Shenbaga Devi, A., P. Santhanam, V. Rekha, S. Ananth, B. Balaji Prasath, R. Nandakumar, S. Jeyanthi and S. Dinesh Kumar Culture and biofuel producing efficacy of marine microalgae Dunaliella salina and Nannochloropsis sp. J. Algal Biomass Utln. 2012, 3 (4): 38–4 Abstract Biodiesel from oil crops, waste cooking oil and animal fat cannot realistically satisfy even a small fraction of the existing...

This study reports the conversion of Jatropha curcas oil to biodiesel catalyzed by sulphated zirconia loaded on an alumina catalyst using response surface methodology (RSM). Specifically, it studies the effect of interaction between process variables on the yield of biodiesel. Jatropha is found to be survived in different locations in South-East Asia. Jatropha oil is favoured to palm oil for it...

The rapid increase in production of ethanol from corn and other grains and biodiesel from various fats and oils has resulted in growing quantities of byproducts from these industries, primarily distillers dried grains with solubles (DDGS) from the ethanol industry and glycerol from biodiesel production. The use of DDGS in poultry and swine diets is not new, but the supply of product encourages ...

This paper discusses the feasibility of the use of ionic liquids as catalysts in the biodiesel production field, describing some studies already published in the literature on this theme. Ionic liquids are regarded as a new generation of catalysts in the chemical industry, with several uses in different commercial segments. However only a few publications involving this topic can be found in th...

Microalgae represent a sustainable energy source because of their high biomass productivity and ability to remove air and water born pollutants. This paper reviews the current status of production and conversion of microalgae, including the advantages of microalgae biodiesel, high density cultivation of microalgae, high-lipid content microalgae selection and metabolic control, and innovative ha...

The utilization of bioethanol as the alcohol source for biodiesel production is more environmentally advantageous over methanol owing to its lower toxicity, lower flammability and its sustainable supply from renewable agricultural resources. However, as the presence of water in crude bioethanol is the critical factor limiting the biodiesel production process, the energy-intensive and costly pur...

This experiment is an investigation of used cooking oil as a sustainable and renewable resource for methyl ester production. with more than 95.5% production yield, thermally activated hydrated cement has been carefully discussed as a catalyst in the transesterification of used cooking oil into methyl ester to use waste cement as a heterogeneous catalyst for methyl ester production through elect...

Background Biodiesel has emerged as a energy, environmental and social solution proposal. However, there are some technical challenges that need to be solved, for example, use of the by-product of biodiesel production, crude glycerol (CG). To avoid future problems caused by the accumulation of CG and simultaneously make biodiesel production more competitive, the search for the most viable alter...

In this study, we propose a mixed integer nonlinear programming (MINLP) model for superstructure based optimization of biodiesel production from microalgal biomass. The proposed superstructure includes a number of major processing steps for the production of biodiesel from microalgal biomass, such as harvesting of microalgal biomass, pretreatments including drying and cell disruption of harvest...
