The Chemical Engineering Journal focuses upon five aspects of chemical engineering: catalysis, chemical reaction engineering, environmental chemical engineering, green and sustainable science and engineering, and novel materials. The Chemical Engineering Journal is an international research journal and invites contributions of original and novel fundamental research. The journal aims to provide an international forum for the presentation of original fundamental research, interpretative reviews and discussion of new developments in chemical engineering. Papers which describe novel theory and its application to practice are welcome, as are those which illustrate the transfer of techniques from other disciplines. Reports of carefully executed experimental work, which is soundly interpreted are also welcome. The overall focus is on original and rigorous research results that have generic significance. Within the Chemical Engineering Journal, the Catalysis section presents Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis with industrial impact on chemicals, energy, materials, foods, healthcare, and environmental protection
