Exploring and improvement of biodiesel production from non-edible vegetable oil is one of the effective ways to solve limited amount of traditional raw materials and their high prices. The main objective of this study is to optimize the biodiesel production process parameters (methanol-to-oil ratio, agitation speed and concentration of the potassium hydroxide catalyst) of a biodiesel derived from...
The non-edible oil from Schleichera oleosa possesses the potential as a feedstock for biodiesel production. In this study, the biodiesel production was performed using two-step transesterification process on a laboratory scale. The parameters studied were reaction temperature, molar ratio of methanol to oil, catalyst concentration, reaction time and catalysts type. An analysis of variance (ANOVA)...
Hybrid system based on photovoltaic is considered an effective option to electrify remote and isolated areas far from grid. This is true for areas that receive high averages of solar radiation annually. Using microturbine as a standby source will make utilization of hybrid systems more attractive. A sizing optimization of the hybrid system components, an economic feasibility study and a complete design...
To reduce energy consumption in the buildings and minimize negative environmental impacts, it is necessary to determine the operating condition that provides optimum system performance. Entropy or exergy analysis can be used as a reliable tool for analyzing energy consumption and environmental impact. This paper describes the modelling and optimization analysis for cooling system in the building....
