At the moment different ferrous, non-ferrous materials and industrial blue wax have been used for prototype models. However such materials is very expensive. Hence an attempt is made to substitute these materials by the palm oil based bio-wax produced in Malaysia. In this research, the authors will analyze and investigate whether there is a possibility to use the palm oil based bio-wax material to substitute with the petroleum based industrial-wax. Experimental analyses are carried out to investigate the capability and the strength of the palm oil based bio-wax material. The matrix blends were prepared of fatty acids from oleo-chemicals, palm oil wax, natural ash fibre and low linear density polyethylene （LLDPE） by stirring and melt-mixing. Sample b!ends are machined with lathe machining process. The sample blends showed there was no built edge formation and good smooth surface production.展开更多

Currently, the Algerian refining industry has to be adapted to meet demand progress both in terms of volume and also in terms of specifications, in a general context marked by a strong volatility of the oil markets. Commonly, refining operations planning models are based on a deterministic linear programming. However, because of the demand fluctuation, and other conditions for the market, many parameters should be considered as uncertain such as the demand and the exportation. The impact of such uncertainties on the development＇s pattern of refining capacities is analyzed with a stochastic model. Finally, the results of both deterministic and stochastic models are compared.展开更多
