Abstract：Based on the task and objective of 2013 plan， the research works of this project was carried out by the researchers from commitment unit and all the works were organized and coordinated carefully. All the research woks of 2013 pan were finished and the objective were obtained. Based on reduced order model， the temperature distribution， the slag thickness on the membrane wall in the slurry feed membrane wall gasifier was calculated and the computational complexity was reduced too. A dynamic simulation model of the gasification island was built and the simulation results were verified by the commercial operation data. A zonal mode with fast calculation speed of opposed multi-burner gasifier was built， the model result was well agree with commercial operation data. The migration property of chloride in the coal during gasification process was obtained based on the experiment and thermodynamics analysis of the chloride in the coal， coal ash， coarse and fine ash after gasification process and the waste water. Two simulation models for hydrogen production using petroleum as feedstock were built using Aspen Plus， based on the analysis and evaluation of these two process， the thermal efficiency and exergy efficiency of energy conversion was calculated.

Key Words：Reduced order model；Simulator；Zonalmodel；Energy conversion
