min of the heating rate. This result will be the basis for orientation of researching on the ability to produce bio-oil from biomass by pyrolysis method in next time.

Pyrolysis studies on conventional biomass were carried out in fixed bed reactor at different temperatures 300, 350, 400 and 450°C. Agricultural residues such as corn cob, wheat straw, rice straw and rice husk showed that the optimum temperatures for these residues are 450, 400, 400 and 450°C respectively. The maximum bio-oil yield in case of corn cob, wheat straw, rice straw and rice husk are 47.3, 36.7, 28.4 and 38.1wt% respectively. The effects of pyrolysis temperature and biomass type on the yield and composition of pyrolysis products were investigated. All bio-oils contents were mainly composed of oxygenated hydrocarbons. The higher area percentages of phenolic compounds were observed in the corn cob bio-oil than other bio-oils. From FT-IR and (1)H NMR spectra showed a high percentage of aliphatic functional groups for all bio-oils and distribution of products is different due to differences in the composition of agricultural biomass.
