This book focuses on e-commerce industry chain based on the whole process of e-commerce activities (production, distribution, circulation, consumption). It extracted the supporting technology and operation process of e-commerce into general principles in the form of mathematical analysis, helping readers to build the frame of theory and practice of activity link of e-commerce. This book stands on the concepts, carries on the innovation and cases in the practice, helping readers to establish a relatively complete e-commerce system. Also the arising challenges and issues are discussed, and guide for the future e-commerce development under the new situation is presented.

This book provides a comprehensive description of the catalytic technologies for selective hydrogenation of benzene to cyclohexene. Focusing on selective hydrogenation of benzene to prepare cyclohexene and its downstream products, such as cyclohexanone, bulk chemicals and high-value fine chemicals, it also discusses the objective laws, reaction mechanisms and scientific significance based on experimental data, analysis and characterization results. Given its scope, the book will appeal to a broad readership, particularly professionals at universities and scientific research institutes, senior undergraduates, master's and doctoral graduate students as well as practitioners in industry.
