Characterization of Pyrolysis Products and Kinetic Analysis of Waste Jute Stick Biomass

Abstract

Thermochemical process of biomass is being considered as a latest technique for the restoration of energy source and biochemical products. In this study, the influence of the different heating rates on pyrolysis behaviors and kinetic of jute stick were investigated to justify the waste jute stick biomass as a potential source of bioenergy. Pyrolysis experiments were carried out at four several heating rates of 10, 20, 30 and 40 °C/min, by utilizing the thermogravimetric analyzer (TG-DTA) and a fixed-bed pyrolysis reactor. Two different kinetic methods, Kissinger–Akahira–Sunose (KAS) and Ozawa–Flynn–Wall (OFW) were used to determine the distinct kinetic parameters. The experimental results showed that, the heating rates influenced significantly on the position of TG curve and maximum Tm peaks and highest decomposition rate of the jute stick biomass. Both the highest point of TG and the lowest point of Derivative thermogravimetry (DTG) curves were shifted towards the maximum temperature. However, the heating rates also influenced the products of pyrolysis yield, including bio-char, bio-oil and the non-condensable gases. The average values of activation energy were found to be 139.21 and 135.99 kJ/mol based on FWO and KAS models, respectively.

Water‐based Formuation of Inkjet Inks Using Jute Stick‐derived Submicron Carbon Particles

“…JP exhibited a low yield of ∼26%, whereas JC and BJC showed a high yield of ∼60% at 800 °C. These high yield percentages of JC and BJC confirm the formation of biochar/carbon during the mild heat treatment of jute sticks in the customized pilot furnace [44] . The stable nature of the TGA profiles between 500 °C and 800 °C and weight loss between about 350 °C to about 500 °C due to the above‐described reasons confirm the formation of biochar/carbon materials [44] .…”

High-Grade Chemicals and Biofuels Produced from Marginal Lands Using an Integrated Approach of Alcoholic Fermentation and Pyrolysis of Sweet Sorghum Biomass Residues

“…Fast pyrolysis is a thermo-chemical conversion method used to produce mainly liquid fuel from biomass, based on thermal decomposition of organic compounds in the absence of oxygen [25,26]. Pyrolysis oils are compounds that are preferred as biofuels for their high calorific values, easy transportation and storage, low nitrogen and sulfur content, and the possibility of easy conversion into high-rated chemicals [27]. Efforts to turn renewable crop biomass into fundamental chemical elements that will be integrated into various common goods have been also intensified in recent years.…”

Fast Pyrolysis as a Valorization Mechanism for Banana Rachis and Low‐Density Polyethylene Waste

“…Additionally, a study of co-pyrolysis of biomass and plastic waste identified in the gas phase alkanes with a maximum of four carbons and two additional compounds, i.e., CO and CO 2 that were obtained as result of the pyrolysis of biomass [48]. In the case of the pyrolysis of residual biomass, studies revealed that the most relevant components of pyrolytic volatiles are H 2 O, CO 2 , CO, H 2 , and CH 4 [49,50].…”
