Preface
Since 1990, China has carried out research on benzene selective hydrogenation catalyst and related basic theories and applications, and has resolved the key technology problems for benzene selective hydrogenation to cyclohexene in China. After 2010, China became the second country in the world to realize the industrialization of the catalytic technology for benzene selective hydrogenation to cyclohexene and held the proprietary intellectual property rights.
This book introduces the catalytic technologies of benzene selective hydrogenation to cyclohexene and its downstream products, the developing history and present status, and the innovative work conducted in China. Selective hydrogenation of benzene to cyclohexene is a complex heterogeneous catalytic system. It involves catalyst, catalytic process, key equipment, and a complete set of production facilities from laboratory to industrialization. Summarizing the research work systematically in the field of study and exploring the heterogeneous catalytic mechanism and the scientific essence of high yield and selectivity of cyclohexene are not only academically valuable, but also can promote technical progress of this research area.
This book reveals the objective laws, reaction mechanism, and scientific essence based on the experimental data, analysis, and characterization results and references, which will guide industrial production. The improved catalyst can enhance the selectivity and yield of cyclohexene with low resource consumption and environmental pollution. It is also valuable for peer specialists and technical workers.
The authors division for this book is as follows: Liu Zhongyi is the Editor-in-Chief for Chaps.. Liu Zhongyi and Liu Shouchang are also responsible for the ordination and review of the whole book.
This book is supported by the fund from the Ministry of Science and Technology and the National Natural Science Foundation. We also acknowledge the contribution of graduate students, enterprises, and related technical workers.

Brief Introduction
Selective hydrogenation of benzene to prepare cyclohexene and its downstream products such as cyclohexanone, adipic acid, caprolactam, nylon 6, nylon 66, and bulk chemicals and high-value fine chemicals such as medicine, pesticides, essence, and spices are resource saving and environment friendly, and play an important role in national economic development. The main contents of this book involve the thermodynamics of benzene selective hydrogenation, heterogeneous catalytic kinetics, catalytic mechanism and scientific essence, catalyst of benzene selective hydrogenation, modulation on activity and selectivity of the catalyst, studies on deactivation and regeneration of the catalyst as well as the catalytic process, key equipment, and complete set of production facilities.
This book gives a lot of experimental data, analysis, and characterization maps and important references. It can provide the reference for the related professionals of advanced college and scientific research institutes, senior undergraduate, masters and doctoral graduate students as well as for the personnel of related enterprises where they engage in management or industrial production.

Selective hydrogenation of benzene from the fossil and coal companies into cyclohexene and its downstream products including bulk chemicals of cyclohexanone, adipic acid, hexanolactam, nylon 6, nylon 66, and high value fine chemicals of medicine, pesticide, and perfumes are of great significance for the economic development. Compared with the traditional process of benzene, hydrogenation into cyclohexane is safe, resource saving, environmentally friendly, and has giant economic and social benefits for the selective hydrogenation of benzene into cyclohexene.
It has been a dream for a long time in history that selective hydrogenation of benzene into cyclohexene was considered very hard, especially in the field of industry. Many countries such as America, England, German, and Japan conducted universal researches from 1960 to 1990s. And Japan firstly realized the industrialization in 1989, and transfer the technology to China, in 1995 and 2005, respectively. However, they monopolized the catalysts preparation method.
