Extraction, Hydro-Lipid Methylation and Esterification of Macroalgae Gracilaria caudata, Applying Heterogeneous Catalysis in Preparation of Biodiesel
Abstract
Biodiesel has the features and fits perfectly in environmental demands required to be a biofuel renewable, biodegradable and non-toxic presenting as a possible solution to alleviate the current problems caused by oil dependence by society, reducing some effects cause of global warming. This project reports the extraction of oils from macroalgae Gracilaria caudata and their use in the preparation of biodiesel, with the goal of extracting lipids from algae biofuel studied and prepared from the same. The methodology used to extract vegetable oils were hot extraction using hexane as the solvent and also the cold-extraction method using the solvent mixture chloroform/ methanol 2:1. The conversion method has been dihydro-esterification using sublimed iodine in the presence of alcohol, ethyl or methyl. This methodology and study can obtain interesting results for the application of biodiesel made from the raw material, even with low yield in the extraction of lipids believe a possible solution to this problem.
