Aprovechamiento de las oleinas residuales procedentes del proceso de refinado de los aceites vegetales comestibles, para la fabricación de biodiesel
Se estudia un procedimiento para la obtención de Biodiesel a partir de las “Oleínas”. Biodiesel es un producto capaz de sustituir al combustible Diesel ordinario que se obtiene del petróleo y que consiste en una mezcla ...
Valorization of a high-acidity residual oil generated in the waste cooking oils recycling industries
(Consejo Superior de Investigaciones Científicas, CSIC: Instituto de la Grasa, 2019)
A sludge fraction is obtained from the industries which recycle cooking oil and this sludge con-tains a large amount of oil with an extremely high acidity (> 60%). In this work, we propose a scheme for methyl ester production ...
Esterification of Free Fatty Acids with Glycerol within the Biodiesel Production Framework
Companies in the field of the collection and treatment of waste cooking oils (WCO) for subsequent biodiesel production usually have to cope with high acidity oils, which cannot be directly transformed into fatty acid methyl ...
Production of Oxygenated Fuel Additives from Residual Glycerine Using Biocatalysts Obtained from Heavy-Metal-Contaminated Jatropha curcas L. Roots
This work aims to shed light on the use of two biochars, obtained from the pyrolysis at 550 C of heavy-metal-contaminated Jatropha curcas L. roots, as heterogeneous catalysts for glycerol esterification using residual ...
Biodiesel production from olive-pomace oil of steam-treated alperujo
Recently interest has been revived in the use of plant-derived waste oils as renewable replacements for fossil diesel fuel. Olive–pomace oil (OPO) extracted from alperujo (by-product of processed olives for olive oil ...
Production of Bio-Oils and Biochars from Olive Stones: Application of Biochars to the Esterification of Oleic Acid
Olive stones are a by-product of the olive oil industry. In this work, the valorisation of olive stones through pyrolysis was attempted. Before pyrolysis, half of the samples were impregnated with sulphuric acid. Pyrolysis ...
