Journal ArticleDOI
Rice husk ash as an adsorbent for purifying biodiesel from waste frying oil
Márcia Cardoso Manique,Candice Schmitt Faccini,Bruna Onorevoli,Edilson Valmir Benvenutti,Elina Bastos Caramão +4 more
TL;DR: In this article, the authors used rice husk ash (RHA) for the purification of biodiesel from waste frying oil (WFO) using RHA at concentrations of 1, 2, 3, 4, and 5% and compared it with two other different purification methods, the traditional acid solution (1% aqueous H3PO4) and with the commercial adsorbent Magnesol® 1% (w/w).
Journal ArticleDOI
A one-dimensional and comprehensive two-dimensional gas chromatography study of the oil and the bio-oil of the residual cakes from the seeds of Crambe abyssinica
Bruna Onorevoli,Maria Elisabete Machado,Cláudio Dariva,Elton Franceschi,Laiza Canielas Krause,Rosângela Assis Jacques,Elina Bastos Caramão +6 more
TL;DR: In this paper, the evaluation of Crambe abyssinica as a source of bio-energy and biomass was performed by using GC/qMS and GC/TOFMS, and many oxygenated compounds were found in both (VO and BO).
Journal ArticleDOI
Characterization of feedstock and biochar from energetic tobacco seed waste pyrolysis and potential application of biochar as an adsorbent
Bruna Onorevoli,Gabriela Pereira da Silva Maciel,Maria Elisabete Machado,Valeriano Antonio Corbelini,Elina Bastos Caramão,Elina Bastos Caramão,Rosângela Assis Jacques +6 more
TL;DR: In this article, a material with great adsorption potential was obtained from the residual cake from the extraction of energetic tobacco seeds, which was characterized and subjected to pyrolysis in nitrogen flow, resulting in bio-oil and biochar.
Journal ArticleDOI
Production of activated biochar from coconut fiber for the removal of organic compounds from phenolic
Mozart Daltro Bispo,Jaderson K. Schneider,Diego da Silva Oliveira,Debora Tomasini,Gabriela Pereira da Silva Maciel,Tiago Schena,Bruna Onorevoli,Thiago Rodrigues Bjerk,Rosângela Assis Jacques,Laiza Canielas Krause,Elina Bastos Caramão +10 more
TL;DR: In this paper, the activation of the biochar produced in the pyrolysis of agroindustrial residue (fiber) of the green coconut was studied, being done with sodium carbonate (Na2CO3) at high temperature.
Journal ArticleDOI
Production of rice husk bio-oil and comprehensive characterization (qualitative and quantitative) by HPLC/PDA and GC × GC/qMS
Eliane Lazzari,Allan dos S. Polidoro,Bruna Onorevoli,Tiago Schena,Aline Nunes Silva,Enelise Scapin,Rosangela Assis Jacques,Elina Bastos Caramão +7 more
TL;DR: In this article, the authors used response surface methodology (RSM) to determine the optimal pyrolysis conditions for the rice husk (RH) dry bio-oil production using central composite design (CCD).
