EXPERIMENTAL PROGRAM 2.1 Instrumentation X-ray diffraction (XRD) model PW1877, Infra-red spectrophotometer (FT.IR) model 8300, Thermo gravimetric Analyzer (TGA), Melting point measurement model M.F B 600-010 F as well as other normal laboratory equipment and glassware were used. 2.2 Materials The phenolic resin (novalac) prepared in the laboratory, was used as a source of carbon for graphitization process.
Beyond these regions, the pyrolysis of the materials continued with slower rate and lose in weight are stopped, which tends to saturate in temperature range between 625-1000oC for the resins BMR and NMR, being in the temperature more than 1000oC for resin (NR).
Beyond these temperature, the pyrolysis and the weight loss of the materials continued slowly.

Factors Affecting the Performance of Molten Salt Heat Receiver Peijuan Li1, a, Yuting Cheng1,b and Shi Liu2,c 1School of Power, Energy and Mechanical Engineering, North China Electric Power University, Beijing 102206,China 2 School of Control & Computer Engineering, North China Electric Power University, Beijing 102206,China alipeijuan1234@sina.com, bcytko@126.com, cliushi_ncepu@yahoo.com.cn Keywords: Tower solar power; Numerical simulation; Molten salt receiver Abstract.
Because salt itself is very good melting regenerative materials, so that the heat transfer and heat storage of the solar heating system can be shared by the same medium, make the system greatly simplified[1-5].
