With Fumi-Tosi interaction potential, the thermodynamic properties and the structure of alkali halide melts have been calculated using Monte Carlo computer simulation. The ratial distribution function ,ionic coordination number and the local structure were computed for several systems. The obtained equilibrium properties are in good agreement with the experimental results.

Promoter MgO on 10% CeO2/Al2O3 oxygen carrier was investigated for direct partial oxidation of methane to syngas in molten salt. The MgO content of 0.5%, 1%, 2%, 3% and 4% on the 10%CeO2/Al2O3 oxygen carriers in experiments were prepared at the temperature of 750℃, respectively. The methane conversion, H2 and CO selectivity was measured on these prepared oxygen carriers at different reaction temperature. The results showed that the 3% MgO on 10%CeO2/Al2O3 had the best activity, and the CH4 conversion and CO selectivity reached 92.58% and 87.64% at 875℃, respectively. The effect of different calcination temperature on 3% MgO as promoter on 10% CeO2/Al2O3 oxygen carrier was investigated. The results of BET indicated that oxygen carrier had the largest surface area at 750℃. When the calcined temperature was too high there would be a negative effect on oxygen carrier activity.

A computer prediction for the regularities of formation of binary bromide system was made. The results indicate that CsBr-CaBf2 molten salt system is binary complex compound-forming system. The phase diagram of CSBr-CaBt2 system has been determined by visual polythermal method in order to prove the prediction. The phase diagrams of the quasibinary system KCl-CsBr, KCl-CaBr2 and the quasiternary system CsBr-CaBr2-KCl were determined by using visual polythermal method. The phase diagrams of CsBr-CaBr2 and KCl-CaBr2 show that the intermediate compound is formed. The results are in agreement with the computer prediction. Here, the various parts of the phase diagram of the quasiternary system CsBr-CaBr2-KCl were discussed.
