Textbook in PDF format We are glad to present to your attention a new journal, "Engineering Chemistry". The first volume contains articles on three topical directions: biofuel production, hydrometallurgy and environmental protection. Membrane microfiltration of glycerol from biodiesel, analysis of challenges in syngas fermentation for bioethanol production, a method for controlling the purity of produced dimethyl ether, investigation of extraction technology for manganese sulfate solution purification in hydrometallurgical production and the review of progress on the use of carbonaceous catalysts activated persulfate for degradation of antibiotic pollutants in wastewater are the topics of articles collected here. This volume will be helpful to specialists in chemical production. Microfiltration Performance of α-Alumina Membrane for Removal of Glycerol from Biodiesel Challenges in Syngas Fermentation for Bioethanol Production: Syngas Composition Enhance the Growth of Clostridium ljungdahlii Microbial Cells by Modifying the Medium Composition and Trace Metals Determination of Data Driven Soft Sensors in Dimethyl Ether Production by Reactive Distillation Column Peak Wavelength Mapping of Triangular Reflection in Spherical Colloidal Cluster with Icosahedral Symmetry Extraction Technology for Manganese Sulfate Solution Purification Carbonaceous Catalyst Activated Persulfate for Degradation of Antibiotic Pollutants in Water
