“…The estimated values of activation energies from different models at multiple heating rates of 5, 10 and 20°C/min are in close agreement with each other and agree with the reported literature. ( Farooq et al, 2021 ). estimated activation energy for the pyrolytic conversion of Parachlorella kessleri HY-6 using KAS and Friedman methods as 241.91 (±53.05) kJ/mol and 253.54 (±58.81) kJ/mol, respectively.…”

This study investigates CO2 biofixation and pyrolytic kinetics of microalga G. pectorale using model-fitting and model-free methods. Microalga was grown in two different media. The highest rate of CO2 fixation (0.130 g/L/day) was observed at a CO2 concentration of 2%. The pyrokinetics of the biomass was performed by a thermogravimetric analyzer (TGA). Thermogravimetric (TG) and derivative thermogravimetric (DTG) curves at 5, 10 and 20°C/min indicated the presence of multiple peaks in the active pyrolysis zones. The activation energy was calculated by different model-free methods such as Friedman, Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), and Popescu. The obtained activation energy which are 61.7–287 kJ/mol using Friedman, 40.6–262 kJ/mol using FWO, 35–262 kJ/mol using KAS, and 66.4–255 kJ/mol using Popescu showed good agreement with the experimental values with higher than 0.96 determination coefficient (R2). Moreover, it was found that the most probable reaction mechanism for G. pectorale pyrolysis was a third-order function. Furthermore, the multilayer perceptron-based artificial neural network (MLP-ANN) regression model of the 4-10-1 architecture demonstrated excellent agreement with the experimental values of the thermal decomposition of the G. pectoral. Therefore, the study suggests that the MLP-ANN regression model could be utilized to predict thermogravimetric parameters.

“…Fast pyrolysis and upgrading of crude bio-oil can be carried out with or without the catalyst. Several kinds of catalysts used for the bio-oil upgradation (N i , zeolite, Al 2 O 3 , P d , P t , TiO 2 , etc) (Mortensen et al, 2011;Miandad et al, 2019;Farooq et al, 2021). The catalytic bio-oil has less acidic and oxygen compounds than non-catalytic bio-oils.…”

Biomass pyrolysis is one of the beneficial sources of the production of sustainable bio-oil. Currently, marketable bio-oil plants are scarce because of the complex operations and lower profits. Therefore, it is necessary to comprehend the relationship between technological parameters and economic practicality. This review outlines the technical and economical routine to produce bio-oils from various biomass by fast pyrolysis. Explicit pointers were compared, such as production cost, capacity, and biomass type for bio-oil production. The bio-oil production cost is crucial for evaluating the market compatibility with other biofuels available. Different pretreatments, upgrades and recycling processes influenced production costs. Using an energy integration strategy, it is possible to produce bio-oil from biomass pyrolysis. The findings of this study might lead to bio-oil industry-related research aimed at commercializing the product.

“…Farooq et al investigated the efficacy of a prepared Ni/θ-Al 2 O 3 catalyst during the pyrolytic conversion of microalgae and compared the results with non-catalytic conversion. The presence of the catalyst facilitated the pyrolysis and the gases that evolved during pyrolysis were qualitatively analyzed to see the effect of the catalyst on evolved gas composition during the pyrolysis process [ 80 ].…”

On-Line Thermally Induced Evolved Gas Analysis: An Update—Part 1: EGA-MS

Advances in on-line thermally induced evolved gas analysis (OLTI-EGA) have been systematically reported by our group to update their applications in several different fields and to provide useful starting references. The importance of an accurate interpretation of the thermally-induced reaction mechanism which involves the formation of gaseous species is necessary to obtain the characterization of the evolved products. In this review, applications of Evolved Gas Analysis (EGA) performed by on-line coupling heating devices to mass spectrometry (EGA-MS), are reported. Reported references clearly demonstrate that the characterization of the nature of volatile products released by a substance subjected to a controlled temperature program allows us to prove a supposed reaction or composition, either under isothermal or under heating conditions. Selected 2019, 2020, and 2021 references are collected and briefly described in this review.
