The data obtained from the thermogravimetric analysis served as a basis for kinetic analysis with three different isoconversional, model-free methods, which were the KAS, FWO and Friedman methods. Afterwards, the activation energy and the pre-exponential factor were determined, and no significant difference could be identified among the used methods (difference was under 5%), achieving 203–270 kJ/mol of Ea on average. Thereafter, the thermodynamic parameters were studied. Based on the TG-FTIR data, a logistic regression model was fitted to the data, which gives information about the thermal degradation and the obtained components with different heating rates. The FTIR analysis resulted in differential peaks corresponding to the studied components that were detected within the temperature range of 350–380 °C. The primary degradation processes occurred within a broader temperature range of 200–600 °C. Accordingly, in this work, the use of logistic mixture models as an alternative to traditional kinetic models for the description of the TGA process was also investigated, reaching adequate performance in fitting by a validation data coefficient of determination of R2 = 0.9988.}, year = {2024}, eissn = {1996-1073}, pages = {1875}, orcid-numbers = {Zsinka, Viktória/0000-0002-5548-1118;

Ennek egyik megoldása lehet a szennyvíziszapok magas hőmérsékletű termikus átalakítása. Ennek során hidrogénben és szénhidrogénekben gazdag gáztermékek, bio-olaj és bio-char keletkezhet.

The long-term sustainable treatment and disposal of sewage sludge from residential and other sources is one of the actual challenges nowadays. However, due to the impurities caused by drug and hormone residues found in agricultural and residential wastewater occurs further problems regarding their long term environmentally sustainable disposal. One of the possible utilizations of sewage sludge is the high-temperature thermal conversion. During this process, gases rich in hydrogen and hydrocarbons, bio-oil and bio-char can be obtained. The processes taking place, the composition and quantity of the products depend on the raw materials and operational parameters in large extent. Pyrolysis is mostly investigated within the thermal processes, but there are also references to torrefaction taking place at lower temperatures. The viability and industrial implementation of the process is also fundamentally influenced by the amount of harmful components. In this work, the pyrolysis of sewage sludge from agricultural sources combined with torrefaction was investigated using TG-FTIR method and laboratory scale reactor. Mainly, the reaction kinetic parameters, the product yields and their composition was followed as function of the reaction parameters. The thermal decomposition of the raw material took place in several steps, which was significantly influenced by the temperature and reaction time of torrefaction.

Summary Due to the continuous development, the increase in population and living standards, and increase in urbanization, the amount of sewage sludge is increasing significantly. Based on dry matter, 45 million tons of domestic sewage sludge are generated annually, on the other hand, a significant part of which does not undergo further processing. Although a limited portion should be used for agriculture, because there are several problems with this. For these reasons, the use of sewage s ludge as an energy source is widely investigated. There are several options for thermochemical application. The most significant of which are carbonization (torrefaction), pyrolysis (400-700°C) and gasification (700-1000°C). Gas, liquid and solid products should be obtained by these processes. The product yields and quality depend significantly on the operational parameters to be used during the process, the composition of the raw materials and the use of catalysts. In this work, the thermal and thermo-catalytic pyrolysis of sewage sludge from agricultural sources was investigated at several different temperatures and in the presence of catalysts in a laboratory scale reactor. The product composition was followed by gas chromatography. Based on results, correlations between the process parameters and the product characteristics were concluded.}, year = {2023}, pages = {20}, orcid-numbers = {Miskolczi, Norbert/0000-0003-4862-0148} }
