Effects of impregnated potassium on biomass torrefaction

Sensitivity analysis: A tool for tailoring environmentally friendly materials

“…Although some studies, e.g. (Lubura et al, 2021), (Safar et al, 2019), (Vodka & Pogrebnyak et al, 2020) and (Lopes, Silva, & Machado, 2021), have used ANN networks for the prediction of different processes in rubber technology, they focused on the prediction of different parameters but none of them take into account the environmental aspect of rubber technology. As the production of rubber compounds also has its environmental impact, it is necessary to focus on the optimization of chemical compounds.…”

Torrefaction of Wood in a Quiescent Layer of Talc

“…For example, the use of potassium salts can enhance the thermal decomposition of biomass and can affect the composition of the gaseous products of pyrolysis. 17,18 The resultant properties of biofuels depend strongly on wood species, 19,20 torrefaction temperature, holding time, and pressure inside the reactor. 21 Torrefaction of biomass improves the grindability of raw biomass by the transformation from a fibrous structure to a more brittle, coal-like material.…”

“…At the same time, reduction in cost could potentially be achieved if torrefaction is carried out in an oxidative atmosphere (“the oxidative torrefaction”) because of the utilization of air and exothermic reactions proceeding in an oxidizing environment. , Furthermore, the thermal processing of the biomass can be carried out in media such as carbon dioxide and water. − An important direction in contemporary research is the analysis of the possibility to utilize catalysts and mineral fillers in the process of biomass torrefaction. For example, the use of potassium salts can enhance the thermal decomposition of biomass and can affect the composition of the gaseous products of pyrolysis. , …”
