Purificação da glicerina bruta obtida da alcoólise de triglicerídeos
(Universidade Tecnológica Federal do ParanáPato Branco, 2011-12-02)
This project proposes a purification methodology for the gross glycerin obtained from the alcoholysis of triglycerides. The residual glycerin was characterized by purity and physico-chemical characteristics. The purification ...
An Automatic Biodiesel Decanting System for the Optimization of Glycerin Separation Time by Applying Electric Field and Temperature
(2021-01-01)
During biodiesel production, crude biodiesel and glycerin are separated in resting tanks due to gravity and differences in density, glycerin accumulates at the base of the contender; such operation is called decantation. ...

Purificação da glicerina obtida como coproduto na produção de biodiesel com óleo de soja refinado
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Química e Biologia, 2013-03-22)
This study aims to develop methologies for purifying glycerin coproduct generated in the production of biodiesel by transesterification of refined soybean oil. It was performed pre-purification of glycerine by acid hydrolysis ...
Water-free process for eco-friendly purification of biodiesel obtained using a heterogeneous Ca-based catalyst
(Elsevier Science, 2014-01)
The technologies conventionally used for biodiesel purification imply high consumptions of both energy and water. In the present work, biodiesel was produced by transesterification using a very active calcium glyceroxide ...
Biodiesel Purification Using Polymeric Nanofiltration Composite Membranes Highly Resistant to Harsh Conditions
(Wiley VCH Verlag, 2018-02)
Biodiesel as alternative for conventional diesel fuel is mainly produced by the catalytic reaction of triglycerides with an alcohol. In this work, the purification of biodiesel was carried out with two lab-made solvent-resistant ...

(Universidade Federal do ParáBrasilInstituto de TecnologiaUFPAPrograma de Pós-Graduação em Engenharia Química, 2022)
Reuse of Magnesol® for Purification of BiodieselA Purificação de Biodiesel com reaproveitamento de Magnesol®
(Universidade Federal de Santa Maria, 2022)
Aplicação da metodologia de superfície de resposta na otimização do processo de purificação da glicerina bruta residual da produção de biodiesel
(Universidade Tecnológica Federal do ParanáApucaranaBrasilLicenciatura em QuímicaUTFPR, 2017-06-23)
The growing national biodiesel production, through transesterification processes, generates an expressive amount of glycerol that can be used in several sectors of the national industry as long as it has a compatible purity ...
Biodiesel purification in one single stage using silica as adsorbent
(Elsevier, 2014-07)
In this paper a simple biodiesel purification method consisting of one single stage treatment with silica as adsorbent is described. The presented method seems a solution for biodiesel refining saving water, money and ...
