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].

Pollution and Control Measures of Livestock Breeding with Acceleration of China’s Urbanization Zaifu YANG1,a　　　 Lianlian XU1 Chuenyun YAO2,b 1School of Environmental Science and Engineering, Donghua University, Shanghai 201620, P.R.China 2Songjiang Environmental Protection Bureau.
They are the key towns of the pollution from scale raising and breeding farm.
At the same time, there are not clearly laws about the harmful material in the animal feed remaining in livestock body and polluting the environment.
We should cultivate improved breeds, use “ideal protein model” animal feeds, adopt technology of nutritional equilibrium prescription (such as enzyme preparation of genetic engineering, auxin, mineral supplement),and apply feed enzyme preparation and microecological preparation in order to increase utilization rate of protein, calcium, phosphorus, copper, zinc and trace element, restrain propagation of putrefying bacteria, reduce the amount of endotoxin and urea enzymes and reduce the production of harmful gas [6-11].
The breeding farm must be built far away from city, the living area, densely populated areas, rivers and underground water source, adopt the method of systematic engineering, project, organize and adjust the proportion of agriculture, forestry, stock raising and fish and the industry structure positioning on local conditions, promote material circulate and cyclic utilization in system.

When designing an absorption process, two key parameters must be taken account, namely, capture-ratio (CR) and heat-ratio (HR).
The base material for the construction of the pipes is carbon steel with 20” diameter.
This indicator enables the economic analysis and also admits the costs involved in the purchase of raw material, (CRM), cost of utilities (CUT) and costs of labor (COL) [10].
These parameters are related to providing the cost of manufacturing (COM) of the enterprise according to Eq. 5: . (5) Sugarcane is the only raw material used, purchased a price of 22.29 USD/t [11].
