An Experimental Study of Steam Gasification of Biomass over Precalcined Copper Slag Catalysts Shuanghui Deng1,a, Jianhang Hu1,b,*, Hua Wang1,2,c, Juanqin Li1,d and Wei Hu1,e 1Engineering Research Center of Metallurgical Energy Conservation & Emission Reduction, Ministry of Education, Faculty of Metallurgical and Energy Engineering, Kunming University of Science and Technology, Kunming, 650093,China; 2State Key Lab.
During gasification process, the biomass material is heated to a high temperature, which causes a series of physical and chemical reactions that result in a mixture of hydrogen, carbon oxides, small amounts of methane and higher hydrocarbons.
The levels of biomass gasification are associated with characteristics of material, gasification temperature, reactor type, heating rate and gasifying agent [1-3].

Research on Thermocouple Embedded Position for CC mould Copper Plate with High Casting Speed Sun Ligen1, a Zhang Jiaquan2,b 1School of Metallurgical and Energy, HEUU, Tangshan 063009,china 2 School of Metallurgical and Ecological Engineering, USTB, Beijing 100083, China asunligen@heuu.edu.cn, bjqzhang@ustb.edu.cn Keywords: mould plate; thermocouple; high casting speed; breakout prevention Abstract: High casting speed would increase the occurrence probability of sticking, and make it harder for breakout signals catching.
Introduction Casting speed is one of the key technical parameters for continuous casting.
The major assumptions are as follows: 1) Casting speed and Casting temperature are constant value; 2) Casting speed with neglected thermal conduction in casting direction; 3) Small deformation of the mould plates and steel shell with only material nonlinearity; 4) The influence of the thermal convection of the molten steel at the solidifying front is described by equivalent thermal conductivities according to the local temperature; 5) Thermo-elastic-plastic model is adopted for the steel shell, and the thermo-elastic model is used for the copper plates.
