On validity, physical meaning, mechanism insights and regression of adsorption kinetic models

Journal of Molecular Liquids, Год журнала: 2023, Номер 376, С. 121416 - 121416

Опубликована: Фев. 8, 2023

The study of adsorption kinetics is ubiquitous when reporting new adsorbent materials in the literature. information these tests provide are no doubt valuable, but conclusions drawn from kinetic models many times contradictory between papers. In this work, validity and meaning common reviewed literature dealing with their mathematical development, discussed. It found that most models, pseudo second order first have ability to fit data originating systems limited by surface reaction diffusion. Thus, not associated just one mechanism further precautions analyzing should be taken. Other less also discussed, as they can used gain clearer insights into rate limiting step. Another important topic discussed type regression used. Linear has a bias toward model estimated parameters very bad, which particularly true for pseudo-first model. wrong more easily chosen. benefits employing nonlinear criteria selection elaborated upon, using case studies different solutes examples.

A Review on the thermochemical conversion of sugarcane bagasse into biochar

Cleaner Materials, Год журнала: 2022, Номер 6, С. 100162 - 100162

Опубликована: Окт. 31, 2022

Sugarcane bagasse (SCB) is the fibrous lignocellulosic residue left over after crushing sugarcane to extract juice for sugar and ethanol production. In this review, a concise overview of existing thermochemical technologies production biochar from SCB its potential applications presented discussed. Some used so far in regard include pyrolysis, gasification, hydrothermal carbonization, torrefaction. However, pyrolysis was found be most widely among them. These processes can affected by several operating conditions such as temperature, heating rate, particle size, residence duration, with temperature being significant efficient variable influencing quality biochar. The yield reported literature ranged 14 % 56 %. A higher obtained at lower than one because decomposes temperatures (>500 °C). has promising agriculture environment, including soil amendment, adsorbent water wastewater treatment, supplementary cementitious material, amongst others. knowledge gaps were also stated study, cost analysis comparison utilizing fuel industries become highly carbon material wide range variety sectors.

Thermochemical co-conversion of biomass-plastic waste to biochar: a review

Green Chemical Engineering, Год журнала: 2023, Номер 5(1), С. 31 - 49

Опубликована: Март 15, 2023

Biomass and plastics are two of the most common municipal solid wastes globally that have continuously placed a burden on environment. It is therefore important they properly recycled. Thermochemical co-conversion offers valuable opportunity to recycle biomass simultaneously into biochar, which reduces time cost recycling them individually while producing material with wide range applications. This study review published literature discusses thermochemical co-processing plastic biochar. was observed co-pyrolysis co-hydrothermal carbonization commonly utilized technologies for this process. The characteristics different been thermochemically converted biochar were compared. properties resulting affected by feedstock composition, pre-treatment blending ratio, reactor's configuration, reaction temperature, presence catalyst. Most studies found treating feedstocks separately resulted in lower yield than processing together. created procedure has used as soil additive an adsorbent water treatment. Future perspectives suggestions, such necessity some technical advancement, biochar's economic benefits, improved government participation, raised social awareness, also made. These factors potential propel field great horizons.

Efficient recycling of disposable face masks via co-carbonization with waste biomass: A pathway to a cleaner environment

Cleaner Environmental Systems, Год журнала: 2022, Номер 6, С. 100094 - 100094

Опубликована: Сен. 1, 2022

Used COVID-19 masks produce a large amount of garbage that frequently overwhelms waste management facilities, hence they are disposed improperly. It is imperative to develop processing technique harnesses disposable face create biofuel in order address the environmental problems caused by their disposal. In this study, biochar production through co-carbonization mask and biomass (Daniella oliveri leaves) using fixed-bed updraft reactor was investigated as means recycling wastes for sustainable environment. A hybrid with 40.20 wt% yield produced at peak temperature 350 °C, while 32.87 only high 279 °C. According sample analysis, biochar, which has specific surface area 397.8 m2/g, very porous numerous cracks fissures. The Fourier transform infrared analysis showed presence functional groups, mainly hydroxyl carbonyl co-carbonized mask, indicating possibility an adsorbent increase soil fertility.
