Due to the specific characteristics of sewage sludge from food industry, including its high fat content, treatment is quite complex. Therefore, in this study, effect pre-treatment processes torrefaction (T) and hydrothermal carbonization (HTC) on pyrolysis industrial (SS) vegetable oil industry was investigated by thermogravimetric analysis. Kinetic thermodynamic analysis performed using Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), Friedman (FRI) iso-conversional kinetic models. In addition, influence water replacement whey process subsequent kinetics. The activation energy (Eα) values for ranged 49 372 kJ/mol. Pre-treatment (torrefaction, carbonization) increases significantly: Eα torrefied (T-SS) hydrothermally treated (HTC-SS) samples 177 689 kJ/mol 161 486 kJ/mol, respectively. variations generally lower energies HTC-SSW sample (158–445 kJ/mol) indicate that use HTC affects hydrochar properties kinetics significantly. According results, reflected better thermochemical stability samples, as well parameters pyrolysis, since pre-treated (especially sample, T-SS) exhibited higher entropies enthalpies Gibbs free energies.

The purpose of this manuscript is to present a review laboratory experiments (including methodology and results) that use biochar, specific carbon obtained by pyrolysis process from different feedstocks, as an alternative material for heavy metal adsorption groundwater. In recent years, many studies have been conducted regarding the application innovative materials water decontamination develop more sustainable approach remediation processes. biochar groundwater has particularly attracted interest researchers because it permits reuse would be otherwise disposed of, in accordance with circular economy, reduces generation greenhouse gases if compared virgin materials. A approaches results reported current literature could useful when applying technologies at field scale, preliminary phase which suitability adsorbent evaluated lab scale often necessary. This paper therefore organised short description involved metals production composition. comprehensive analysis knowledge related obtain characteristic parameters are necessary upscaling technology also presented. An overview achieved using experimental conditions, such chemical properties dosage well concentrations their values pH, reported. At end, numerical interpretation experiment introduced.
