Special Issue Information

Dear Colleagues,

Chemical systems play a fundamental role in addressing critical challenges related to sustainable development, environmental protection, and industrial innovation. Advances in catalysis, green chemical processes, and environmental monitoring are essential for the transformation of traditional industrial practices into cleaner, more efficient, and environmentally friendly systems. These advances influence a wide range of applications, including energy production, waste management, resource utilization, and pollution control.

This Special Issue on “Advances in Chemical Systems: Catalysis, Green Processes, and Environmental Monitoring” aims to collect cutting-edge research that drives innovation in these domains. Topics of interest range from the design and optimization of catalytic materials to the implementation of greener chemical methodologies and the development of advanced monitoring techniques for environmental protection. Special attention will be given to interdisciplinary approaches that integrate chemical engineering, environmental sciences, and process design to address pressing societal needs.

We encourage contributions that include experimental studies, modeling and simulation, techno-economic analyses, and life cycle assessments. Authors are invited to share supporting materials, such as data sets, modeling files, and supplementary code, through open-access repositories to foster collaboration and reproducibility.

This Special Issue provides an excellent platform to showcase your latest work and collaborate with leading researchers in the field. We look forward to receiving your valuable contributions.

In ethanol production processes, inhibitors are formed as by-products depending on the raw materials and pretreatments. Inhibitors negatively affect both ethanol yield and biomass growth. This study aimed to examine the influence of inhibitors, including acetic acid (AA), formic acid (FA), and phenol, on ethanol production from the glucose-based medium using immobilized Saccharomyces cerevisiae in a bioreactor. The results showed that the highest ethanol yields and productions were determined as 45.64% and 38.10 g/L, 44.8% and 36.67 g/L, and 44.46% and 39.07 g/L, by the addition of 2.5 g/L AA, 0.5 g/L FA, and 0.5 g/L phenol into the fermentation medium, respectively. Regarding mathematical modeling, the models MGM (AA) and Huang (FA-phenol) were the best models to predict experimental ethanol production. It was determined that the values forecasted with the models MMF (AA-FA) and Weibull (phenol) agreed with the actual biomass growth. Additionally, to forecast the observed values of the substrate consumption, the most suitable model was Weibull (AA-FA-phenol). Consequently, the immobilized-cell ethanol fermentations with inhibitors were successfully performed, and their limit values were determined. Full article
