Conversion of glycerol to lactic acid catalyzed by platinum supported on activa...
Arcanjo, Maria Rosiene Antunes; Barros, Fernando José Soares; Silva Júnior, Ivanildo José da; Rodríguez-Castellón, Enrique; Infantes-Molina, AntoniaProduction of lactic acid by conversion of glycerol by heterogenous catalyst is an option to process the large amounts of glycerol. The platinum supported activated carbon catalyst were characterized by XRD, SEM, EDX, TEM and N2 physical adsorption. This catalyst was evaluated for the conversion of glycerol into lactic acid, analyzing the reaction following factors: catalyst loading, catalyst weight, molar rati...
Estudo do processo de purificação do xilitol obtido por rota fermentativa utili...
Albuquerque, Tiago Lima de; Serafim, Leonardo Farias; Arcanjo, Maria Rosiene Antunes; Marques Junior, José Edvan; Silva Júnior, Ivanildo José daA via biotecnológica é uma alternativa para a produção de xilitol, poliol com utilização na indústria alimentícia e farmacêutica.Contudo, são escassos os estudos que visem à recuperação dessa substância a partir dos meios de cultivo microbiano. Assim, objetivou-se avaliar o processo de purificação do xilitol obtido por processo biotecnológico utilizandoa leveduraKluyveromyces marxianusCCA510e meio semissintétic...
Conversão de glicerol em ácido lático utilizando catalisadores heterogêneos de ...
Arcanjo, Maria Rosiene AntunesFor every 9 tons of biodiesel produced, about 1 ton of crude glycerol is formed. By 2020 it is estimated that world production of glycerol will reach 3 million tons, while its demand will not exceed 500 thousand tons, so alternatives are needed for the use of residual glycerol in order to ensure both economic viability of the biodiesel production and the impact generated in the environment with this surplus vol...
Estudo da adsorção de Ácido Lático por cromatografia de troca iônica
Arcanjo, Maria Rosiene AntunesCurrently the demand for renewable fuels has increased a lot. Thus, biodiesel is an alternative to oil and its derivatives, since its production is cheaper, there is a reduction in emissions, and is considered a renewable energy. Due to government incentives that drive the production of biodiesel, such fuel has been produced on a large scale. Of all the raw material used for producing biodiesel via transesterif...
