Low-Temperature Isomerization of 1-Butene on Mo₂N/γ-Al₂O₃ Catalyst Studied by in Situ FT-IR Spectroscopy

The Journal of Physical Chemistry B (2001)

Zili Wu Can Li Pinliang Ying Zhaobin Wei Qin Xin

The adsorption and reaction of 1-butene on Mo2N/γ-Al2O3 catalyst have been studied by in situ FT-IR spectroscopy at low temperatures, 145 K to room temperature (RT). The adsorbed 1-butene can be converted to cis- and trans-2-butenes below 201 K on Mo2N/γ-Al2O3 catalyst. The result of coadsorption of 1-butene with CO indicates that 1-butene is mainly adsorbed on the surface Mo sites of the nitrided catalyst. No isomerization of adsorbed 1-butene and 2-butenes on reduced passivated Mo2N/γ-Al2O3 sample below RT is observed. It is suggested that the double-bond migration (DBM) of 1-butene is mainly proceeded via an alkyl species on the surface cus Mo sites of Mo2N/γ-Al2O3 catalyst. This resembles the behaviors of Group VIII metals in the isomerization of butenes. The incorporated nitrogen atoms are proposed to devote to both the valence state of surface Mo sites and the interaction between 1-butene and the nitrided catalyst. A possible path from 1-butene conversion to 2-butenes on Mo2N/γ-Al2O3 catalyst is proposed.

Advance Selling Decision for Perishable Products in the Presence of Strategic Consumers

2021 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM) (2020)

Yanli Fang Zhuoyi Ren Zhaobin Wei

The advance selling strategy is often used in the sales process of perishable products with a short life cycle. The advance sales can encourage more strategic consumers to buy the product in advance with a discount price due to the extended sales period, but may also bring more profits for the seller. The seller often faces a newsvendor problem, i.e., they must order the joint decisions about an advance-selling price and inventory with uncertain demand in a two-period season, where the first period is the advance selling period and the second is the spot selling (and consumption) period. This paper establishes a two-period theoretical model to discuss the interaction between the advance selling decisions and consumers' strategic purchasing behaviors. The game model show how the seller should optimally respond to consumers' strategic behavior and characterize a cost threshold above which they should whether to advance sell. Finally, it is found that the advance selling strategy is not always optimal, but is related to the parameters of the cost per unit, the consumers' valuations and heterogeneity.

Quality Control Risks of Construction Agent Project on Carrying Out

Journal of North China Institute of Science and Technology (2008)

Zhaobin Wei

Construction agent organization will meet various risks during implementation of construction agent project,especially the construction agent of the Olympic rebuilding project,because of the aging establishment,referring many specialties and having quality hidden trouble,as makes the construction agent more difficult and the risk bigger.It is systematic analyzed quality control risks of construction agent project on carrying out,discussed and summarized that response measurement of risk precaution,according to the experience of taking part in many construction agent projects,combining with practical case and characteristic of rebuilding project.it is of important practical values to accumulate experience for more successfully carrying out construction agent project and perfect the management theory of construction agent project.
