Sustainable Biodiesel: Kinetic Study and Modeling of Catalytic Esterification of Used Vegetable Oils as The First Stage of the Production Process
(Asociación Química Argentina, 2017-04)
In an attempt to satisfy the needs for sustainable production of biofuel in industrial processes, thepresent work develops the esterification kinetics of used vegetable oils (UVOs) with ethanol,employing acidified sunflower ...
Investigation on the esterification of fatty acids catalyzed by the H3PW12O40 heteropolyacid
(Journal of the American Oil Chemists' Society, 2019)
Acid removal from crude oils by catalytic esterification naphthenic acid catalize by Mg/Al hydrotalcite
(Elsevier Science, 2019-10)
The presence of relatively high levels of naphthenic acids in crude oil may cause serious corrosion problem at temperature between 200 °C and 400 °C. One of the viable processes for decreasing acidity is the esterification ...
Production of biodiesel by esterification of palmitic acid over mesoporous aluminosilicate Al-MCM-41
(Elsevier B.V., 2009-03-01)
Biodiesel has been obtained by esterification of palmitic acid with methanol, ethanol and isopropanol in the presence of Al-MCM-41 mesoporous molecular sieves with Si/Al ratios of 8.16 and 32. The catalytic acids were ...
Cooperative effects of H+ and H- hydrido carbonyl ruthenium derivatives; role of homogeneous and heterogeneous protonic and lewis acids in catalytic hydrocarbonylation reactions
(Elsevier B.V., 1989-11-01)
The role played by H+ hydrido iodocarbonyl and H- hydrido carbonyl ruthenium catalysts in the different catalytic steps of hydroformylation and hydroesterification of olefins, and in the homologation of alcohols has been ...
