A taxonomy of built asset information coupling

Frontiers of Engineering Management 2024, Volume 11, Issue 2,   Pages 247-268 doi: 10.1007/s42524-024-0311-7

Abstract: The digital transformation of the built asset industry is moving toward closer integration of physical and digital assets and resources. Within the framework of Cyber-Physical Systems (CPSs) and Digital Twins (DTs), an increasing number of studies focus on the technical aspects of CPS and DT. However, a unified framework describing the dimensions and characteristics essential for integrating lifecycle information remains elusive. To leverage these concepts effectively, it is necessary to develop new frameworks to classify and put into relationship various components that comprise the lifecycle information integration of physical and digital assets and resources. This paper addresses these gaps by proposing a taxonomy of Built Asset Lifecycle Information Couples, which outlines the dimensions and characteristics crucial for the lifecycle information integration of built assets and resources. The proposed taxonomy contributes to the efforts aimed at organizing the knowledge domain of lifecycle information management in the built environment.

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.
