In Situ Transesterification of Microbial Biomass for Biolubricant Production Catalyzed by Heteropolyacid Supported on Niobium
(2022-02-01)
Lubricants are substances of the foremost importance in the modern world, as they are essential to the proper functioning of various mechanisms. Most lubricants, however, are still made from petroleum fractions. I light ...
The conversion of linoleic acid into hydroxytetrahydrofuran-structured bio-lubricant
(Academic Press Ltd - Elsevier Science Ltd, 2021-08-01)
In this work, a new structured linoleic-based hydroxytetrahydrofuran (HTHF) ester lubricant with excellent properties was developed. A synthesis route through regioselective enzymatic hydration was established, combining ...
Estudo tribológico de biolubrificantes com adição de nanopartículas de óxidos (zinco e cobre)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2013-08-02)
Currently, vegetable oils have been studied for bio-lubricants base that fits the new environmental standards. Since, in a world full of finite natural resources, mineral oils bring consequences to the environment due to ...
Natural and Modified Montmorillonite Clays as Catalysts for Synthesis of Biolubricants
(MDPI AG, 2018-09)
In this study, natural and modified clays were evaluated as catalysts in an esterification reaction to obtain bio-based lubricants. The biolubricants are environmentally preferred to petroleum-based lubricants because they ...
Enzymatic catalysis: An environmentally friendly method to enhance the transesterification of microalgal oil with fusel oil for production of fatty acid esters with potential application as biolubricants
(2020-08-01)
This work aimed at the enzymatic synthesis of fatty acid esters with potential application as biolubricants from microalgae oil and fusel oil using Burkholderia cepacia lipase immobilized on Nb2O5. The lipid-bearing ...
Study of oxide nanoparticles as additives for vegetable lubricants

Síntese e caracterização de biolubrificantes a partir do óleo de soja refinado
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Química e Biologia, 2011-11-30)
The rising prices of petroleum products, dependence on an non-renewable rawmaterials and the various environmental impacts caused by industry have motivated researchers to look for alternative energy and production of goods ...
Caracterização do óleo de carnaúba para uso como biolubrificante
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2014-02-03)
Lubricant is responsible for reducing the wear on the friction protect the metal
against oxidation, corrosion and dissipates excess heat, making it essential for the
balance of a mechanical system, consequently prolonging ...
