The synthesis parameters, such as the reaction temperature, the first aging temperature and the second aging temperature, were investigated. The textural properties of γ-Al2O3 were characterized by means of N2 adsorption-desorption isotherms, X-ray powder diffractometry （XRD）, scanning electron microscopy （SEM）, Fourier transform infrared （FTIR） spectroscopy and thermogravimetry （TG）. The experimental results indicated that AACH and amorphous A1OOH were the precursors of alumina, which were formed via precipitation from solutions after reaction of aluminum sulphate with ammonium hydrogen carbonate. The precursor nanocrystallites grew and re-assembled during the secondary reforming process, which resulted in an increased pore size and pore volume and a decreased bulk density. The as-synthesized γ-Al2O3 materials featured meso/macroporosity, large pore volume （2.175 cm^3/g）, high surface area （237.8 m^2/g）, and low bulk density （0.284 g/mL）.展开更多

The effects of the sol-gel method on the specific surface area, catalytic activity, desorption, and reduction performances of catalysts were investigated with BET, TPR, and TPD. Compared with the catalyst prepared by the impregnation method, the results indicated that the catalysts prepared by the sol-gel method had larger specific surface area, showing higher catalytic activities and exhibiting perfect desorption and reduction performances. In addition, the modification effects of adding La were studied, and it was found that the 0.75NLBT catalyst constituted of 5wt.%Ni-0.75wt.%La was optimal.展开更多

In order to meet the needs of social development, the plans and policies of proofreading talent training in Colleges and universities are also constantly being reformed and adjusted. In order to ensure the advanced nature and the times of the education, institutions and teachers constantly update the educational content, teaching material compilation standards and teaching system. The purpose is to ensure that the knowledge and technology that the talents learn in the process of training talents are in line with the development of the society, and can meet the requirements and standards of the society for talents. Even so, there are still few talents who can really meet the social development, which is mainly related to the talent training mode of colleges and universities.展开更多

The equilibrium calculations employing the Gibbs energy minimization were performed upon wide ranges of pressure （1-25 atm）, temperature （600-1300 K）, carbon dioxide to methane ratio （0-2） and oxygen to methane ratio （0-1）. The thermodynamic results were compared with the results obtained over a Ru supported catalyst. The results revealed that by increasing the reaction pressure methane conversion decreased. Also it was found that the atmospheric pressure is the preferable pressure for both dry reforming and partial oxidation of methane and increasing the temperature caused increases in both activity of carbon and conversion of methane. The results clearly showed that the addition of O2 to the feed mixture could lead to a reduction of carbon deposition.展开更多

This change in the logic of factual judgments has caused a change in the methods of evidence examination. In traditional evidence examination, evidence obtained from investigations is supposed to be genuine and reliable. In the substantive reform of court trials, it is presumed that evidence obtained from investigations cannot be fully trusted and it is easier to ascertain the facts of the case by investigating using the principles of directness, verbalism and individualized judging methods for evidence examinations. In practice, there are three main factors affecting the genuineness of evidence: the cognitive rules of testifiers, the motivation of the subjects who provide evidence, and the methods used by investigators to obtain evidence. Based on any one of these three factors, it cannot be concluded that evidence obtained from investigations is superior to evidence presented in court. The substantive court investigation is more advantageous to establishing the facts of a case than the traditional court investigation. The essential characteristics of the substantive reform of court trials are pursuing reality in essence instead of in form, and using the files of the court trials instead of the files of the investigation to avoid the evidence obtained through investigations from playing a decisive role in the adjudication thus making criminal procedures trial-centered rather than investigation-centered.展开更多
