Biodiesel production from coconut oil
Biodiesel production processes using coconut oil containing a relatively high content of free fatty acids (4.5% w/v and higher) have been characterized using alkali, acid and enzymatic- based catalysts. The use of ethanol (molar ratio of 3:1 of ethanol:triglycerides) instead of methanol was …

Optimising microalgal lipid productivity for biodiesel production
… deprivation that optimise lipid productivity for biodiesel production. This was carried out by I) developing the tools necessary to measure lipid productivity accurately, II) identifying and quantifying the key characteristics of promising microalgal strains, initially through a literature survey …

Enhancing biodiesel production from soybean oil using ultrasonics
<p>Biodiesel, or fatty acid alkyl ester, is a non-toxic, biodegradable and renewable source of energy. It is mostly produced from vegetable oils. Other sources include animal fat, oils obtained from algae, fungi, bacteria, etc. Esterification of oil with alcohol in the presence of moderate …

Mechanistic Modeling of Biodiesel Production via Heterogeneous Catalysis
Biodiesel has emerged as a promising renewable and clean energy alternative to petrodiesel. While biodiesel has traditionally been prepared through homogeneous basic catalysis, heterogeneous acid catalysis has been investigated recently due to its ability to convert cheaper but high free fatty acid …

BIODIESEL PRODUCTION THROUGH MICROWAVE ASSISTED TRANSESTERIFICATION OF MICROBIAL CELLS
… studied to grow on several substrates including biodiesel production byproduct crude glycerol and sweet sorghum juice. After cultivation, yeast cells were heated under microwave radiation to extract lipid and produce biodiesel through in-situ transesterification. Firstly, the yeast growth with …

Characterization of Fresh Water Microalgae from East Tennessee for Biodiesel Production
… harmful byproducts in the environment. Biodiesel emits less gaseous pollutants than diesel. There are various sources for biodiesel but they are unable to meet the existing demands for fuel. Microalgae are a promising source for biodiesel because of its relatively faster growth rate, …

Sulfate and Hydroxide Supported on Zirconium Oxide Catalysts for Biodiesel Production
Biodiesel is currently produced by homogeneous catalysis. More recently however, heterogeneous catalysis is being considered as a cheaper alternative to the homogeneous process. In this research project, heterogeneous catalysts of zirconium oxide were produced by impregnation. Zirconium oxide …

Microalgal Biodiesel Production through a Novel Attached Culture System and Conversion Parameters
Due to a number of factors, the biodiesel industry in the United States is surging in growth. Traditionally, oil seed crops such as soybean are used as the feedstock to create biodiesel. However, the crop production can no longer safely keep up with the demand for the growing biodiesel industry. …

Multistage methanolysis of crude palm oil for biodiesel production in a pilot plant
… The ultimately proposed kinetic models of the biodiesel production from crude palm oil and methanol under the presence of a base catalyst follow the second order differential equations without a shunt reaction. The emphasis of this re�search work is on the study of the methanolysis of the crude …

Growth of Chlorella vulgaris and Chlamydomonas reinhardtii for biodiesel production and carbon dioxide capture
The growth of two strains of green microalgae, Chlorella vulgaris (UTEX 2714) and Chlamydomonas reinhardtii (UTEX 90) was tested in three types of media; Tris Acetate Phosphate (TAP), Bushnell Haas Broth (BHB), and Wright's Cryptophytes (WC buffered with either glycylglycine or Tris-base). Also, …
