Strategic Study of CAE 2012, Volume 14, Issue 7,   Pages 24-33

Abstract:

From the characteristics of military engineering construction which are different from civil engineering construction, this paper brings forth the background of the harmonious management of military engineering construction. Based on organizational behavior, military engineering economics, system coevolution, and from the point of ontology, epistemology and methodology, this paper describes the logical relationship and system framework of the “persons events things”, and operation mechanism of the harmonious management of military engineering construction, then builds up the theoretical framework of the harmonious management of military engineering construction. From the point of the Renli harmony of “leaders employees group” subject factors, Wuli harmony of “quality construction period cost” object factors, Shili harmony of “knowledge tool method” relationship factors, system environment harmony of “military technology economy”, this paper discusses the realization mode of the harmonious management of military engineering construction, then sets up the evaluation model of the harmonious management mode of military engineering construction.

Enhancing the aromatic selectivity of cyclohexane aromatization by CO2 coupling

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 11,   Pages 1801-1808 doi: 10.1007/s11705-023-2325-9

Abstract: Improving the aromatic selectivity in the alkane aromatization process is of great importance for its practical utilization but challenge to make because the high H/C ratio of alkanes would lead to a serious hydrogen transfer process and a large amount of light alkanes. Herein, CO2 is introduced into the cyclohexane conversion process on the HZSM-5 zeolite, which can improve the aromatic selectivity. By optimizing the reaction conditions, an improved aromatic (benzene, toluene, xylene, and C9+) selectivity of 48.2% can be obtained at the conditions of 2.7 MPa (CO2), 450 °C, and 1.7 h−1, which is better than that without CO2 (aromatic selectivity = 43.2%). In situ transmission Fourier transform infrared spectroscopy spectra illustrate that many oxygenated chemical intermediates (e.g., carboxylic acid, anhydride, unsaturated aldehydes/ketones or ketene) would be formed during the cyclohexane conversion process in the presence of CO2. 13C isotope labeling experimental results demonstrate that CO2 can enter into the aromatics through the formation of oxygenated chemical intermediates and thereby improve the aromatic selectivity. This study may open a green, economic, and promising way to improve the aromatic selectivity for alkane aromatization process.

Modeling of specific structure crystallization coupling with dissolution

Yuanhui JI, Hongliang QIAN, Chang LIU, Xiaohua LU, Xin FENG, Xiaoyan JI,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 1,   Pages 52-56 doi: 10.1007/s11705-009-0301-7

Abstract: In this paper, the research framework for specific structure crystallization modeling has been proposed in which four steps are required in order to investigate the rigorous crystallization modeling by thermodynamics. The first is the activity coefficient model of the solution, the second is Solid-Liquid equilibrium, the third and fourth are the dissolution and crystallization kinetics modeling, respectively. Our investigations show that the mechanisms of complex structure formation and microphase transition can be analyzed by combining the dissolution and crystallization kinetics modeling. Moreover, the formation mechanism of the porous KCl has been analyzed, which may provide a reference for the porous structure formation in the advanced material synthesis.
