There are some challenges about NOX emissions exhausted from diesel engines fueled with biodiesel. Due to increasingly stringent emission regulations, the different methods such as varying the engine operating parameters, treatment with antioxidant...

In situ transesterification was applied for biodiesel production from dry Chlorella sp. biomass. Aim of this study was to achive the optimum reaction time for direct transesterification. In order to investigate the effect of reaction time...

Microalgae have been receiving considerable interest among various sources for biodiesel production. Due to microalgae’s small cell size and low density, there are technical challenges in their harvesting process. As an economical viable method...

Lipid extraction is the bottleneck step for algaebased biodiesel production. Herein, 12 solvent mixture

systems (mixtures of three non-polar and two polar organic

solvents) were examined to evaluate their effects on the...

Preparation of suitable catalysts has been concerned in production of biodiesel from oil with high FFA as west cooking oil. In this study, the catalytic activity of prepared Al-promoted and pure sulfated zirconia by solvent-free method...

Microalgae, the world’s largest group of photosynthetic organisms, convert atmospheric CO2 to polar and neutral lipids using sunlight, which after esterification can be utilized for biodiesel production. This article represents possible production...

]. The renewable biofuels can decrease the release of harmful chemical substances for the environment in comparison with common diesel fuels. Among different types of biofuels, production of biodiesel has received much attention during recent years [2]. In order...

In the past few years, due to environmental problems and the depletion of fossil fuels, concern has been raised for a need in the development of renewable fuel such as biodiesel fuel. The most common ways of producing biodiesel is by esterification...
