Abstract: KF/Al2O3 reached maxinmun activity at the pretreatment temperature(Tp) of 623K or 723K in Ibuters isomerization at 273K. according to the amount of KF loaded. Further increment of Tp lowered the activity of KF/Al2O3 due the suppression of [Al-OHF]strong basic sites through dehydroxylation. Changes in the state and function ofF caused the deactivation of KF/Al2O3 at high Tp.

A novel in-situ spectroelectrochemical technique, the combination of probe beam deflection (PBD) with cyclic voltammetry (CV),was used to study the ion cxchange process of prussian blue(PB) modified film electrode in contact with various electrolyte solutions. The ion exchange mechanism was veritied as following: where on reduction PB film in contact with an acidic KCl electrolyte, it was confirmed that protons enter into the PB film before K+ cations.

To satisfy the requirements of accurate operationalrisk assessment of integrated transmission and distribution networks (I-T&D), an integrated operational risk assessment (IORA) algorithm is proposed. Specific cases demonstrate thatan I-ORA is necessary because it provides accurate handlingof the coupling between transmission and distribution networks,accurate analysis of power supply mode (PSM) changes ofimportant users and helps to improve security and stability ofpower grid operations. Two key technical requirements in theI-ORA algorithm are realized, i.e., integrated topology analysisand integrated power flow calculation. Under a certain contingency, integrated topology analysis is used to assess the risksof substation power cuts, network split and PSM changes ofimportant users, while the integrated power flow calculation,based on the self-adaptive Levenburg-Marquard method andNewton method, can be implemented to assess risks of heavyload/overload and voltage deviation. In addition, the graphicsprocessing unit is used to parallelly process some computationintensive steps. Numerical experiments show that the proposedI-ORA algorithm can realize accurate assessment for the entireI-T&D. In addition, the efficiency and convergence are satisfying,indicating the proposed I-ORA algorithm can significantly benefitreal practice in the coordination operation of I-T&D in the future.

A series of rare earth hydroxides and oxides ultrafine powders have been prepared by precipitation method using alcohol as dispersive and proteclive reagent. It was first to find that the crystallite size of cubic rare earth oxides had lanthanide shrinking effect, but average crystal lattice distortion rate possessed lanthanide swelling effect; the change of diffraction intensity with atomic number presented an inverted W type, and double peaks structure was formed.
