Production of Biodiesel in Supercritical Methanol and Related Correlation on Phase Equilibrium Dan Zeng1,a, Yang Li2,b, Tao Fang*3,c, 1,2,3 Department of Chemistry Engineering, Xi’an Jiaotong University, Xi’an 710049, China aemail: zengdan@stu.xjtu.edu.cn,bemail: xjtu2010.liyang@stu.xjtu.edu.cn, *cemail: taofang@mail.xjtu.edu.cn Key words: Supercritical methanol, Methyl esterification,Biodiesel,Phase equilibrium Abstract.
At present, the homogeneous base-catalyzed method is widely applied by using refined rapeseed oil and soybean oil as the raw materials.
The supercritical method employed in this work is an approach producing biodiesel under the supercritical methanol condition, whose advantages are adaptability, simple pretreatment of raw materials, high yield and easy product separation [5].
Experiment Experimental materials.
In addition, all experiments were carried out in the form of batch operations and the total amount of materials inside the reactor was always fixed to be 6 ml.

Recrystallization-Texture Theories in Light of Strain-Energy-ReleaseMaximization Dong Nyung Lee Department of Materials Science and Engineering, Seoul National University Seoul 151-744, Korea and Graduate Institute of Ferrous Technology, Pohang University of Science and Technology Pohang 790-784, Korea dnlee@snu.ac.kr or dnlee@postech.ac.kr Keywords: Texture, recrystallization, oriented nucleation, oriented growth, strain-energy-releasemaximization.
The oriented-nucleation and oriented-growth for recrystallization (Rex) textures of electrodeposits, vapor deposits, and plastically deformed metallic materials have been discussed based on the strain-energy-release-maximization (SERM) model.
For polycrystalline materials, the Rex orientation predicted by the SERM model is likely to be measured because heterogeneous nucleation can occur in grain boundaries even when shear bands are absent.

Identification of environmental risks of enterprises processing and utilizing the imported scrap metals The enterprises processing and utilizing imported scrap metals face environmental risks mainly in the storage of raw materials and products, their transportation, processing and utilizing as well as pollution treatment.
The rainwater may corrode the surface of metals, producing metal ion and further polluting surface runoff when the metals are exposed to rain. 2) The plastic fragments left after disassembly are inflammable materials with poor thermostability.
Raw material hazard index is used to describe the environmental hazard that may arise from the raw materials of imported metal and electrical appliance scraps, scrap wires, cables and motors, the assessment of which will be made mainly based on the rate of dangerous wastes contained in the raw materials and the proportion of unrecyclable wastes.
The environmental pollution caused by the enterprises processing and utilizing scrap metals mainly include the sewage coming from the water-separated copper wire crusher, the dust from loading and unloading as well as processing and utilizing of raw materials, waste gas from pyrogenic decomposition and gas cutting and the unrecyclable and dangerous wastes contained therein.
