Open Journal of Chemical Engineering is an international, peer-reviewed, open-access journal dedicated to publishing high-quality original research and innovative studies in chemical engineering. The journal provides a global platform for researchers, engineers, and practitioners to present fundamental research, applied studies, interpretative reviews, and discussion of emerging technologies in chemical engineering. Manuscripts describing novel theories, their practical applications, or the adaptation of techniques from other disciplines are particularly encouraged. The journal also welcomes rigorously conducted experimental work with sound analysis and interpretation. Research topics include chemical reaction engineering, process systems engineering, process intensification, materials science and engineering, separation processes, catalysis, environmental chemical engineering, biochemical engineering, polymer and materials processing, energy and sustainability in chemical processes, process simulation and modeling, and industrial applications. The journal aims to promote interdisciplinary approaches and innovation that contribute to the advancement of chemical engineering knowledge globally.
