Produção de γ-valerolactona a partir de furfural sobre zeólitas Hf/Al-beta – efeito da relação de sítios ácidos de Lewis e Brønsted
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, Câmpus São Carlos, 19/03/2020)Lignocellulosic biomass has been used as a sustainable alternative to organic derivatives of fossil origin for the production of intermediates and chemicals with higher added value. In this context, γ-valerolactone (GVL), ... -
Controle da relação de sítios ácidos de Lewis e Brønsted pela incorporação de Sn em zeólitas Y - efeito na seletividade a produtos durante a conversão one-pot de furfural
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, Câmpus São Carlos, 25/02/2021)In the last years, in the production of chemicals or intermediates, the use of bioderived feedstocks as alternative sources to those derived from fossil fuels, has progressively increased. In this context, the conversion ... -
